摘要

为了在无线多媒体传感器网络WMSNs通信中提供QoS支持，研究了WMSNs最小能耗实时路由算法问题。首先，定义了数据融合的概念及其在路由设计中的作用，在此基础上设计了一个最小能耗实时路由算法LERTR，用于构造WMSNs最小能耗实时路由树。该算法首先使用ADH算法生成一棵最小能耗路由树；若时延不满足要求，则通过合并最小时延路径来产生一个满足时延约束的路由树。仿真实验表明：LERTR算法生成的路由树在保障时延约束的情况下，具有很好的能耗代价性能。

Abstract

In order to provide real-time communication in wireless multimedia sensor networks (WMSNs)

the QoS supported routing algorithm is addressed. Theoretically

data aggregation is defined and its advantages in QoS routing are introduced. Based on it

a least energy realtime routing algorithm (LERTR) is presented to construct the delay-constrained routing tree in WMSNs. In LERTR

a least energy routing tree is constructed by average distance heuristic (ADH)

and then

if the path delay can't meet the delay upper bound

a shortest delay path which is computed by Dijkstra's algorithm will be merged into the existing routing tree to meet the delay upper bound. Finally

the simulation results verify the correctness of the algorithm in some degree.
