Αυτή η εργασία περιγράφει το όραμα των προσωποκεντρικών επικοινωνιών (I centric communications). Ο κύριος στόχος της εργασίας είναι η εστίαση στις διάφορες πτυχές των προσωποκεντρικών επικοινωνιών. Η επικοινωνιακή συμπεριφορά των ανθρώπων χαρακτηρίζεται από συχνές αλληλεπιδράσεις με ένα σύνολο από αντικείμενα στο περιβάλλον τους, τα οποία αποτελούν τον προσωπικό επικοινωνιακό τους χώρο. Η προσέγγιση των προσωποκεντρικών επικοινωνιών είναι η δημιουργία επικοινωνιακών συστημάτων τα οποία δεν βασίζονται σε συγκεκριμένες τεχνολογίες αλλά στην ανάλυση του προσωπικού επικοινωνιακού χώρου. Το αποτέλεσμα είναι ένα σύστημα επικοινωνίας το οποίο προσαρμόζεται σε συγκεκριμένες ανάγκες του κάθε ατόμου. Ένα τέτοιο σύστημα μπορεί να ενεργεί σύμφωνα με τις απαιτήσεις του ανθρώπου, αντανακλώντας πρόσφατες ενέργειες ώστε να επιτρέπει την δημιουργία προφίλ και την προσαρμογή του σε αυτές. Μία τεχνολογία κατάλληλη για τέτοιου είδους συστήματα είναι η τεχνολογία UPnP η οποία ορίζει μία αρχιτεκτονική δικτύου για διάχυτη ομότιμη συνδεσιμότητα για ευφυείς συσκευές, ασύρματες συσκευές και υπολογιστές. Η UPnP τεχνολογία παρέχει μία κατανεμημένη αρχιτεκτονική ανοιχτής δικτύωσης που επιτρέπει σε TCP/IP και Web τεχνολογίες εκτός του ελέγχου και της μεταφοράς δεδομένων μεταξύ δικτυωμένων συσκευών, την αρραγή δικτύωση γειτνίασης. Εν συνεχεία, περιγράφεται η διαδικασία απόκτησης μίας διεύθυνσης δικτύου κατά την εισαγωγή μίας συσκευής σε ένα δίκτυο. Μετά την απόκτηση της ΙΡ διεύθυνσης για να μπορεί ο δυναμικός ξενιστής να στείλει ΙΡ πακέτα στο συνδεδεμένο σε αυτό δίκτυο, πρέπει να προσδιορίσει την διεύθυνση ενός τουλάχιστον λειτουργικού δρομολογητή. Τέλος, περιγράφεται η διαδικασία με την οποία κόμβοι του δικτύου, όπως οι δρομολογητές και οι ξενιστές ανακοινώνουν την εγγραφή τους σε μία ομάδα πολυεκπομπής. / This thesis describes the vision of I centric communications. The main objective of this thesis is to focus on the various aspects of I centric communications. The communication behaviour of human beings is characterized by frequent interactions with a set of objects in their environement. The set of objects, controlled by each individual, define its individual communication space. The approach of I centric communications is to build communication systems not based on specific technologies, but on the analysis of the individual communication space. The result is a communication system that adapts to the specific demands of each individual. Such a system will act on behalf of human’s demands, reflecting recent actions to enable profiling and self adaptation. I centric Services adapt to individual communication spaces and situations. A suitable technology for such communication systems is UPnP technology, which is a new architecture for pervasive peer-to-peer connectivity of intelligent appliances, wireless devices and PCs. UPnP technology provides a distributed, open networking architecture that enables TCP/IP and Web technologies to provide seamless proximity networking in addition to control and data transfer among networked devices. Furthermore, a procedure of allocating network addresses is described during the entry of a device in the network. After acquiring an IP address, the dynamic host has to discover the address of at least one operational router on its directly attached subnet so that they are capable of sending IP datagrams in that subnet. In conclusion, the way by which network nodes, such as hosts and routers, report their IP multicast group memberships to any neighboring multicast routers, is described.

The thesis purpose was to develop a framework for coordination of devices over mobile environment. The framework is specially designed for mobile devices due to constraints in mobiles of less memory and resources, enables zero configuration for communication. The purpose of study was to investigate existing tools and technologies for mobile communication. For this purpose UPnP (Universal Plug and Play) architecture is investigated over Prism-MW (Programming in the small and many - middleware) for android platform. We have developed the control point devices communicate with server devices. And also we have developed demonstrator application to show how devices will work.

Home routers are common in every household that has some kind of Internet connectivity. These embedded devices are running services such as web, file and DHCP server. Even though they have the same security issues as regular computers, they do no run protection software such as anti-virus and they are not updated. Moreover, the importance of these devices is misjudged; all network traffic is passing through them and they control the DNS of the network while, in most cases, they are on-line around the clock. When more and more non-Internet features are implemented into home routers, such as Voice over IP and network storage, their role becomes more special and many security concerns are raising. In this thesis, we investigate the issues resulting from this special role; the importance for these devices to be secure, the attacking vector and how the devices can be compromised to be part of a large home router botnet. We conclude by proposing ways to make the current implementation more secure, suggesting ways to protect routers from botnets without user interaction, that is from the ISP, while respecting the privacy of the end user and we identify what future work needs to be done. / Router är vanliga i hem som har någon slags Internet anslutning. De här inbyggda enheter kör tjänster som t.ex. web, file och DHCP basenheter. Fastän de har samma säkerhetsfrågor som vanliga datorer, så kan de inte använda säkerhets mjukvara som t.ex anti-virus och de är inte uppdaterade. Dessutom har betydelsen av de här apparaterna blivit felbedömmat; hela nätverket passerar genom dem och de kontrolerar nätverkets DNS medan, i de flesta fall, de är on-line dygnet runt. Men, när mer och mer icke-Internet lockvaror fars in i routern, som t.ex Voice över IP och nätverkslagring, blir deras roll viktigare och oron för säkerheten växer. I den här avhandlingen utforskars problemen och frågorna som efterföljer deras speciella roll, hur viktigt det är att de här apparaterna är skyddade, (the attacking vector) och hur de här apparaterna kan bli jämkningad för att bli en del av ett stort router botnet. Vi avsluter med att lägga fram sätt att göra det nuvarande verktyget mer skyddat, föreslå sätt att skydda routern från botnet utan användarinteraktion, som kommer från ISP, medan man respekterar det andra användarens privtaliv och markera vad som behövs ändras i framtiden.

We describe CoSMo, a Cognitively Inspired Service and Model Architecture for situational awareness and monitoring of vehicular traffic in urban transportation systems using a network of wireless sensors. The system architecture combines (i) a cognitively inspired internal representation for analyzing and answering queries concerning the observed system and (ii) a service oriented architecture that facilitates interaction among individual modules, of the internal representation, the observed system and the user. The cognitively inspired model architecture allows one to effectively respond to deductive as well as inductive queries by combining simulation based dynamic models with traditional relational databases. On the other hand the service oriented design of interaction allows one to build flexible, extensible and scalable systems that can be deployed in practical settings. To illustrate our concepts and the novel features of our architecture, we have recently completed a prototype implementation of CoSMo. The prototype illustrates advantages of our approach over other traditional approaches for designing scalable software for situational awareness in large complex systems. The basic architecture and its prototype implementation are generic and can be applied for monitoring other complex systems. CoSMo's architecture has a number of features that distinguish cognitive systems. This includes: dynamic internal models of the observed system, inductive and deductive learning and reasoning, perception, memory and adaptation. This thesis describes the service oriented model and the associated prototype implementation. Two important contributions of this thesis include the following: The Generic Service Architecture - CoSMo's service architecture is generic and can be applied to many other application domains without much change in underlying infrastructure. Integration of emerging web technologies - Use of Web Services, UPnP, UDDI and many other emerging technologies have taken CoSMo beyond a prototype implementation and towards a real production system. / Master of Science

Approved for public release, distribution is unlimited / As more and more devices with a variety of capabilities are Internet-capable, device independence becomes a big issue when we would like the information that we request to be correctly displayed. This thesis introduces and compares how existing standards create a profile that describes the device capabilities to achieve the goal of device independence. After acknowledging the importance of device independence, this paper utilizes the idea to introduce a Device-Aware Network (DAN). DAN provides the infrastructure support for device-content compatibility matching for data transmission. We identify the major components of the DAN architecture and issues associated with providing this new network service. A Device-Aware Network will improve the network's efficiency by preventing unusable data from consuming host and network resources. The device profile is the key issue to achieve this goal. / Captain, Taiwan Army

<p>Media extenders or digital media receivers are network devices that are used to retrieve digital media files (such as music, pictures, or video) from a media server and play or show them on a TV or home theater system. A technology that is often associated with these devices is the Universal Plug and Play (UPnP) technology. This technology enables network devices to be used without requiring the user to do network configuration on it. This thesis demonstrates how a device that is normally used for receiving digital television broadcasts can be enhanced to support media extender functionality. The thesis describes the design and implementation of the technologies that are needed to accomplish this functionality. The main topics are centered around on how UPnP awareness and media rendering (decoding) are incorporated into the device.</p>

Recent developments in embedded systems give robots access to the Internet and make them more flexible and capable of performing more complex applications. However, these robots are still limited in terms of size, CPU power, storage resources and memory. Consequently, these robots have only been manufactured for certain specific applications and cannot be re-used for other applications. This presents us with a challenge to design a software framework - Robot Colony. The Robot Colony enables robots to be suitable for a wide range of applications, not originally received from manufacturers, to achieve greater functionality, flexibility and utility. This research outlines the architecture and functionality of the Robot Colony to support the collaboration between devices in the P2P community and also analyse the JXTA platform, which was the framework originally proposed. Lastly we present a customized P2P architecture that specifically addresses the interaction betweensoftware components across the network. We further discuss the following technologies applied in theframework: * XML-based Directory Service Provider * HTTP-based publish/describe control commands * Remote Process Invoke To fully complete the project, a thorough evaluation of the framework based on either the JXTAplatform or the customized P2P channel has been conducted. This evaluation provides basic statistics data for the proposed framework design and implementation. Further more, we have presented a realtime Demo at the Smart Device lab of the Queensland University of Technology.

This thesis covers design and implementation of a media system solution for home networks with personal computers and a set-top box. In a home there are effectively two independent media systems with the same purpose: the personal computer and the digital set-top box, with the purpose of delivering digital media in form of audio and video to the consumer. The goal of the thesis work was to implement a solution that bridges the gap between the two systems, so that the user, from the set-top box, can play back media that is actually stored on one or several personal computers. Our solution is based on UPnP technology, which is used for service discovery and control. The choice of UPnP is motivated by an evaluation of discovery protocols, which concludes that UPnP is the most suitable technology in this particular system. Also, an evaluation of suitable transport protocols was done. Here,HTTP was used. For the personal computer, a media server and a graphical user interface for configuring the media server were created. For the set-top box, a media client, and a graphical user interface for browsing the content of the media server, were created. In conclusion, the creation of the prototype was successful and the set-top box was able to playback media that had been shared by the PC on the network.
