Power Optimization in MAC Protocols for WSN

Wireless Sensor Network (WSN) find its role in applications like smart building, urban surveillance, animal farming etc. The challenge in WSN is to reduce energy consumption and increase the network lifetime. In this work, we have proposed a new technique for MAC protocol to control a few network parameters like jitter, energy, throughput etc. Basic 802.11 MAC and P-MAC are simulated using NS-2.34 and the performances are compared. Power controlled MAC (P-MAC) perform better in terms of energy, throughput. Thereby the network life time is increased and efficient data transmission takes place.
