传感器网络中的设备逐渐增多使得地址的管理和维护变得复杂,已有的地址配置协议Quorum和MANETConf方法利用分布式的方法能够完成地址的自适应配置和管理,但其在开销以及配置速度方面逐渐制约了网络的应用和发展。采用定位技术,对GPS同步信息解码获得本地地理位置信息,从而辅助节点进行地址管理维护等功能,加快配置速度、减小传统的配置方法中由于相邻簇备份或者泛洪操作所带来的巨大开销。最后,基于OPNET仿真软件搭建仿真平台,验证该方法的有效性。
The address management and maintenance have become a more and more important issue as with the rapid development of the wireless sensor network.There are two typical address configuration protoeol(i.e.,Quorum,MANETConf) can be competent for that works adaptively by utilizing distributed method.However,the network applications are constricted by the message overhead and the configuration time of the above two approaches.In this paper,a location-based method is proposed to assist the address configuration.The position of each mobile node can be obtained by decoding the GPS synchronization channel, which can improve the performance of the configuration time and the message overhead.A simulation platform is also constructed to verify the efficiency of this method.
