一种新的移动传感器网络部署及管理机制

A New Mechanism of Deployment and Management in Mobile Sensor Network

在移动传感器网络中,传统的基于虚拟力的部署方法通常采用牛顿运动定律计算节点的位置移动.该方法能够实现移动传感器网络的自动部署,但也将简谐振动带入到网络中,使一些节点在达到平衡位置后无法立即停止,从而消耗了传感器大量能量.通过重新定义应用于移动传感器网络中的运动定律,提出了Force-based算法,使节点的运动只与受力相关,较好地解决了该问题.模拟实验表明,该部署方法可以较好地完成节点的自动部署,扩大了覆盖率,降低了能量消耗.

In the field of mobile sensor network （MSN）, conventional deployment algorithm based on virtual force introduces Newton＇s law of motion into MSN. Although the self-deployment of MSN can be implemented, it also brings oscillation into MSN making some nodes impossible to stop quickly even if the nodes have reached their balance state. This problem leads to energy consumption in vain. By redefining laws of motion in MSN, a new Force-based algorithm is proposed. With this the motion of node is only determined by force. Simulation results showed that this deployment algorithm is effective and exhibited excellent performance in coverage and energy conservation.
