Location aided routing is an emerging approach in mobile ad-hoc networks. Location based routing propagates the packet toward the destination on the basis of location information of transmitting node and destination node. Many algorithms are devised to forward the packet in location based environment among them greedy forwarding is simplest one. In this a transmitting node forwards the packet to next node which is closer to destination than itself. Most forwarding within r and nearest within forwarding progress are the examples of greedy forwarding. With the simple and straight forward method greedy forwarding may suffers from local maxima problem where a node itself is closest to destination, therefore unable to construct the path nevertheless it exist. Many solutions were made to encounter the local maxima problem but suffers with other problem such as packet looping. In this work an efficient solution to local maxima “back tracking with exclusion” is proposed and compared with existing solutions.
