Secure and energy efficient transmission is a main concern in many wireless sensor network applications. In this paper, two types of denial-of-service attacks that affect the rout...
Monitoring human movements using wireless sensory devices promises to revolutionize the delivery of healthcare services. In spite of their potentials for many application domains,...
In contention-based sensor networks, nodes compete to access a shared channel for data transmission and collision is a common challenge. For power conservation, periodical active/s...
This paper investigates a class of mobile wireless sensor networks that are unconnected most of the times; we refer to them as delay–tolerant wireless sensor networks (DTWSN). T...
In energy constrained wireless sensor networks, energy conservation techniques are to be applied in order to maximize the system lifetime. We tackle the problem of increasing netw...
