Performance Analysis of Modified AODV Routing Protocol With Lifetime Extension of Wireless Sensor Networks

Abstract

Amalgamation of Re-Charging and Load Balancing are introduced here to overcome the problem of quick battery energy depletion and jamming in Wireless Sensor Networks. The primary approach (Re-Charging) is to maintain the desired energy level at each node in the network. The second method guarantees jamming-free communication in the network. To maintain the required energy level of the nodes, the SenCar visits the chosen anchor point along the pre-defined trajectory. At the chosen point, SenCar tests all the nodes within its coverage and re-energize all the nodes that have the energy level below the threshold value (3 Joules). Then, the SenCar moves on to the next anchor point and so on until the pre-defined trajectory completes. Finally, the implementation of the proposed mechanism proves the performance enhancement of Wireless Sensor Networks in terms of Throughput, Energy Level, and Packet Delivery Ratio.
