An Adaptive Delay-Minimized Route Design for Wireless Sensor-Actuator Networks

Wireless Sensor-Actuator Networks (WSANs) have recently been suggested as an enhancement to the conventional sensor networks. The powerful and mobile actuators can patrol along different routes and communicate with the static sensor nodes. This paper is motivated by applications in which the objective is to minimize the data collection time in a stochastic and dynamically changing sensing environment. This is a departure from the previous static and deterministic mobile element scheduling problems. In this paper, the authors propose PROUD, a probabilistic route design algorithm for wireless sensor-actuator networks.
