Wireless sensor network consisting of a large number of small sensors with low-power transceiver can be an effective tool for gathering data in a variety of environment. The collected data must be transmitted to the base station for further processing. Since a network consists of sensors with limited battery energy, the method for data gathering and routing must be energy efficient in order to prolong the lifetime of the network. LEACH[4] is an elegant energy efficient protocol to maximize the lifetime of sensor network. In this paper, we presented DEED, a distributed energy efficient protocol with data fusion technology. DEED clusters nodes into groups and builds routing tree among cluster heads, among which only the root node communicates the base station directly. Simulation results show that DEED performs far better than LEACH.
