Optimal Deployment

In sensor networks, a reasonable distribution of sensor nodes is an important role for the improvement of sensor ability, information collection ability and network survival. For multilayer mobile sensor network, a tree-based deployment optimization scheme was proposed and better sensor coverage could be achieved by topology adjustment utilizing mobility of sensor node. Sink nodes complete mobile positioning of S nodes based on rectangle division method and bounding box algorithm, and achieve the distribution optimization of S nodes by establishing extending-tree of Sink node as the center. Results show that the location error ratio reduces with the increase of Sink nodes. Compared with initial random deployment network, the network coverage ratio after optimal deployment significantly enhances, which effectively improve the coverage sensor range of overall network.
