GUIDE-Gradient: A Guiding Algorithm for Mobile Nodes in WLAN and Ad-Hoc Networks

Free registration required

Executive Summary

Whereas there is a lot of work related to finding the location of users in WLAN and ad-hoc networks, guiding users in these networks remains mostly an unexplored area of research. In this paper, the authors present the concept of node-to-node guidance and introduce a method that can be used to implement it. This method relies on the computation of a local gradient in the neighborhood of the moving node. They named this protocol GUIDE-gradient, which is a GPS-free and infrastructure-free node-to-node guiding system. In this paper, they also discuss how the guiding algorithm can be generalized to node-to-node guidance in multi-hop ad-hoc networks.
