MAC Protocol with Low Energy Consumption in Wireless Sensors Network

Medium Access Control (MAC) protocols must perform the functionality required by the application while utilizing the limited resources available on sensor nodes. Limited energy resources place strict limits on the operations that a sensor node may accomplish and differentiate sensor networks from other networks. Application and protocol designers must utilize the hardware resources of the sensor nodes judiciously to conserve energy and prolong the network lifetime. Especially, when the sensors network becomes accessible from internet, where the end users can monitor, configure and send special requests to the sensors nodes. In this paper we present a new solution to improve collision avoidance and optimize the energy consumption. The simulation results show that the life time of sensor node has been improved.
