Geographic Routing with Logical Levels Forwarding for Wireless Sensor Network
Location information is essential in many applications of WSNs, it is natural to use this information for routing as well. Location-based protocols or geographical routing protocols to exploit the location information of each node to provide efficient and scalable routing. Various routing algorithms that feat geographic information (e.g., GPSR) has been aimed to attain this goal. These algorithms refer to all nodes by their location, not address, and use those coordinates to route greedily, when possible, towards the destination. However, there are dozen's situations where location information is not available at the node. This paper presents a new geographical routing protocol for Wireless Sensor Networks (WSN) energy-efficient data forwarding, called GRPW (Geographic Routing Protocol Washbasin).
