Intelligent Security System Based on Wireless Sensor Networks

In this paper, we present a Intelligent security system based on wireless sensor networks to solve the problems existed in the wire security systems such as difficult to extend and severe load-consumption. The system adopts hybrid topology structure based on cluster. A modified cluster head selection algorithm based on random waiting is adopted. The simulation results show that the energy cost in setup phase of the sensor nodes is exponentially reduced using the modified cluster head selection algorithm as the monitoring area increases when comparing with LEACH algorithm. The wireless micro-sensor can be scattered to the surroundings that human unable enter. Then the sensor nodes will self-organize into networked security system and realize monitor task. The system also can be used to forest fire proofing and environment pollution inspection after modification.
