The WSN Energy Efficient Protocol Based on Adaptive Mechanism of Sleep

ABSTRACT

In view of node energy limitation in the wireless sensor network, efficient energy saving strategy has become one of the hot spots in the wireless sensor technology. Through the analysis of the energy efficiency solution of wireless sensor network in each layer, put forward a kind of wireless sensor energy efficient protocol based on adaptive sleep mechanism. The scheme according to the residual energy storage, location and degree of adjacent nodes load, using variable duration of sleep mechanism to choose forward grouping way. Compared with the random transmission scheme based on the geographical position, the given scheme can save the network node energy greatly and balance the network energy consumption effectively. Therefore, this scheme can improve overall network life significantly.
