Secure mobile wireless ad-hoc networks are frequently described in the technical literature as highly-desired and feasible. However only few stable and scalable physical realizations of such MANETs were actually reported. In this paper, we describe SWAT (a secure wireless agent-based testbed), a physical network of handheld and stationary computing nodes(More)
—In this paper, we consider the problem of placing , with course-grained control, a large number of wireless networked sensor nodes employing a clustering network architecture. The goal of the deployment strategy is to maximize the lifetime while ensuring connectivity between cluster-heads so that samples from the monitored area may be forwarded to a fusion(More)
—This work proposes a framework for jamming wireless networks that incorporates probabilistic models of internal states and observable characteristics of link protocols, where protocols are divided into two general classes: random access (RA) or channelized access (CA). Without exact knowledge of network parameters and internal state, the proposed(More)
The distribution of data in large dynamic wireless sensor networks presents a difficult problem due to node mobility , link failures, and traffic congestion. In this paper, we propose a framework for adaptive flooding protocols suitable for disseminating data in large-scale dynamic networks without a central controlling entity. The framework consists of(More)
We will demonstrate the Secure Wireless Agent Testbed (SWAT), a unique facility developed at Drexel University to study integration, networking and information assurance for next-generation wireless mobile agent systems. SWAT is an implemented system that fully integrates: (1) mobile agents, (2) wireless ad hoc multi-hop networks, and (3) security. The(More)
