摘　　要：实时需求是传感器网络应用于时间敏感领域的一个重要议题.提出一种新颖的受限等效时延(CED)的概念,把端到端的时延需求划分成路径上每段链路的CED的总和.每个节点可以根据CED独立选择下一跳节点,因此简化了路由寻找过程.仿真结果表明这种路由协议在保证高连通率的前提下可以提供较低的能量消耗和较短的端到端时延.In the time-critlcal scenarios,delay requirement becomes a key problem in the design of sensor networks. A novel concept of Constrained Equivalent Delay （CED） is put forward in this paper. It separates the end-to-end delay requirement into the sum of point-to-point CED. Each intermediate node can independently decide its next forwarding node according to each CED, so it will greatly simplify the route discovery process. The simulation results show the routing protocol is effective on the performance of energy consumption and end-to-end delay compared with some other routing protocols.
