摘要/Abstract

摘要： 在WSN网络中引入执行器节点构成WSAN网络,并依据WSAN网络特性提出一种新的协作路由协议——基于动态分簇的角度转发路由协议AFRPDC(Angle Forwarding Routing Protocol base on Dynamic Clustering)。AFRPDC协议由2部分算法组成:基于接收信号强度RSSI(Received Signal Strength Indication)的动态分簇算法BRCA(Based on RSSI Dynamic Clustering Algorithm)和角度转发路由协议AFRP(Angle Forwarding Routing Protocol)。BRCA算法保证传感器节点形成较为稳定的拓扑,实现传感器节点与簇头节点的协作；AFRP协议利用簇头节点的角度信息转发事件报告,实现簇头节点与执行器节点的协作通信。仿真结果表明,AFRPDC协议中节点分簇有较好的稳定性,同时AFRPDC较基于链路状态分簇的定向扩散协议DDLSC在降低平均时延和节点能耗方面有更好的表现,可满足WSAN网络对实时性、可靠性和低能耗的要求。

Abstract: Wireless sensor and actor network (WSAN) was derived from WSN by adding actor nodes which would make decisions and executive scheduled tasks,and a new cooperative routing protocol based on the characteristics of WSAN network was proposed—the angle forwarding routing protocol based on dynamic clustering (AFRPDC),which consists of a RSSI-based dynamic clustering algorithm (BRCA) and an angle forwarding routing protocol (AFRP)．The cluster-head election was improved and the stable topology was constructed in BRCA．Then,event data was transmitted directly to cluster-head nodes by sensor nodes using peer-to-peer communications,and was reported to actor nodes by cluster-head nodes with AFRP．Next-hop nodes were selected using angle informations and multi-path routings were found from source cluster-head nodes to actor nodes．The routing path with minimum delay was established when transfering event data．The simulation results show that the proposed cooperative routing protocol has better perfor-mance than the directed diffusion protocol based on link-state clustering (DDLSC) in reducing the latency and power consumption,and prove that the protocol could meet the requirements of real-time,reliability and low energy comsumption in WSAN.
