Aggregation capacity of wireless sensor networks: Extended network case
—A critical function of wireless sensor networks (WSNs) is data gathering. While, one is often only interested in collecting a relevant function of the sensor measurements at a s...

Analytical modeling and mitigation techniques for the energy hole problem in sensor networks
In this paper we investigate the problem of uneven energy consumptions in a large class of many-to-one sensor networks. In a many-to-one sensor network, all sensor nodes generate ...
