| Abstract | Ad hoc networks, which are multi-hop and autonomous decentralized networks, have broad perspective in military communication, emergency communication, sensor networks and so on. Enhancing the performance of Ad hoc networks is one of the important objectives in the design of networks while congestion is a significant contributor that leads to network performance degradation. Many different congestion control strategies in transport layer, network layer, MAC layer and even cross-layer have been widely researched. Jian Liu et al. bring forward ATCP to improve traditional TCP congestion control in ad hoc networks [1]. Reference [2] proposes a MAC layer congestion control mechanism which mainly uses the congestion window to control the MAC's sending rate in 802.11 WLANs. D. Kliazovich and F. Granelli[3] research a crosslayer congestion control scheme, in which transport layer's data stream is adjust by the information of link layer, such as bandwidth and delay. The essential reason causing congestion is that user data rate exceeds link data transmit rate capability. Most of the congestion control strategies research how to control user data rate properly to achieve the goal. However, in this paper we investigate MAC layer intelligent split-stream scheme to improve data transmit rate capability for alleviating congestion in Ad hoc networks. In a practical Ad hoc network, due to terrain and interference, link qualities of the paths to some nodes are quite good while those to others are relatively bad. Single node conventionally selects good path expecting great performance of itself. However, multi-nodes all select good path often cause severe competition at MAC, which eventually lead to performance degradation of the whole network. |

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.
