Mobility and its impact on performance of AODV and DSR in mobile ad hoc network

摘要

In recent years the rapid development in telecommunication technologies leads to a non linear growth in the number of users of mobile electronic gadgets accessible to a communication network. These electronic gadgets are nothing but the nodes of the MANET (Mobile Ad hoc Network) and thus the mobility of the nodes effects a much the performance of the network. A change in mobility can be meant as the change in speed of node during motion in the network or pause time at different points during its motion between a source and destination point in the network. Due to change in mobility link between neighbors nodes can break a number of times as a result of which the performance of a network may be hampered. Also a number of packets may be dropped at different layers of the network. This paper describes a detailed analysis of performance affected due to change in mobility. The parameter describing the reason of variation in performance are (1) number of link breaks and (2) number of packet delivered. (3)End to end delay. The simulator we have used in our work for the calculation of performance matrices is GLOMOSIM. The performance comparison has also made considering two types of routing protocols AODV and DSR.
