Fault Tolerant Interference-Aware Topology Control for Ad Hoc Wireless Networks

Free registration required

Executive Summary

Interference imposes a major challenge for efficient data communication in wireless networks. Increased level of interference may increase number of collisions, energy consumption and latency due to retransmissions of the interfered data. Interference of a link is the number of nodes interfered while a pair of nodes are communicating over a bi-directional link. Approaches have been proposed to reduce interference by dropping links that create high interference. However, dropping links make a network more susceptible to node failure/departure - a frequent phenomenon in ad hoc networks. Thus dropping high interference links while keeping the network significantly connected is an important goal to achieve.
