An energy-efficient scheme by cross-layer for wireless sensor network

In the area of wireless sensor networks, achieving minimum energy consumption is a very important research issue. At present, a lot of energy efficient protocols have been proposed, mostly based on a layered design approach, which means that they are focused on designing optimal strategies for single layer only. In this paper, we present a cross-layer scheme by analyzing the routing and the scheduling. Through averaging the energy the nodes consumed, reducing the idle listening and minimizing collision, we could achieve the purpose of prolonging the lifetime of wireless sensor network. Through simulation study using NS-2 simulator, we evaluate the performance of the presented strategy and prove its substantial performance gains.
