Energy efficiency is one of the most critical issues in the design of wireless sensor networks. Observing that many sensor applications for object tracking can tolerate a certain d...
Group communication has become an important component in wireless networks. In this paper, we focus on the environments in which multiple groups coexist in the system, and both in...
— While many protocols for sensor network security provide confidentiality for the content of messages, contextual information usually remains exposed. Such information can be c...
Abstract— We investigate the secure connectivity of wireless sensor networks under the pairwise key distribution scheme of Chan et al.. Unlike recent work which was carried out u...
Mobile ad hoc networks consist of mobile wireless devices which autonomously organize their infrastructure. In such a network, a central issue, ensured by routing protocols, is to ...
