Many wireless sensor network (WSN) applications require join of sensor data belonging to various sensor nodes. For join processing, it is important to minimize the communication cost since it is the main consumer of battery power. In this paper, we introduce a parallel join technique for sensor networks. A WSN consists of many independent sensor nodes and provides a natural platform for a shared-nothing architecture to carry out parallel processing. The proposed parallel join algorithm is baseddoi:10.1016/j.aasri.2013.10.051 fatcat:tliavm5qzjaf7joltp6jzzceea
