无线传感器网络中路由协议最重要的设计目标是避免节点过早死亡,延长网络生存时间。文中在原有层次式路由协议LEACH的基础上,提出了一种新的MA-LEACH(Mobile Agent LEACH)路由协议,MA-LEACH中引入了移动Agent计算模式,避免了大量的感知数据在网络中传输,由移动Agent移动到感知节点进行本地处理。仿真实验表明,MA-LEACH比原有LEACH协议在降低节点能耗,延长网络寿命等方面上有了显著提高。
The most important design goal of routing protocols in wireless sensor networks is to avoid premature death of nodes and prolong network lifetime. In this paper, based on the original hierarchical routing protocol LEACH, a new routing protocol MA-LEACH (Mobile Agent LEACH) is proposed. The MA-LEACH algorithm is introduced to reduce the number of perceptual data transmitted in the network , The mobile agent moves to the sensing node for local processing. Simulation results show that MA-LEACH has a significant improvement over the original LEACH protocol in reducing node energy consumption and extending network lifetime.
