Abstract | ExOR, which makes the best use of every broadcast and chooses the next hop after the transmission for that hop, is an opportunistic routing protocol in Wireless Mesh Network (WMN). While effectively increasing the throughput of the network, ExOR doesn't take any security mechanism into account. Since ExOR attempts to schedule the transmission by the cooperation of each node, the scheduling mechanism of ExOR is easily damaged by attackers. In this paper, we first introduce a variant of rushing attack, which targets on the scheduling mechanism of ExOR. The attacker violates the scheduling mechanism and forwards the fragment regardless of higher priority nodes' sending, which results in the wrong setting of other nodes' forwarding timer. And then we propose the anti-rushing mechanism, a defense against the variant of rushing attack for ExOR. This mechanism uses one-way hash chain for authentication and requires each node should send the packets with the last sender's hash that its forwarding timer setting based on to prove its timer setting is not malicious. Our mechanism is proved to be effective through a series of experiments. |

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.
