Mathematical Modeling and Simulation of Wireless Sensor Network Coverage Problem

The research on wireless sensor networks has achieved a lot in recent years and some of the results have been put into practical applications, but with increasing demand requirements for networks, many old new problems need to be solved urgently. In this paper, data topology optimization algorithm based local tree reconstruction heterogeneous is proposed transmission that are easily affected by external instabilities. This network can accomplish better transmission; firstly, nodes divided different layers according hop count network, certain proportion relay selected layer nodes; then, initial energy set nodes, since packets sizes, corresponding aggregation coefficients used paper actual during finally, dynamically updated real time operation extend lifetime nodes. simulation verify evolution effectively extends improves utilization establishes modified least-squares target localization model achieve accurate 3D targets scenes proposes an optimal base station node selection strategy spectral clustering using location distribution information space. show error terminal coordinates calculated smaller than coordinates, other existing algorithms same data.
