Wireless Sensor Networks (WSN) in the context of the current project are spatially distributed sensors used for monitoring environmental conditions. Two major considerations in a WSN are lifespan maximization and security improvement. This project presents a routing protocol that successfully addresses both of these considerations. The use of a non-uniform energy deployment strategy improves the network lifespan and message delivery ratio under similar energy resources. The proposed protocol also improves network security by creating unpredictability in the routing path using a random walk strategy. Additionally, it provides source location privacy to prevent routing traceback attacks and jamming. Simulation results confirm the advantages of the proposed routing strategy as compared to existing standard routing protocols.
