Location based Spatial Position Query Processing Environment for Position Queries using Energy Aware Clustering in VANET

Abstract

Location-based spatial queries (LBSQs) refer to spatial queries whose answers rely on the location of the inquirer. Efficient processing of LBSQs is of critical importance with the ever-increasing deployment and use of mobile technologies. In a mobile environment, especially when the location of the objects change frequently and many queries are being generated, a centralized system cannot handle the query well. Hence in this work we propose a hybrid mechanism of handling the query by peer node called clusters. Nodes first listen to a broadcasting server which gets the information by beacon packets sent by the wireless nodes. In this paper, we focus on the propagation of local information originating in vehicles that is useful for other vehicles in the system. This type of activity has been described as Information Warning Functions (IWF).
