能量和移动距离有效传感器网络部署

作为新兴的无线传感器网络具有十分广阔的应用场景,包括军事、环境监测、目标追踪、科学观察和预报等领域.然丽在实现各种网络协议和应用系统时,存在着一些现实约束.比如传感器节点体积微小,通常有能量十分有限的电池;但同时传感器节点个数多、分布区域广、部署区域环境复杂,通过充电或更换电池的方式来补充能源是不现实的,因此节能是无线传感器网络研究的重要目标.无线传感器网络的能量消耗直接决定了网络的使用寿命,通过有效配置传感器网络节点可以合理覆盖感知数据区域,延长网络的生命周期.采用已有传感器感知模型和虚拟力法(Virtual Force Algorithm),假设节点为势力场中的粒子,根据节点间力的作用部署节点,通过改进的虚拟力算法获得均匀的网络部署效果,达到能量有效的目的,使得网络均匀覆盖、延长网络的使用寿命.

Deployment of Energy and Distance Efficient Sensor for Wireless Sensor Networks

Wireless Sensor Networks(WSNS) as an emerging technology will have a wide range of potential applications including military surveillance,environment monitoring,object tracking,scientific observiation and forecasting and etc.However,there are several practical constraints in implementing various protocols and application systems.Power is identified as one of the most expensive resources.Due to the large scale and the remote or hostile environment,it is impractical to recharge or replace power supply.Since t...
