In this paper, we present a Gaussian mixture model based approach to capture the spatial characteristics of any target signal in a sensor network, and further propose a temporally...
Event boundary detection is in and of itself a useful application in wireless sensor networks (WSNs). Typically, it includes the detection of a large-scale spatial phenomenon such ...
—Fault tolerance techniques have been widely used in wireless sensor networks. Base station placement to maximize the network lifetime has also been well studied. However, limite...
We study the multicast problem in wireless sensor networks, where the source can send data to a fixed number of destinations (actuators) at a different rate (multiratecast). A typi...
—Commercial backbone networks must continue to operate even when links and routers fail. Routing schemes such as OSPF, IS-IS, and MPLS reroute traffic, but they cannot guarantee...
