Balancing of Network Energy using Observer ApproachPatharlapati, Sai Ram Charan 02 December 2016 (has links) (PDF)
Efficient energy use is primarily for any sensor networks to function for a longer time period. There have been many efficient schemes with various progress levels proposed by many researchers. Yet, there still more improvements are needed. This thesis is an attempt to make wireless sensor networks with further efficient on energy usage in the network with respect to rate of delivery of the messages.
In sensor network architecture radio, sensing and actuators have influence over the power consumption in the entire network. While listening as well as transmitting, energy is consumed by the radio. However, if by reducing listening times or by reducing the number of messages transmitting would reduce the energy consumption. But, in real time scenario with critical information sensing network leads to information loss. To overcome this an adaptive routing technique should be considered. So, that it focuses on saving energy in a much more sophisticated way without reducing the performance of the sensing network transmitting and receiving functionalities.
This thesis tackles on parts of the energy efficiency problem in a wireless sensor network and improving delivery rate of messages. To achieve this a routing technique is proposed. In this method, switching between two routing paths are considered and the switching decision taken by the server based on messages delivered comparative previous time intervals. The goal is to get maximum network life time without degrading the number of messages at the server. In this work some conventional routing methods are considered for implementing an approach. This approach is by implementing a shortest path, Gradient based energy routing algorithm and an observer component to control switching between paths. Further, controlled switching done by observer compared to normal initial switch rule. Evaluations are done in a simulation environment and results show improvement in network lifetime in a much more balanced way.

Dynamic Routing and Load Balancing Techniques for Integrated Access and Backhaul Network / Dynamisk Dirigering och Lastbalansering Tekniker för Integrerad Åtkomst och Backhaul NätverkLiang, Yung-Chin January 2020 (has links)
Mobile networks have rapidly evolved over decades, and have arrived at the fifth generation (5G) system in recent years. From 2019, companies started to bring 5G networks into business, providing higher data rates, lower latency, and larger network capacity to the world. One of the main advancements in 5G network systems is the use of millimetre waves for wireless transmission. This not only grants higher throughput with wide bandwidth but also introduces new challenges to the radio access networks in 5G systems. To tackle the challenges, a new type of network, which is called the Integrated Access and Backhaul (IAB) network, has been proposed as a deployment solution for 5G cellular networks. In this work, we investigate the routing mechanism of an IAB network and propose a novel load balancing algorithm that can be applied to the IAB network for improvement in throughput as well as load distribution. We extend the work from previous studies on IAB networks and evaluate the performance of the proposed algorithm in comparison to previous work. Through radio network simulations, we find that the shortest path routing outperforms a greedy algorithm in terms of path selection in the network and that the proposed algorithm achieves load balancing among the network, combined with an improvement in the user throughput. Finally, we conclude our work and suggest directions for future work in the study of IAB networks. / Mobilnäten har utvecklats snabbt de senaste decennierna och är nu framme vid femte generationens system (5G). Under 2019 började telekomföretag lansera 5G-nätverk, med högre datahastigheter, lägre fördröjningar och högre nätverkskapacitet. Ett av de största framstegen inom 5G-nätverkssystem är användningen av millimetervågor för trådlös överföring. Detta ger högre datahastigheter och större bandbredd, men leder också till nya utmaningar för radioaccessnätverket. För att hantera några av dessa har en ny typ av nätverk, kallat Integrated Access and Backhaul (IAB) föreslagits. I det här arbetet undersöker vi routingmekanismer för ett IAB-nätverk och föreslår en ny lastbalanseringsalgoritm som kan användas för att förbättra såväl genomströmning som lastfördelning. Arbetet är en utvidgning av tidigare studier av IAB-nätverk och jämför prestanda för den nya algoritmen med tidigare förslag. Genom simuleringar har vi funnit att shortest path routing överträffar en ”greedy” algoritm när det gäller vägval i nätverket och att den föreslagna algoritmen uppnår såväl lastbalansering som förbättrad genomströmning. Avslutningsvis ges förlag till fortsatt arbete inom studiet av IAB-nätverk.
