Energy aware adaptive directed diffusion algorithm of wireless sensor networks
Qi Hao, Fubao Wang, Bingxiang Wang · 2011
For the unbalanced energy consumption problem in Directed Diffusion and Energy Aware Directed Diffusion in heterogeneous networks, we propose the EAADD: Energy Aware Adaptive Directed Diffusion for Wireless Sensor Networks. This protocol changes the way of building reinforced path : flrst, we consider about the correlations of node available energy between adjacent rounds, then we use the adaptive algorithm to choose next hop node which is more durable. That means the node could forwards more package than other nodes in the same status. EAADD is a distributed protocol and could used in large scale environment for wireless sensor networks. Simulation results show that EAADD could not only prolong the life of single node, but also spread energy consumption more evenly throughout the network.
