Abstract Wireless Sensor and Actor Networks (WSANs) engage mobile nodes with actuators to respond to certain events in inhospitable environments. The harsh surroundings make actors susceptible to failure. Tolerating occasional actor failure is very important to avoid degrading the performance. In some cases, multiple actors simultaneously fail which makes the recovery very challenging. In this paper, we propose a new recovery approach which can handle simultaneous failures in WSANs. The approach is based on ranking network nodes relevant to a pre-assigned root actor. Ranking creates a tree to be used for coordinating the recovery among nodes. To minimize the recovery overhead, the nodes are virtually grouped to clusters and each node is assigned a recovery weight as well as a nearby cluster member which serves as a gateway to lost nodes. Designation of cluster heads is based on the number of children in the recovery tree. The simulation results confirm the correctness and effectiveness of the proposed approach in restoring network connectivity and also show that on the average the incurred overhead is low compared to contemporary single-failure recovery approaches.

About National Digital Library of India (NDLI)
NDLI logo

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.
