Abstract:
This thesis is written with an attempt to address some of the challenges of resource allocation in multihop wireless mesh and ad hoc networks. The main focus of this thesis is on CDMA although some of the design issues considered are applicable to TDMA networks. A framework on implementation of different network design components is suggested including power control, routing and scheduling. Also, the deployment issues of each of these network components are investigated and suggestions are made on their design to address the problems involved. These suggestions include a new distributed power control algorithm that provides end-to-end QoS guarantee, an SINR-sensitive link metric for routing, and a hybrid centralized-decentralized scheduling scheme. We also consider a relaying incentivization mechanism in the context of mesh networks for Internet access when selfish but rational users are present.
