The capability of sensor nodes to collect and aggregate ambient data enables a mobile user to receive assistance from the network in charting a safe path through a potentially dangerous area. However, the information would be meaningless without localization. Applying an existing coarse-grain location-aware cluster (virtual infrastructure i.e. VI) for object detection provides only approximate location of dangerous objects as the objects are further away from the center. This distance-dependent location-based cluster creates various sizes of localized clusters, which cause inconsistency in size and thus may lead to inefficient path planning. The main contribution of this paper is to propose a fine-granularity clustering technique, that we call eVI that enhances the performance of previously-proposed VI by dividing clusters into smaller sub-clusters. Utilizing the eVI for autonomous navigation enables mobile sink to detect location of dangerous object effectively and thus result shorter safe travelled distance compared to other sector-based clusters as demonstrated in the simulation result.
