In the recent advance in science and technology, the communication system has been marching towards quick development. Wireless sensor network is one of the important blocks for communication. The major limiting factors in wireless sensor network are power consumption requirements, life time of network, data integrity and data confidentiality. Data aggregation is a very critical strategy in wireless sensor network. Data aggregation is a methodology of gathering and accumulating the message information in a vital effective way, so that life time can be expanded.
