TLDR
An overview of the void problem is presented and the currently available void-handling techniques (as of July 2006) for geographic routing are surveyed, each designed with a different approach.Abstract:
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

Low resolution grid mapping approach for geographic routing
TL;DR: A new low-resolution grid occupancy mapping GOM approach to effectively handle local minima for existing geographic routing protocols and is well suited for scalable and dynamic mobile networks due to the reduction in probe and memory overhead and cellular structure.
Location based protocol for wireless networks
TL;DR: A location-based protocol for wireless network is proposed by using the MAC interception such that if best possible node is not possible, the data can be transferred using the second-best possible node thus introducing the intermediary nodes as well in the model.

Efficient exclusive opportunistic routing for vastly dynamic mobile Ad Hoc networks
TL;DR: An efficient Position-based Opportunistic Routing (POR) protocol is proposed which takes advantage of the stateless property of geographic routing and the broadcast nature of wireless medium to deliver data packets for highly dynamic mobile ad hoc networks in a reliable and timely manner.

TL;DR: When n identical randomly located nodes, each capable of transmitting at W bits per second and using a fixed range, form a wireless network, the throughput /spl lambda/(n) obtainable by each node for a randomly chosen destination is /spl Theta/(W//spl radic/(nlogn)) bits persecond under a noninterference protocol.
