Description: Service selection has a crucial effect on wireless multi-hop ad hoc network (MANET) performance. Because of the broadcast nature of wireless transmission, good service selection groups clients with nearby service providers, localizing communication, which in turn reduces inter-node interference and allows for multiple concurrent transmissions in different parts of the network. Less optimal service selection spreads traffic over the network, increasing interference and reducing overall network throughput.This thesis presents a novel cross-layer architecture for service discovery, selection and rediscovery in MANETs that closely integrates service discovery with ad hoc routing mechanisms. Extensive simulation results show that the cross-layer approach achieves network throughput five times larger than a traditional application-layer approach to service discovery. By leveraging existing routing protocol traffic, the cross-layer architecture allows clients to reevaluate their service selection, and switch to a better server to offset the effects of changes in network topology.
