| Abstract | Multi-constrained quality-of-service routing (QoSR) is to find a feasible path that satisfies multiple constraints simultaneously, as an NPC problem, which is also a big challenge for wireless mesh networks. There are few methods, which can solve this problem effectively so far. In this paper, we propose a novel routing scheme based on mean field network (MFN/spl I.bar/RS) to solve this problem. This algorithm first uses a function of the wireless link's delay and capacity both of which are QoS parameters as the cost function, and then seeks to find a feasible path by mean field annealing. Because MFN/spl I.bar/RS uses a set of deterministic equations to replace the stochastic process in simulated annealing (SA), and uses saddle point approximation in the calculation of the stationary probability distribution at equilibrium, thus the convergence time is much less than the algorithm based on SA. Simulation results demonstrate that MFN/spl I.bar/RS is an effective algorithm and is very fit for wireless mesh networks where the topology may be changing constantly. |

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.
