Energy aware diffusion in Wireless Sensor Networks

Wireless Sensor Network is a network of hundreds or thousands of Sensor Nodes. These Nodes communicate with each other with short range radio signals. These nodes are small in size and have very limited battery power. The focus of the researchers is always on developing the routing protocols having the low power consumption to enlarge the life time of the network. In this paper we have proposed Energy Aware Diffusion for wireless sensor networks which is based on directed diffusion. In Directed Diffusion The path selection done by the Sink Node is based on the quality of the path (i.e. the path will be selected based on the higher data rate). In our approach the sink will select a path which will require minimum energy to send the data from source to sink. The experimental results shows that the proposed algorithm works better in terms of network life time, average end to end delay and energy savings.
