Abstract
Multimedia Information delivery in public transportation systems is gaining increasing prominence. This paper proposes mesh-tree architecture for low latency and highthroughput data transfer to mobile vehicles along approach roads in and around a bus station. Prior works have demonstrated 802.11b-based wireless chain topology for mobile vehicle connectivity along railroads. However, the chain topology is known to result in high hop counts and poor end-to-end latency. Furthermore, a break in any of the links would disconnect the remainder of the chain from the network. Hence, we propose meshtree architecture in order to overcome these drawbacks of the conventional chain topology. We discuss the architecture, antenna selection, deployment and performance results of a 14-node multihop 802.11a/g-based wireless test bed1 that mimics a large bus terminus. Our results clearly underscore the potential utility of mesh-tree architecture in achieving low latency and highthroughput data transfer leading to superior mobile vehicle connectivity.
