Analysis of a traffic flow optimization protocol for hybrid MANETs

The communication between wireless ad-hoc networks and infrastructure-based networks is essential to extend Internet beyond its traditional scope, to remote inaccessible areas, making Web services in ad-hoc networks available anytime, anywhere. The mobile nodes in a wireless ad-hoc network must be able to detect available gateways and select one of them if they want to have Internet access. In this paper, the analyzed protocol proposes the transfer of the mobile gateway functionality to another node present in the covered area of the access point acting as a router. There were evaluated the following performances of the proposed protocol (using OPNET): packet delivery ratio, overhead and the packet delay.
