This paper presents a distributed grid based robust clustering protocol for mobile wireless sensor networks. An overwhelming majority of current research on sensor network routing protocols considers static networks only, while the authors consider mobile environment. Grid based robust clustering is a distributed location based, energy aware clustering protocol designed for mobile sensor networks. Grid based robust clustering utilizes node's location information during cluster head selection and introduces a new parameter called center-nest. It also has a recovery mechanism to decrease packet loss during inter-cluster communication. Simulation results show that grid based robust clustering incurs less packet loss, results in high packet delivery ratio, and exhibits robustness against moderate to high mobility of nodes.
