Distributed energy aware routing protocol for large-scale wireless sensor network

Routing in wireless senor network is different from in other networks, since the nodes' limited energy supported by batteries and the design of routing for wireless sensor network is related to its application. In this paper, we propose a distributed routing protocol for called DHEIRP(distributed hop-based energy iteration routing protocol), which is typically for large-scale sensor network. DHEIRP chooses the hop counts, RSS(received signal strength) and residual energy level as metrics, minimizing energy consumption and balancing nodes' energy. From numerical simulations, we prove that DHEIRP excels GBR and HBRRP in term of balancing load of the nodes and extending network lifetime.
