WSNs by using mobile nodes

In particular, mobile nodes are effective for adequate field coverage: however, appropriate node movement is critical. In addition, mobile nodes with wireless charging devices can charge the batteries of other nodes. We formulate the problem to extend lifetime and maintain field coverage by determining the positions of mobile nodes that can cover the field effectively and charge the batteries of other nodes simultaneously.

Coverage: In WSN, each sensor node is given a glimpse of the environment. This follows are limited in range and accuracy (Figure 1), it can only include a limited physical area of environment. Therefore, coverage is also an important design parameter in WSNs. Each node receives a local view of its environment, limited by the scope and accuracy of it. the coverage of a large area composed by the union of a number of smaller insurance. Connectivity: Most of the high density of WSNs sensor, thus preventing the isolation of the nodes.
