摘要
介绍了无线传感器网络移动代理的概念和特点,分析了TinyOS主动消息通信模型基本原理,进而提出了一种移动代理变种在TinyOS中的实现机制.该变种把代码空间和数据空间区分传输,利用无线信道的广播特性极大地减少了发送代码空间的能量消耗.仿真结果表明,在节点数目较多的情况下,移动代理变种模式的网络性能比传统的客户端服务器模式更加优越.
The concept and the characteristic of mobile agent in wireless sensor network are introduced, and the basic principle of active message communication model is analyzed in TinyOS, Furthermore, scheme to realize mobile agent variation in TinyOS is provided. The simulation results show that, network performance in mobile agent variation mode is better than the one in traditional client/server mode when number of nodes is much.
