We consider the problem of gathering data from a wireless multi-hop network of energy-constrained sensor nodes to a common base station. Specifically, we aim to balance the total...
In this paper, we investigate the use of limited infrastructure, in the form of wires, for improving the energy efficiency of a wireless sensor network. We call such a sensor netw...
Key management is the cornerstone for secure communication in sensor networks. Researchers have recently developed many techniques to setup pairwise keys between sensor nodes. How...
— In this paper, we consider the sensor replacement problem in hybrid wireless sensor networks composed of mobile and static sensors. Mobility equipped mobile sensors are utilize...
: This paper investigates organization problems of large wireless sensor networks. In spite of their random deployment, nodes have to organize themselves as energy efficient as pos...
