事件驱动型传感器网络地址分配算法研究

摘要

无线传感器网络中的地址分配是应用的前提,但目前研究相对较少.分析现有的无线传感器网络地址分配协议,提出了一种基于最小跳数的按需分配的地址分配算法,在网络初始阶段构建最小跳数,当节点监测到事件根据最小跳教建立与Sink节点的通信,获取事件节点的通信地址.理论分析及仿真结果表明,该算法降低了协议自身的通信开销,满足了无线传感器网络中通信节点资源极其稀少和低功耗的需要.%The research on the address allocation for wireless sensor network is seldom,particularly in the network based event-driven.The representative address allocation protocols are analyzed,and a minimum Hop-Count Address Allocation(HCAA) is pro-posed:During the boot up phase each node gets their minimum hop-count.When the node detects their interesting event,it can build the communication with sink node by the hop-count,and get its communication address.The analysis and simulation vali-date that the method reduce the overheads of the communication and meets the constraints of low energy consumption and limits processing power in wireless sensor network.
