Evaluation of Network Lifetime by Multipath Routing Protocol for WSN
Sandeep Kumar Singh, Chetana Asbe · 2023
Network lifetime is the amount of time a wireless network remains operational before it must be repaired or replaced. Extended network lifetime is a major challenge in wireless sensor networks (WSNs). To extend the lifetime of a wireless sensor network, multipath routing protocols have been proposed and implemented. These protocols employ multiple paths for data transmission, in order to enhance the network throughput, reduce packet loss and extend network lifetime. In this paper, we evaluate the impact of multipath routing protocols on the overall network lifetime. We consider three different multipath routing protocols: Geographic location based routing, Deluge and Thor. We conduct extensive simulations to compare the performance of these protocols in terms of network lifetime. Simulation results show that Geographic location based routing, Deluge and Thor all extend the network lifetime compared to a single path routing. However, Thor can significantly enhance the network lifetime in all scenarios. We also analyze the energy consumption, packet loss and throughput of each protocol and demonstrate that multipath routing is an effective technique to enhance the network lifetime while still providing good performance.
