| Abstract | In this paper, we consider the problem of topology control by joint power control and routing to maximize the network throughput in wireless mesh networks. First, we present two mathematical formulations of the joint power control and routing problem according to two different definitions of network throughput: the total throughput and the minimal per-node throughput. To reduce the computation cost, we next decompose this joint problem into two sub-problems: the power control sub-problem and the routing sub-problem. For the first sub-problem, we design two heuristic algorithms to assign transmission powers to mesh routers, such that the total interference or the maximum node interference in the network is minimized. For the routing sub-problem, we design two linear programming formulations to maximize the total throughput or the minimal per-node throughput. Simulation results reveal the following relationship: the topology with minimum total interference has higher total throughput, while the topology with minimum maximal node interference has higher minimal per-node throughput. This can server as a guidance for network design to satisfy different throughput considerations. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
