摘　　要：在无线传感器网络中适当地部署少量的异构传感器节点能够有效地延长网络寿命,提高网络的可靠性。本文主要研究无线传感器网络中异构节点的部署问题,提出了基于选址问题的异构节点部署算法,以优化无线传感器网络中异构节点的数量和位置。与其它算法相比,该算法对无线传感器网络的拓扑结构没有特定的要求,可以支持随机部署或人工部署的各种传感器网络,最后还给出了该算法的仿真测试结果。Placing few heterogeneous nodes in wireless sensor network is an effective way to increase network lifetime and reliability. We address the deployment problem of heterogeneous wireless sensor networks. We present an algorithm to decide how many and where heterogeneous nodes should be deployed in the wireless sensor network. The core algorithm, based on the locations of all sensor nodes, can optimize placement of heterogeneous nodes in an arbitrary sensor network. Finally, the evaluation results of this algorithm are shown in this paper.
