| 摘 要： | 在基于无线传感器网络的普适计算环境中,由于节点的移动,使得无线传感器网络中消息分发机制不再适用.在分析消息分发的影响因素的基础上,利用虚拟网格实现了寻找最短路径作为消息分发路径,同时讨论了此机制中面临的源节点移动时出现的新问题,并通过仿真分析验证了提出的分发机制的可行性.

| Abstract: | In the pervasive computing environment based on wireless sensor networks,as a result of nodes moving,the message distribution mechanism is no longer applicable.After analyzing the distribution of message influencing factors,it was found that the virtual grid can be used as the shortest path for message distribution.In the article,the new problems were also discussed that this mechanism will face when the source node moves.Therefore with simulation analysis,the feasibility of the distribution mechanism proposed by this paper was verified. |
