The sensor nodes are typically empowered with scarce energy resource and limited computing functionality in wireless sensor networks. However, random deployment, which occur hole problem, results in reducing the data transmission performance or additional power consumption. Consequently, the coverage completeness is an important factor for the network lifetime due to the hole problem in wireless sensor networks. We proposed a hole recovery mechanism based on the grid architecture in hybrid wireless sensor networks. Moreover, virtual force theory is utilized to determine which mobile node should enforce the recovery task. By the simulation results, the proposed mechanism is demonstrated that could efficiently maintain high coverage ratio and prolong the network lifetime.
