The protocol design for wireless roaming authentication is challenging because of the key management regarding users and home/visited networks. In this paper, we present two authe...
Abstract— The ability to geometrically represent sensed phenomena within a wireless sensor network can provide a more concise view than enumeration of all nodes identifying a phe...
A number of solutions have been proposed to address the free-riding problem in peer-to-peer file sharing systems. The solutions are either imperfect–they allow some users to ch...
In a sensor network the sensors, or nodes, obtain data and have to communicate these data to a central node. Because sensors are battery powered they are highly energy constrained....

Energy is a central concern in the deployment of wireless sensor networks. In this paper, we investigate the energy cost of cryptographic protocols, both from a communication and ...
