Visualization of the Constrained Coverage of Mobile Sensor Networks Based on GML

Mobile sensor nodes should be well deployed so that they maximize the area coverage with the constraint that each node has at least K neighbours, where is a user-specified parameter. The MSNS (mobile sensor node simulator) designed in this paper visualizes the real map objects created by a GML, and the movement of each sensor node which autonomously extends the constrained coverage introduced by. We explain how each sensor node avoids obstacles in our simulator, while extending the rate of the constrained coverage. And then, we describe the design of MSNS and simulation results. From a user, MSNS takes two parameters: the number of mobile sensor nodes deployed and the constraint parameter K. It calculates and shows the coverage rate and the average number of neighbour nodes in a real-time manner.
