Optimizing lifetime of a wireless sensor network covering moving targets

Abstract In this article, the problems studied are to optimize life of network sensors covering mobile targets by minimizing energy consumption network. Indeed, wireless sensor networks have received particular attention in recent years, as their applications common today, such vehicle tracking or battlefield monitoring. a network, battery plays an important role. The function depends on life. Replacement batteries becomes impossible once deployed remote unattended location. A set randomly placed monitors moving area. Each has limited lifetime and two states: Active Inactive. An active can monitor its monitoring sub-area at necessary cost. To model these problems, we use mathematical based linear programming with mixed integer variables. AMPL is used formulate MINOS for resolution numerical results allowed obtain adequate activation scheduling improving lifetime.
