ROUTE QUALITY EVOLUTION WITH MOBILE SINK IN WIRELESS SENSOR NETWORKS USING QOS PARAMETERS

摘要

An energy-effective routing is a fundamental task in a Wireless Sensor Network (WSN) topology. It supplies a better cost metric covering wireless route quality. Quality of Service(QoS) is behold critical design disquiet in routing protocols for WSN. Both energy and QoS parameters are used to assess network communication performance. In this study an evaluation conducted to Secure Mobile Sink Node location using Dynamic Routing Protocol (SMSNDRP) into two phases: routing generating and routing evaluation. In routing generating phase, the best path is selected based on the minimum distance between (Cluster head CH and mobile Sink Node SN) and highest CH residual energy. While in routing evaluation phase, the quality of each path is measured via creating five scenarios, one for static SN and four for mobile SN. The NS 2.35 simulator is used to implement the routing evaluation phase. The main aim of this study is proposes a technique to specify the best quality route that meets the QoS constraints for all SMSNDRP generated routes, in order to choose the best route for routing data to the SN, it must have the highest packet drop ratio, average throughput and less end to end delay that achieved better performance than other routes in the network.
