| Abstract | Flooding technique is often used for route discovery in on-demand routing protocols in mobile ad hoc networks (MANETs) such as Dynamic Source Routing (DSR) and Ad hoc On-demand Distance Vector (AODV) routing. In this paper we present a Positional Attribute based Next-hop Determination Approach (PANDA) to improve the performance of flooding-based route discovery in MANETs using positional attributes of the nodes. These attributes may be geographical, power-aware, or based on any other quality of service (QoS) measure. We identify the “next-hop racing” phenomena due to the random rebroadcast delay (RRD) approach during the route discovery process in DSR and AODV, and show how the PANDA approach can resolve this problem. We assume that each node knows its positional attributes, and an intermediate node can learn the positional attributes of its previous-hop node via the received route-request message. Based on the attributes such as the relative distance, estimated link lifetime, transmission power consumption, residual battery capacity, an intermediate node will identify itself as good or bad candidate for the next-hop node and use different rebroadcast delay accordingly. By allowing good candidates to always go first, our approach will lead to the discovery of better end-to-end routes in terms of the desired quality of service metrics. Through simulations we evaluate the performance of PANDA using path optimality, end-to-end delay, delivery ratio, transmission power consumption, and network lifetime. Simulation results show that PANDA can: (a) improve path optimality, and end-to-end delay, (b) help find data paths with only 15%–40% energy consumption compared to the RRD approach at a moderate cost of increased routing messages, (c) balance individual node’s battery power utilization and hence prolong the entire network’s lifetime. |

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.
