Abstract | In energy constrained wireless sensor networks, it essentially requires to make full use of the energy and maximize the network lifetime even when facing some unexpected situations. We consider an emergent situation that a mobile cluster head is broken down, which leads to the missing packets. We aim at recovering the failure cluster and achieving balanced energy consumption to prolong the network lifetime. An efficient approach is proposed for recovering the failure cluster by selecting multiple static sensor nodes as the cluster heads to collect packets and transmit them to the sink node. Simulated Annealing algorithm is utilized to achieve the uniform deployment of the cluster heads. The new cluster heads are dynamically changed in order to keep energy consumption balanced based on our energy consumption model. Among the new cluster heads, packets are transmitted through multi-hop forwarding path found by Dijkstra's algorithm, which is dynamically updated according to the energy cost of the path and current energy of the node. The experimental results show that lifetime is prolonged and the failure cluster is recovered. |

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.
