Recently wireless sensor networks featuring direct sink access have been studied as an efficient architecture to gather and process data for numerous applications. In this paper, w...
This paper proposes iPTT, a peer-to-peer Push-to-Talk (PTT) service for Voice over IP (VoIP). In iPTT, a distributed and mobile-operator independent network architecture is presen...
Efficient and robust metacomputing requires the decomposition of complex jobs into tasks that must be scheduled on distributed processing nodes. There are various ways of creating...
We consider the problem of selecting a subset of p out of n sensors for the purpose of event detection, in a wireless sensor network (WSN). Occurrence or not of the event of intere...
