| Abstract | In a multihop wireless network, the throughput performance decreases seriously because of inter-flow and intra-flow collision. The backoff algorithm is the de facto function to resolve collision in 802.11 networks. In this paper we study the impact of five back-off algorithms on the performance of 802.11-based multihop wireless networks with different network topology and flow patterns. Simulations show that the backoff algorithms have big influence on the performance of both UDP and TCP flows. But none of the current backoff algorithms can improve the throughput and fairness performance in multihop wireless networks efficiently. It shows that the traditional random backoff algorithms are no longer suitable for collision resolution in distributed multihop wireless 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.
