| Abstract | In MIMO networks, there are two transmission strategies, SM (spatial multiplexing) and IC (interference cancellation). The use of SM and IC brings additional complexity for routing and transmission scheduling of the links. Almost all existing works on throughput optimization for MIMO systems are based on the assumption that traffic routing is given and they focus only on stream scheduling, where the performance of the system is limited. In this work, we study the joint optimization problem of routing and stream scheduling for MIMO networks, where the traffic is allowed to be routed through multiple paths to take benefit from concurrent transmissions. The problem is first formulated as an Integer Linear Programming (ILP) problem, and solved optimally by using the column generation approach. An efficient online heuristic algorithm for multi-path routing and stream scheduling with dynamic traffic load is then proposed based on the column generation approach. Extensive simulation results have been conducted to demonstrate the efficiency of the proposed algorithms. |

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.
