Data gathering is a common but critical operation in many applications of wireless sensor networks. The innovative techniques that improve energy efficiency to prolong the network ...
Due to the long propagation delay and high error rate of acoustic channels, it is very challenging to provide reliable data transfer for time-critical applications in an energy-ef...
Abstract. In this paper, we propose a new medium access control protocol for wireless sensor networks, named LE-MAC (Latency and Energy aware MAC) that aims to minimize data delive...
Energy efficiency is one of the most critical issues in the design of wireless sensor networks. Observing that many sensor applications for object tracking can tolerate a certain d...
In this paper, we propose a novel, cluster-based energy balancing scheme. We assume the existence of a fraction of “strong” nodes in terms of abundant storage, computing and co...
