Exploiting Wireless Link Dynamics
We address the challenge of link estimation and routing over highly dynamic and bursty wireless links that rapidly shift between reliable and unreliable periods of transmission. To this end, we propose unconventional yet efficient approaches of link estimation, routing and addressing in multi-hop wireless networks to exploit wireless link dynamics instead of bypassing them for the sake of stability and reliability. The goal is to maximize routing performance parameters, such as transmission counts and throughput, by exploiting the burstiness of wireless links while, at the same time, preserving the stability and reliability of the existing mechanisms.
The contributions of this work are as follows:
Firstly, we develop relevant link estimation metrics to estimate link burstiness and identify intermediate links that can enhance the routing progress of a packet at each hop. Secondly, we propose adaptive routing
extensions that enable the inclusion of such long-range intermediate links into the routing process. Thirdly, we devise a resilient addressing scheme to assign stable locations to nodes in challenging network conditions. Our evaluation highlights the key achievements of this work when compared to the state-of-the-art: The proposed metrics identify bursty links in the network with high accuracy, the routing extensions reduce the transmission count in the network by up to 40%, and the addressing scheme achieves 3-7 times more stable addressing even under challenging network conditions.
