Relays, Base Stations, and Meshes: Enhancing Mobile Networks With Infrastructure

Executive Summary

Networks composed of mobile nodes inherently suffer from intermittent connections and high delays. Performance can be improved by adding supporting infrastructure, including base stations, meshes, and relays, but the cost-performance trade-offs of different designs are poorly understood. To examine these trade-offs, the authors have deployed a large-scale vehicular network and three infrastructure enhancement alternatives. The results of these deployments demonstrate some of the advantages of each kind of infrastructure; however, these conclusions can be applied only to other networks of similar characteristics, including size, wireless technologies, and mobility patterns.
