基于移动Agent的LEACH协议的研究与改进

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。

Improvement of LEACH based on Mobile Agent

Preventing sensor node from dying too early and prolonging the lifetime of the network is the most important goal for the design of routing protocol in wireless sensor networks. Based on hierarchical routing protocol LEACH, a new MA-LEACH（Mobile Agent LEACH） routing protocol is proposed in this paper, into which the Mobile Agent computing model is introduced in order to avoid transmitting a great number of sense data, and the sense data is processed at the sensor node by Mobile Agent. The simulation results indicate that MA-LEACH is more effective than LEACH in the aspects of reducing node energy consumption and prolonging the network lifetime.
