| 摘 要： | 无线传感器网络(WSN,wireless sensor network)中,基于代价的能效路由协议(CEERP,cost-based en-ergy-efficient routing protocol)通过计算与比较代价函数值可以找到具有优异性能的路由。在前期研究提出的CEERP协议基础上,对该协议的代价函数、能耗和时延性能进行了分析,确定了首个节点死亡前系统所能完成的通信轮数的上下限以及时延计算公式。在采用能耗与时延的乘积作为性能评价标准的前提下,对多种同类协议的性能进行了比较与讨论,并在节点稀疏布署和非理想信道的情况下分别对CEERP的性能进行了进一步仿真。结果表明,CEERP协议在能耗与时延的综合性能上相对于其他同类协议具有很大的优越性。

| Abstract: | In CEERP(cost-based energy-efficient routing protocol),the routing which had superior performance in WSN(wireless sensor network) could be found through calculating and comparing the cost function values.The cost function,energy consumption and delay performances of the previously proposed protocol,CEERP,were analyzed.The lower-and upper-bound of communication rounds performed by the WSN system and the calculation formula of delay were derived.The performance of various similar protocols was compared and di... |
