Improvisation of MAC Protocol for Wireless Sensor Network

Wireless sensor networks are collection of sensor nodes connected via wireless LAN links. The information gathered at sensor node is propagates in the form of radio signal to control room via multi hop communication. In the networks, many sensors where lying in same channel to pass message, so as well as minimize the power efficient and delay for sensor networks. An Efficient Medium Access (MAC) protocol is critical for the performance of a Wireless Sensor Networks (WSN), especially in terms of energy consumption. IMAC is a Time Division Multiple Access (TDMA) scheme that extents the common single hop TDMA to a multi hop sensor network, using a high-powered base station to synchronize the nodes and to schedule their transmission and receptions.
