Error Free Wireless Sensor Network with an Efficient Data Collector

Wireless Sensor Network consists of a sink and a number of stationary nodes. In WSN, there are two major problems namely, limited energy and fault occurrence. In the proposed system, to decrease the energy consumption, the nodes are randomly deployed over an area. This area is divided into NxN square grids. At the center of each grid, a Mobile Sensor is placed, which moves in a criss-cross manner so that all the nodes in the region comes within its range and can effectively collect the data. Routing is performed among the mobile sensors and the collected data is uploaded to the sink. The lifetime of the network is calculated and the efficiency is found. When compared to the normal deployment of the network without any mobile sensors, the energy consumption is less and lifetime is more. For addressing the fault occurrence issue, we use various fault prediction methods for both predictable and unpredictable faults such as out-of range prediction, habitat hazard and e-scan method. When a node is found to the failed node using the Hybrid swarm optimization method.
