Data Aggregation In Wireless Sensor Networks Using Mobile Data Collector

P.Saranya

Wireless sensor networks (WSNs) have emerged as a new information-gathering paradigm in a wide range of applications, such as medical treatment, outer-space exploration, battlefield surveillance, emergency response, etc. Large-scale wireless sensor networks which introduce mobility into the network is an new data-gathering mechanism. A mobile data collector, called an M-collector, mobile robot or a vehicle equipped with a powerful transceiver and battery, working like a mobile base station and gathering data while moving through the field. Multiple M-collector are used for the data-gathering algorithm where multiple M-collectors traverse through several shorter subtours concurrently and sensing data collected from sensors are forwarded to the nearest M-collector to the data sink. It mainly focus on the problem of using Multiple M-collector the cost and energy. Energy consumption is reduced by using the backup device selection of node from each subgroup of sensors. Backup device aggregating the data from each sensors in a multi-hop communication with the help of single M-collector. Simulation results shows that the proposed data-gathering algorithm can greatly shorten the moving distance of the M-collector and energy. And also it can significantly prolong the network lifetime compared with a network with static data sink.
