Abstract

In Wireless Sensor Networks, sensor node's energy consumption can be balanced by the mobile sink. Due to the sensor node's limited energy, storage capacity, computing power and random mobility of sinks, it is a challenging task to find the route for data dissemination in the wireless sensor networks. Sensor nodes need to reconstruct their routes for efficient data delivery to the mobile sink latest location. In this paper, we propose a Virtual Grid-based Backbone Structure Type scheme (VGBST) to maintain optimal routes to mobile sink latest location and to minimize sensor nodes routes reconstruction cost.
