Fair resource allocation is an effective strategy to provide optimal congestion control and scheduling in ad hoc wireless networks. We present distributed flow-based access schemes for slotted-time protocols, that guarantee proportional fairness in ad hoc wireless networks in the framework of nonlinear optimization. A proportionally fair medium access control algorithm maximizes the product over all flows of an appropriate flow-based performance function.
Data networking now plays a major role in everyday life and new applications continue to appear at a blinding pace. Yet we still do not have a sound foundation for designing, evaluating and managing these networks. This book covers topics at the intersection of algorithms and networking. It builds a complete picture of the current state of research on Next Generation Networks and the challenges for the years ahead. Particular focus is given to evolving research initiatives and the architecture they propose and implications for networking. Topics: Network design and provisioning, hardware issues, layer-3 algorithms and MPLS, BGP and Inter AS routing, packet processing for routing, security and network management, load balancing, oblivious routing and stochastic algorithms, network coding for multicast, overlay routing for P2P networking and content delivery. This timely volume will be of interest to a broad readership from graduate students to researchers looking to survey recent research its open questions.

This book provides an in-depth look into recent advances in relation to novel design strategies and algorithms to improve performance and functionality of WMNs. Ten contributed chapters written by a group of well-known experts in wireless mesh networking are arranged in two parts. The first part of the book focuses on link scheduling schemes to select a subset of links for simultaneous transitions under interference constraints in an efficient and fair manner to guarantee a certain level of network connectivity. Besides, it describes channel assignment strategies to improve the network throughput in multi-radio multi-channel WMNs by means of an efficient channel utilization and minimization of the interference. The second part of the book addresses some important network planning issues related to efficient routing protocols in dynamic large-scale mesh environment, achievable capacity limit of a single wireless link between two multi-interface mesh nodes, the correctness of the mesh security architecture, fault-tolerant mesh network topology planning.
