Abstract
Title: Experimentally Modified Protocols with Transmission Count Metric for Efficient Throughput in Ad-Hoc Networks
Authors: Mr. Arun Kumar Singh, Dr. Neelam Srivastava
Abstract:
Wireless networks have many dimension devices which are connected by wireless communication links. The links are most often implemented with digital packet radios. Because each radio link has a limited communications range, many pairs of nodes cannot communicate directly, and must forward data to each other via one or more cooperating intermediate nodes. We will often use ‘time count metric’ to mean the minimum hop-count metric.
Modified protocols with the PTC (Potential transmission Count Metric) of a route is the total number of packet transmissions and retransmissions required to send a packet across the route, assuming that each link in the route retransmits the packet until it is successfully received across the link. PTC is designed for links with link-layer acknowledgments and retransmissions. The PTC metric for a route is calculated using measurements of the lossyless of each link in the route. Routing protocols select routes with the minimum PTC. PTC improves the throughput of both Dynamic Source Routing (DSR), an on-demand source routing protocol, and Destination-Sequenced Distance-Vector (DSDV) routing, a proactive table-driven distance-vector routing protocol. We present a set of design changes and implementation techniques that allow DSR and DSDV to work well with PTC.
