A new application architecture is designed for continuous, real-time, distributed wireless sensor networks. We develop a wireless sensor network for machinery condition-based maintenance (CBM) in small machinery spaces using commercially available products. We develop a hardware platform, networking architecture, and medium access communication protocol. We(More)
This paper uses a novel discrete-event controller (DEC) for the coordination of cooperating heterogeneous wireless sensor networks (WSNs) containing both unattended ground sensors (UGSs) and mobile sensor robots. The DEC sequences the most suitable tasks for each agent and assigns sensor resources according to the current perception of the environment. A(More)
This paper describes the development of a mobile sensor network test-bed at the Automation and Robotics Research Institute (University of Texas at Arlington). LabVIEW high-level programming language is used to program, control and monitor a variety of off-the-shelf hardware platforms (both sensor motes and mobile robots). The test-bed is composed of two(More)
Efficient control schemes are required for effective cooperation of robot teams in a mobile wireless sensor network. If the robots (resources) are also in charge of executing multiple simultaneous missions, then risks of deadlocks due to the presence of shared resources among different missions increase and have to be tackled. Discrete event control with(More)
This paper has two contributions. First, we present an analysis of deadlock avoidance for a generalized case of Multi Reentrant Flow Line systems (MRF) called the Free Choice Multi Reentrant Flow Line systems (FMRF). In FMRF, some tasks have multiple resource choices; hence routing decisions have to be made and current results in deadlock avoidance do not(More)

This paper presents a discrete-event controller (DEC) for the coordination of cooperating heterogeneous wireless sensors, namely unattended ground sensors and mobile robots. It describes a new method for efficient computer aided control design of a wireless sensor network. The DEC sequences the most suitable tasks for each agent according to the current(More)
Effective cooperation of robot teams in unstructured environments requires dynamic resource assignment. If the robots are also in charge of executing multiple simultaneous missions, then risks of deadlocks due to the presence of shared resources among different missions have to be tackled. This paper presents a novel approach to combine together a one(More)
U.S. Army Training and Doctrine Command (TRADOC) Pamphlet 525-66 identifies Force Operating Capabilities required for the Army to fulfill its mission for a networked Warfighter concept. Two such capabilities are Battle Command and Battle-space Awareness for which there are expectations (trust) that networked nodes will perform in a certain manner given(More)
1. Introduction Wireless sensor networks are one of the first real-world examples of pervasive computing [1, 14, 24]. Small, smart, and cheap sensing devices will eventually permeate a certain environment and, suitably coordinated, will automatically recognize the present context and accordingly readjust their behavior. Smart environments represent the next(More)
