Abstract

ABSTRACT: Georouting are also known as Geographic routing or position-based routing is a routingprinciple that relies on geographic position information. With this information a message can be routed to the destination without knowledge of the network topology or a prior route discovery. Energy conservation and load balance are two important goals in designing routing protocols for WirelessSensor Networks (WSNs).In this paper, we focus on addressing these issues and propose an energyaware dual-path Georouting (EDGR) protocol for better route recovery from routing holes. EDGRadaptively utilizes the location information, residual energy, and the characteristics of energy consumption to make routing decisions, and dynamically exploits two node-disjoint anchor lists, passing through two sides of the routing holes, to shift routing path for load balance. The proposed EDGR is much applicable to resource-constrained WSNs with routing holes.Keywords: Energy-Aware Dual-Path Georouting, Wireless Sensor Network, Route, Energy, Topology.
