| Abstract | The local packing (LP) algorithm, a base station distributed dynamic channel allocation (DDCA) adapting to local traffic demands, is presented. The authors show that, unlike some other DCA algorithms, even when the network has a large number of channel, it maintains a favorable performance over FCA under uniform traffic in the region of interest. More importantly, the LP algorithm has a tremendous capability of alleviating congestion at traffic hot spots. For example, with 420 channels in the network, at a blocking requirement of 1%, in comparison to only 47 Erlangs per cell that FCA could support, the LP DDCA can accommodate 100 Erlangs per cell in isolated hot spot cells and 75 Erlangs per cell in contiguous expressway hot spots. This is achieved without decreasing the load anywhere else from the normal 47 Erlangs per cell. This algorithm can be implemented, distributedly at the base stations with a simple augmented channel occupancy table, or centrally at the mobile switching center. The authors outline an easy evolutional path, for AT&T Autoplex Series II cellsites, from the current wireless network architecture to one that incorporates the new DDCA. Alternatively, one can implement it centrally without the need of a distributed database. The computation complexity of this algorithm is low and independent of the network size. |

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.
