GOAFR: An Optimal Algorithm for Geographic Routing in Wireless Sensor Networks
Geographic Routing is the most widely used technique for Scalable Wireless Routing. It can be considered as a lean version of source routing appropriate for dynamic networks. In this paper, the authors propose an algorithm based on Greedy routing and face routing Techniques. GOAFR Algorithm is used in both average case and Worst case environments. This Algorithm provides good enough result for routing and it outperforms other routing algorithm such as AFR. GOAFR does guarantees the source to destination delivery of data. More over they improve this Algorithm using early fall Back Technique so that they can reduce the delay in Routing.
