| Abstract | The IEEE 802.15.4 specification does not include RTS/CTS mechanism to avoid the hidden/exposed node problem, for the consideration of constructing the low energy consumption networks. However, based on the modified CSMA/CA algorithm in LR-WPANs, the hidden node collisions will repeat up to aMaxframeRetries (default value is 3) times until the collided packets are discarded with a high probability. Therefore, a fast recovery mechanism is proposed in this paper to achieve the fast self-healing with negligible control overheads when the networks suffer the hidden node collisions. When the coordinator recognizes the hidden node collision occurs, it will issue a group polling ACK (PACK) to indicate the priority of the collided packets retransmission. Simulation results demonstrate that the proposed PACK mechanism is able to improve the network throughput and avoid the continuous hidden node collisions efficiently. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
