| Abstract | Consideration is given to a version of the discrete-time slotted ALOHA protocol operating with finitely many buffered terminals. The stability region is defined to be the set of vectors of arrival rates lambda =( lambda /sub 1/, . . ., lambda /sub M/) for which there exists a vector of transmission probabilities such that the system is stable. It is assumed that arrivals are independent from slot to slot and that the total number or arrivals in any slot is geometrically distributed, with the probability that such an arrival is at node i being lambda /sub i// Sigma lambda /sub k/, over all k, independent of others. With this arrival model it is proved that the closure of the stability region of the protocol is the same as the Shannon capacity region of the collision channel without feedback. The basic probabilistic observation is that the stationary distribution and certain conditional distributions derived from it have positive correlations for bounded increasing functions. Similar techniques may be of use in studying other interacting system of queues. At present it is not clear if the result depends on the choice of arrival distribution.< |

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.
