Resource coordination in Wireless Sensor Networks by combinatorial auction based method

Wireless Sensor Networks (WSN) consists of small sensor devices with sensing, processing and communication capabilities. Sensor nodes are operated by batteries. As the replacement of these batteries are not practical, this network is very much energy sensitive. Resource coordination is an important issue to make this system energy efficient. Sensor nodes can be applied in various applications. Object tracking, routing, event detection are some common applications in WSN. These application needs to perform some tasks like sensing, transmitting, sleeping, receiving etc. At each time step, the sensor nodes need to perform one task based on its application demand. Scheduling of these tasks is very important aspect for WSN in order to coordinate the resources. In this paper, an effective market based method is proposed for resource coordination in WSN. At first the description of the problem is presented then the combinatorial auction based method is proposed. The simulation results show the efficiency of the proposed method comparing with other existing methods. © 2012 IEEE.
