| Abstract | Geographic random forwarding (GeRaF) is a location based distributed routing protocol that allows wireless networks with aggressive sleep cycles of its nodes to deliver messages with low latency. Hybrid-Automatic Repeat Request (H-ARQ) based intra-cluster geographically informed relaying (HARBINGER) is a protocol based on GeRaF with link-layer based adaptive error control techniques and promises better performance than GeRaF. In this paper we will study the performance of HARBINGER relative to GeRaF. We study the energies required for a message to reach its destination with a given latency bound, for both GeRaF and HARBINGER, with a practical High Speed Data Packet Access (HSDPA) based system. In particular, we highlight the different circumstances under which each protocol delivers a better energy efficiency. We propose simple modifications to the GeRaF protocol with which it can achieve the same or better performance as HARBINGER at lower node densities with lesser implementation complexity. |

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.
