| Abstract | Many wireless sensor network (WSN) applications require real-time communication. One of the most important and challenging issues in real-time applications of resource-constrained WSNs is providing end-to-end delay requirement. To address such an issue a few QoS routing protocols have been proposed. Also, in many applications, the delay level required by the data packets is different. In this paper, we focus on building an energy-efficient real-time routing protocol called EERT which routes the differentiated classified packets towards the destination node via a modular approach. It takes into account both power transmission costs and residual energy of routers along with nearness of node to the shortest path and link usage in the energy-efficient module in order to prolong the network life time. Moreover, EERT employs a new policy called re-routing policy which allows the packets of a specific class to be routed as the packets of a lower/higher real-time class in particular situations. In this way, it can improve real-time performance by means of reducing the packet dropping in routing decisions. |

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.
