Communications voids, where geographic greedy forwarding fails to move a packet further towards its destination, are an important issue for geographic routing in wireless networks. This article presents an overview of the void problem and surveys the currently available void-handling techniques (as of July 2006) for geographic routing. In the survey, we classify these void-handling techniques into six categories, each designed with a different approach, that is, planar-graph-based, geometric, flooding-based, costbased, heuristic, and hybrid. For each category, we present its basic principle and illustrate some classic techniques as well as the latest advances. We also provide a qualitative comparison of these techniques and discuss some possible directions of future research.read more

Cloud Based “Energy Aware” Routing Protocol for Predetection and Its Prevention of Fault Tolerance
TL;DR: DBTR as discussed by the authors is a protocol that can be used to select the next node if failure accrue, and checks fault tolerance and gives absolute solution, however, it has not found the absolute solution for detection of the problem and avoid the fault for routing protocol.
