| Abstract | The paper presents two failure detection mechanisms, implemented at the MAC layer for nodes used in wireless sensor networks, in order to cope with transient or permanent node failures. Specifically, the failure detection mechanisms are particularly suited for periodic workload applications and MAC protocols that employ four-way handshaking (RTS/CTS/nDATA/nACK) for collision avoidance. One failure detection mechanism is reminiscent of the Hello protocol that is sometimes implemented at the Network layer, and uses a fixed time threshold, while the other mechanism uses the RTS packets count as a metric for determining that a failure has occurred. The paper focuses on the impact of implementing a failure detection mechanism on the performance of the network, in addition to comparing the two failure mechanisms. Moreover, the effect of buffer lengths variations is investigated on the setting of the fault tolerance parameters and on the network performance. |

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.
