Optimization of Non-Uniform Sensing Coverage for Wireless Sensor Networks
The success of wireless sensor networks (WSN) depends on two factors: 1) how well the service area is monitored by the WSN's capability to sense the intended phenomenon, and 2) the way that the WSN communicates the sensed phenomenon for further analysis by the service center with acceptable time duration. The simultaneous optimization for both the sensing and communication problems is a grand challenge, especially when the service area is harsh and it can't be accessed easily by human. In this paper, we have proposed a non-uniform constructive scheme to sense and communicate the service area through a cell-by-cell, where each cell is selected randomly and the cells may have different sizes. The experimental results demonstrate the feasibility of the non-uniform constructive scheme in selecting and placing sensors to sense and communicate over the service area with minimal uncovered area and minimal overlapped sensors.
