Abstract: Lately, Greedy Forwarding Strategy (GFS) is express as a basic mechanistic in geographic routing for Mobile Ad Hoc Networks (MANETs). GFS employs the shortest path between two connected nodes. The research’s analysis of networks that using GFS indicates that some areas of the MANET are more decumbent to high traffic load compared with other places. This situation is called hot spot phenomenon. Accordingly, these hot spot nodes become constrained in terms of many issues and seem to be died fast. The performance of GFS becomes limited to these hot spot nodes. The whole MANET fails, as GFS fails to function well in this area. This paper takes an in depth look at the reason behind greedy failure. Lastly, the work concludes the most appropriate characteristics that should be consider for enhancing greedy scheme to be compatible with the unique features of MANET.
