| Abstract | Mobile elements (MEs) have been used to improve the scalability and the performance of wireless sensor networks (WSNs). In most of these approaches, the ME traverses an area of interest with a pre- determined path set by the basestation (BS) and is trusted to follow the determined path. This assumption is not realistic since the ME carries essential information about the network making it appealing to various attackers. An ME can be captured and can be used to deceive the BS. As a result, further protocols are required to verify the path travelled by the ME. In this paper, we propose two protocols to control the path of a semi-trusted ME using cryptographic methods including Message Authentication Code (MAC), and hash chains. First protocol collects node encounter information with MACs and allows the BS to construct an approximate path using this information. Density of the nodes and the broadcast range play an important role in the quality of the constructed path. Second protocol enforces a strict path using hash chains. The ME helps the sensors verify a hash chain in a distributed manner and deviation from the path results in breaking the chain. We believe these protocols will serve as a first step to a model where the ME has to prove all of its actions to the BS. |

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.
