We describe a novel Distributed Key Establishment (DKE) protocol in Disruption (Delay) Tolerant Location Based Social Wireless Sensor and Actor Networks (DTLBS-WSAN). In DKE, we propose that sensor nodes use neighboring signatures to establish their keys. Pre-distributed keys are used by actor nodes to strengthen communication security. We show that nodes can get guaranteed security when actors are...
Body Area Networks (BANs) are only recently beginning to revolutionize e-healthcare by making monitoring of various patients accessible and convenient for physicians and patients. Past research in BANs has focused on biosensor design, signal processing, power efficiency, and wireless protocols. However, numerous challenges plague its development and implementation to this day. One of these is the...
In this paper, we consider the problem of decontaminating synchronous networks with mobile agents using breadth-first- search (BFS) technique. We consider various networks with different number of home bases to study the relationship between the number of home bases and the mobile agents/steps required to decontaminate. Through experiments, we demonstrate that as the number of home bases increases,...
In mobile ad hoc networks (MANETs), multi-hop message relay is the common way for nodes to communicate and participate in network operations, making routing a primary issue. The early research efforts on MANET routing focused mainly on effectiveness and efficiency under the assumption of perfectly cooperative networks. However, MANETs may not be such a friendly environment for various reasons. Routing...
