Boolean directional sensor orientation solution for K-coverage in wireless sensor network

摘要

In wireless sensors networks (WSNs), omnidirectional sensors often uses in k-coverage solution provided to region of interest (ROI). Some application areas seek the directional sensors due to its geographical and deployment advantages. In this paper, a systematic model has given to present the workability of directional sensors. The parameters used to describe the modelling of the directional sensors are further applied to estimate the coverage probability. Moreover, the ratio of omnidirectional to directional sensors is being estimate. Further suggestion has been made about the orientation of the sensors and simulation result has given to investigate the effect of sensor radius and offset angle value on network performance.
