With the increasing popularity of Internet of Things (IoT), network connected devices and sensors, to easier collect data is security an aspect that must not be forgotten. When sensitive data, such as personal or private data, is sent over the network without protection can it easier be obtained by anyone who want to get their hands on it. This risk increases with the value of the data sent and an increase in security should therefore follow this value. Based on this is it therefore important to look at the security aspects of a sensor network to find ways to easy integrate security such as authentication. This to make sure that the only devices and users accessing or sending data on the network is authorized and not malicious devices. This thesis focuses on the authentication and identification of the devices joining the network to make sure that only trusted devices would be able to join. The protocol in focus is ZigBee but the proposed solution can be integrated with any protocol and utilizes a Key Distribution Center (KDC) together with an authentication method based on the Challenge Handshake Authentication Protocol (CHAP) to authenticate new devices before they are allowed into the network. This solution is secure and relatively simple which makes it easy to integrate with any sensor network. / Med en ökad popularitet av att koppla upp sensorer och apparater mot ett nät- verk för att enklare kunna samla in data är säkerhet en aspekt som inte får glömmas bort. När känslig data, så som personlig eller privat data, skickas över nätverket oskyddat kan någon som vill komma åt datan lättare få tag på den. Denna risk ökar med värdet av datan som skickas och en ökningen av säkerhet bör darav följa ökning av värdet på datan. Utav denna anledning är det viktigt att se över säkerheten i sensornätverk och finna lösningar som lätt kan integreras med ett sensornätverk. Detta för att säkerhetsställa att endast de snesornoder som har auktoritet kan gå med i, samt skicka data på nätverket och därmed undvika oönskad åtkomst. Denna avhandling fukuserar på autentisering och identifiering av de noder som ska anslutas till nätverket för att säkerhetsställa att endast pålitliga och auktoriserade noder blir insläppta. Det protokoll som är i fokus i denna avhandling är ZigBee men den föreslagna lösningen kan även integreras med andra protokoll. Den föreslagna lösning- en använder sig även av ett Key Distribution Center (KDC) samt en autentiseringsmetod som baseras på Challenge Handshake Authentication Protocol (CHAP) för att authentisera nya noder innan de blir insläppta i nätverket. Denna lösning är säker och relativt enkel vilket gör det enkelt att integrera med all typer av sensornätverk.

At present, enterprises adopt global production and marketing strategy to reinforce their competitive advantages. In addition, they tend to search suitable places for establishing global logistic distribution centers. An international harbor with good geography, cost advantage, and complete facilities, will be attractive for those enterprises to set global logistic distribution centers. The Kaohsiung Harbor is the third largest container transport in the world. However, the global logistics is operated at the beginning stage. To match the developing plans of the government's global logistics, this exploratory study is designed to develop a strategy for the global logistic distribution center in Kaohsiung Harbor with Delphi Method and Analytic Hierarchy Process. Through literature review and two rounds Delphi Questionnaire, we find five evaluating criteria (operating efficiency, administrative efficiency, tax incentive, infrastructure and logistic professions) for positioning the Kaohsiung Harbor in global logistics. Five major functions including transit shipment, container consolidation, distribution, simple processing and warehousing are inducted. Three alternatives for global logistic distribution center are centralized, decentralized, or mixed type. Major findings of this study are as follows: 1.Centralized global logistic distribution center is the best type for Kaohsiung Harbor. 2.The priority of the major functions for a centralized global logistic distribution center in orders is simple processing, distribution, warehousing, container consolidation, and transit shipment. 3.The criteria for evaluating centralized global logistic distribution center in orders are administrative efficiency, operating efficiency, tax incentive, logistic professions and infrastructure. According to the results, researcher offers a strategy for developing global logistic distribution center in Kaohsiung Harbor.

In order to serve its customers more efficiently, most corporations have opted to centralize inventories in the form of distribution centers (DCs). However, this type of operation, which is often composed of a large number of vehicles that travel long distances, contribute to the increase in emissions and deposition levels of various atmospheric pollutants. The objective of this research was to make a case study of a distribution center of a supermarket chain, evaluating atmospheric emissions and total depositions in the region's water bodies, for some of the most common pollutants released in the incomplete combustion that occurs in the engines like Carbon Dioxide (CO2), Hydrocarbons (HC), Nitrogen Oxides (NOx) and Particulate Matter (PM). A routing was also proposed, using the algorithm of the nearest neighbor, aiming at reducing the kilometers traveled by the fleet, in order to reduce the impacts generated. The calculations of the emissions for the current operation of the DC, as for the new proposed route were made using the Top-Down and Bottom-Up methods, and the calculations of the total depositions made as proposed in the literature. The annual emissions currently found were approximately 4.700 tons, 193 kg, 10.615 kg and 103 kg for CO2, HC, NOx and PM, respectively. The total d...

Os cálculos das emissões para o funcionamento atual do CD, como para a nova rota proposta foram feitas utilizando-se os métodos Top-Down e Bottom-Up, e os cálculos das deposições totais feitas conforme o proposto na literatura. As emissões anuais encontradas atualmente foram de aproximadamente 4.700 toneladas, 193 kg, 10.615 kg e 103 kg para o CO2, HC, NOx e MP, respectivamente.

As emissões anuais encontradas após a roteirização foram de aproximadamente 1.310 toneladas, 53 kg, 2.957 kg e 29 kg para o CO2, HC, NOx e MP, respectivamente, e as deposições totais nos corpos d’água de 1,32 kg de HC, 328 kg de NOx, 2,50 kg de MP10 e 1,10 kg de MP2.5. Portanto, com a roteirização simulada foi possível uma redução nas emissões e nas deposições por volta de 72%, podendo-se concluir que maiores devem ser as atenções dadas a esse tipo de operação para minimizar os impactos negativos tanto à saúde da população quanto ao meio ambiente. / The changes in market dynamics due to technological advances, globalization and a significant increase in the range of products offered, have caused companies to review their logistics systems.

The total deposition in the bodies of water of 4,74 kg of HC, 1.777 kg of NOx, 9,0 kg of PM10 and 4,0 kg of PM2.5. The annual emissions found after routing were approximately 1.310 tons, 53 kg, 2.957 kg and 29 kg for CO2, HC, NOx and PM, respectively, and the total depositions in water bodies of 1,32 kg of HC, 328 kg of NOx, 2,50 kg of PM10 and 1,10 kg of PM2.5. Therefore, with simulated routing, it was possible to reduce emissions and depositions by 72%, and it can be concluded that greater attention should be given to this type of operation to minimize negative impacts on both the population's health and the environment.
