Controlled Straight Mobility and Energy-Aware Routing in Robotic Wireless Sensor Networks

Executive Summary

Power-aware routing and controlled mobility schemes are two commonly used mechanisms for improving communications in a wireless sensor network. While the former actively consider the transmission costs when selecting the next hop on the route, the latter instruct mobile relay nodes (either sensors or actuators) to pursue more promising locations so as to optimize end-to-end transmission power. Rarely, if ever, the two methodologies are exploited together for achieving relevant energy savings and prolonging network lifetime. In this paper, the authors introduce a hybrid routing-mobility model for the optimization of network communications.
