中文摘要：

结合无线传感器网络面向应用的实际需求，提出一种新颖的能量感知型无线传感器网络跨层协议ECLC，并给出了实现过程和仿真结果。基于重点关注热点能耗的策略，综合WSN在能量高效、可扩展性、服务质量等方面的不同要求，设计了简单可靠、易于实现的跨层式WSN网络协议。仿真结果表明：ECLC协议在传感器网络系统层面较好地改善能量消耗的有效性和均衡性，因而避免了网络中热点的过早出现，延长了整个网络的生存期。

英文摘要：

This paper proposes a new type of energy- aware cross- layer protocol for Wireless Sensor Network（WSN）, and gives the realization process and simulation results. From the actual application of WSN, integrating energy high - efficiency, expandability,quality of service and other different requirements, this paper designs the protocol, which focuses on the strategy of hotspot. The simulation result shows., this protocol can enhance the efficiency and balance of energy consumption in terms of sensor networks system,therefore,the premature emergence of hot spots is avoided and the life span for the whole network is prolonged.
