Hop-by-hop data aggregation is a very important technique for reducing the communication overhead and energy expenditure of sensor nodes during the process of data collection in a...
Abstract— Securing broadcast communication over sensor networks is an important research challenge. In general, broadcast communication has two important metrics: security and re...
We have developed a self-healing key distribution scheme for secure multicast group communications for wireless sensor network environment. We present a strategy for securely distr...
