Abstract-The efficiency of sensor networks depends on the coverage of the monitoring area. Although in general a sufficient nuniber of sensors are used to ensure a certain degree of redundancy in coverage so that Sensors can rotate between active and sleep modes, a good sensor deploynient is stilI necessary to balance the workload of sensors. In a sensor network with locomotion facilitieg sensors can mow-e around to self-deploy+ The movement-assisted Sensor deployment deals with moving sensors from an initial unbalanced state to a balanced state. Therefore, various optimization problems can he defined to minimize diflerent parameters, including total moving distance, total numher of moves, communicstiodcomputation cost, and convergence rate. In this paper, we propose a Scan-based Movement-Assisted sensoR deploymenT method (SMART) that uses scan and dimension exchange to achieve a balanced state. SMART also addresses a unique problem called communication holes in sensor networks. Using the concept of load balancing, SMART achieves good performance especially when applied to uneven distribution sensor networks, and can be a complement to the existing sensor deployment methods. Extensive simulation has been done to verify the effectiveness of the proposed scheme.
In REF , a scan-based movement-assisted sensor deployment method that uses scan and dimension exchange to achieve a balanced state is proposed.
