| Abstract | Since the energy constraint is a fundamental issue for wireless sensor networks, the expectation of network lifetimes becomes a critical performance index. In actual applications, the data traffic on an available routing path could fluctuate from time to time, so there is a compelling need for a robust routing strategy to make the links robust enough when the link outage happens. In the paper, we jointly integrate the maximization of network lifetime and the designing of robust routing strategy into consideration, by which both two subproblems are modeled in a framework of cross-layer nonlinear optimization. By using the popular anti-risk methods popularly used in financial mathematics, our proposed cross-layer optimization problem can be transformed to a convex expression, while its uncertain probabilistic constraints are further changed to a specific solvable expression. Inspired by the particle swarm intelligence in recent development of evolutionary computation, a penalty function based method is introduced and applied in the optimal solution searching process. The effectiveness of our robust routing design is validated by the extensive simulation results, and the quantitative interactions among different neighboring links are also analysed in a typical network topology. |

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.
