| Abstract | Ad-hoc networks establish communication in improvised environments without requiring any fixed infrastructure. These networks are inherently prone to security attacks, with node mobility being the primary cause in allowing security breaches. Therefore secure routing is a must for such networks. A number of secure routing protocols based on trust have recently been proposed. However, all these protocols use the traditional route discovery model, where a node drops RREQ packet if its own ID is in the source route of the packet, or if it has previously processed the packet. A misbehaving node takes advantage of this vulnerability and forwards the RREQ fast, so that the RREQ received from other nodes are dropped and the path discovered includes itself (the misbehaving node). In this paper, we present a unique trust based method which is not vulnerable to this behavior. In our method, each node broadcasts a RREQ packet if it is received from different neighbors. A secure and efficient route to the destination is calculated as a weighted average of the trust value of the nodes in the route, with respect to its behavior observed by its neighboring nodes and the number of nodes in the route. We evaluate the misbehaving node detection rate and the efficiency of our method along a number of parameters. Results show that our method increases the throughput of the network while discovering a secure route. |

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.
