Gateway selection in Vehicular Ad-hoc Network

Abstract

Mobile gateways are deployed to improve Internet services in Vehicular Ad-hoc Network (V aNet). In this vein, this paper argues the need for selecting an appropriate gateway for vehicles without access to the Internet according to certain criteria and based on a gateway discovery system. The proposed solution introduces a method of multiple-criteria decision analysis helping to find suitable gateways to our problem with two main design goals: i) minimizing the number of overloaded gateways ii) maximizing the number of connected vehicles. The two design goals effectively represent two conflicting objectives that we deal with finding a tradeoff in simulation results.
