ABSTRACT
This study addresses the problem of obtaining an effective coverage of sensors in WSN for a given target area while ensuring connectivity among sensors. The problem under consideration assumes that sensors are moving in the area. We propose TLBO (Teaching Learning Based Optimization) for coverage problem with OD (Orthogonal Design) to improve the convergence rate of TLBO. Furthermore, we propose to use RNG (Relative Neighborhood Graph) to ensure the connectivity. Finally, we propose to use VF (Virtual Force) concept to achieve even more compact (i.e. effective) coverage of sensors.
