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

Distributed in-network path planning for sensor network navigation in dynamic hazardous environments
TL;DR: This work proposes a distributed path planning algorithm for sensor network navigation in dynamic hazardous environments using geographic or virtual coordinates of sensors and based on a partial reversal method for directed acyclic graphs (DAG), which constructs a distributed in-network directed navigation graph.

A hybrid approach using mobile element and hierarchical clustering for data collection in WSNs
TL;DR: A hybrid approach, called Node Density based Clustering and Mobile Collection (NDCM), to combine the hierarchical routing and ME data collection in WSNs is presented and a new CH selection scheme based on the node density is proposed.

Opportunistic Routing with Virtual Coordinates to Handle Communication Voids in Mobile Ad hoc Networks

TL;DR: Opportunistic Routing with Virtual Coordinates (ORVC) is proposed that would improve the potential forwarding area for a packet by sending the packets to multiple locations near the destination by taking less number of hops to reach the destination.

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.
