| Abstract | A Mobile Ad hoc NETwork(MANET) is a collection of wireless mobile computers forming a temporary network without any existing wire line infrastructure. Due to the dynamic nature of network topologies and the resource constraints, routing in MANETs is a challenging task. Multipath routing can increase end-to-end throughput and provide load balancing in wired networks. However, its advantage is not obvious in mobile ad hoc networks because the traffic flows along the multiple paths may interfere with each other. In addition, without accurate knowledge of topology, finding multiple node-disjoint paths is difficult. In this paper, we propose two on-demand methods to effectively search for multiple node-disjoint paths and present the path selection criteria. Compared with Dynamic Source Routing (DSR) and the Diversity Injection method, our methods can find more node-disjoint paths and thus provide source nodes with more choices to select good quality multiple paths. We also perform simulation studies on the proposed approaches. The simulation results show that our multipath routing methods can reduce the frequency of route discoveries and balance network loads. In addition, our Heuristic Redirection multipath routing method can reduce control overheads, improve end-to-end delay, and provide fair energy consumption among mobile hosts. The purpose of this paper is to present the advantages as well as the challenges of deploying multipath routing in mobile ad hoc networks. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
