Barrier Coverage with Mobile Sensor Network

In order to save the mobile sensor network energy and improve the barrier coverage with mobile sensor network to adapt to the environment. The virtual force principle is applied in low power RF (Radio Frequency) wake-up mobile sensor nodes and obstacles. Some of sensor nodes are in the state of work, the others are dormant. When the sensor network is damaged, the dormant sensor nodes can be waked up timely and mobile to the damage place to restore the barrier coverage. Analysis by simulation, it can effectively save the network energy consumption, improve the service life of the network and the network capacity to adapt to the environment.
