传感反应网络中单反应节点任务分配问题的研究

Research on the Allocation of Single-Actor Tasks in Wireless Sensor and Actor Networks

无线传感反应网络由大量资源受限的传感节点和少量资源丰富的反应节点通过无线通信自主形成的。其中,传感节点负责收集外界的事件信息,而反应节点依据传感节点探测到的信息做出决策,并对外界做出响应。本文主要研究WSANs中单反应节点任务分配的问题,并提出集中式和分布式两种算法,最后用J-Sim评估两种算法的性能。

Wireless sensor and actor networks （WSANs） are composed of a large number of sensors and a small number of （mobile） resource-rich actors. Sensors gather irformation about the physical phenomenon while actors make decisions, and then perform appropriate actions upon the environment. The paper studies the allocation of single-actor tasks in WSANs, and proposes two algorithms： a centralized and a distributed algorithm. Finally the algorithms are evaluated in JSIM.
