基于数据卸载策略的能量优化方法在移动代理路径规划中的应用

Application of mobile agent itinerary planning based on data offloading strategy of energy optimal method

提出了移动代理数据卸载策略,对无线传感器网络中现有移动代理规划路径进行优化,根据卸载规则决定是否将数据分组分离通过优化的卸载路径传递,卸载数据的移动代理通过原路径访问数据源节点。使用移动代理经典算法IEMF(itinerary energy minimum for first-source-selection)进行大量的仿真实验,结果显示,提出的数据卸载策略能有效地解决数据源节点能量消耗过快的问题,延长数据源节点的生存期。

A data offloading strategy for optimizing itinerary planning of MA （mobile agent）was proposed. When MA visits source nodes based on data offloading strategy, it decides whether to transfer data package via optimized offloading itinerary and MA（mobile agent） visits data source nodes via conventional itinerary. Based on considerable simulations with the representative MA itinerary planning, i.e. itinerary energy minimum for first-source-selection （IEMF）, it verifies that the problem of excessive energy consumption from source nodes can be efficiently solved and the lifetime of source nodes is prolonged.
