Sensitive Energy Efficient- MAC Protocol in Wireless Sensor Network

ABSTRACT A Sensor network is a technique where many distributed sensor devices with a sensing system collect information. These nodes are normally deployed in an adhoc manner, operate in distributed way. Generally the sensors nodes are battery powered, and it is often not feasible recharge them. This makes the problem of conserving energy at individual sensor nodes challenging. This paper introduces S-MAC protocol used for WSNs and proposes SEE-MAC, a Medium-Access Control protocol designed for Wireless Sensor Networks. SEE-MAC uses a little advanced technique to reduce energy consumption. A new protocol is proposed to improve the energy efficiency, latency and throughput for WSNs. A modification of the protocol is proposed to reduce the need for some nodes to live awake longer than the other nodes which improves the energy efficiency, latency and throughput and therefore increase the life period of a wireless sensor network.
