A study of energy efficient transmission protocol in wirless sensor network

WSN has collection of sensor nodes, generally these sensor nodes tiny in size, less power and less cost and multifunctional in nature. Different routing protocols aim is to optimize lifetime and energy of the sensor networks. A lot of routing protocol in wireless sensor network also current senerio dependent, which gives the plateform to develop variety of protocol, Basically according to the communication energy is broadly classified into two types 1. Direct Approach and 2. Hierarchical Approach. Wireless sensor network have architecture copout between energy and communication overhead i.e the backbone of routing technique. In this paper we explained different type of protocols and a different senerio in the wsn.
