Using cable-based mobile sensors to assist environment surveillance

There have been works done by utilizing mobile sensors as supplementary to assist the sensing coverage for the static sensor nodes in possible event happenings. Most of them assume that the mobile sensors are equipped with unlimited mobility and thus can move anywhere within the monitored field. However, the assumption of unlimited mobility has its own limitations and is unrealistic in many practical applications. Alternatively, we consider pre-deploying cables within the monitored field so that mobile sensors move along cables to destinations. In this case, we can far more relax the requirements on the mobile sensors and achieve more realistic usage despite of the complex field landforms. We find that existing cables deployed in the tunnel are perfect carriers for deploying mobile nodes which help get rid of the complex circumstance in the underground tunnel.
