AMGRP: AHP-based Multimetric Geographical Routing Protocol for Urban environment of VANETs

Abstract

The work presented in this paper proposes an efficient routing protocol named AHP-based Multimetric Geographical Routing Protocol (AMGRP) as it adopts an Analytical Hierarchical Process (AHP) while considering multiple routing criteria such as mobility metric, link lifetime, node density and node status which have been accepted as crucial factors for better performance of a protocol. The protocol implements the computed single-weighing function to identify a next hop node within a defined range which can ensure an enhanced forwarding process. The simulation results in the paper have proved that the designed protocol performs better when compared with GPSR and SLD-GEDIR protocols in an obstacle modelled urban vehicular environment.
