—The core functionality of a wireless sensor network (WSN) is to detect deviations in expected normal behavior and report it to the sink. In this paper, we propose TRACK — a no...
Abstract—Opportunistic wireless channel access by nonlicensed users has emerged as a promising solution for addressing the bandwidth scarcity challenge. Auctions represent a natu...
Traditionally, specific telecommunications services were essentially confined to certain types of networks; e.g., television over broadcast networks or cable and voice service ove...
Methods for node localisation in sensor networks usually rely upon the measurement of received strength, time-of-arrival, and/or angle-of-arrival of an incoming signal. In this pap...
We investigate the problem of maximizing the lifetime of wireless ad hoc and sensor networks. Being battery powered, nodes in such networks have to perform their intended task und...
