Hybrid Scheme for Discovering and Selecting Internet Gateway in Mobile Ad Hoc Network

Abstract

Global connectivity to Mobile Ad Hoc Network (MANET) is necessary to access the

Quality of Service Routing and Mechanisms for Improving Video Streaming over Mobile Wireless Ad hoc Networks

“…Although this scheme achieves the routing overhead, it may increase route discovery delay since mobile nodes have to send a gateway discovery message every time they need a gateway. Few solutions [109] [110] propose hybrid gateway discovery schemes where the dissemination of gateway advertisements is kept limited to a small range of n-hops (proactive area). Nodes outside the coverage area use a reactive scheme to find their gateways.…”

“…Nevertheless, this metric is not always optimal in the long term. The gateway selection proposed by Iqbal and Kabir [109] is based on three parameters: the interface queue size, the total number of neighbours of each node along the route and the hop count. They define a hybrid discovery method where gateways broadcast advertisement messages when they receive a gateway discovery message from a mobile node.…”
