A problem of decentralized self-deployment for mobile sensor networks: Barrier coverage between landmarks

Coverage is an important issue in a sensor network. In this paper, we consider a problem of barrier coverage between two landmarks using a network of self-deployed mobile sensors. We propose a decentralized motion coordination algorithm for the mobile sensors so that they form a sensor barrier between two given landmarks autonomously. The algorithm is theoretically developed using some simple rules that were inspired from the animal aggregations observed in nature. The effectiveness of the proposed algorithm is demonstrated via numerical simulations.
