Connectivity Improvement for Inter-Domain Routing in MANETs
Inter-domain routing for MANETs (Mobile Ad Hoc NETworks) draws increasing attention because of military and vehicular applications. Most of the proposed inter-domain routing protocols are using clustering to manage the connection between intra-domain nodes and inter-domain nodes. The distributed clustering algorithm elects within each domain gateways that connect to different domains. Also, many inter-domain routing protocols assume that all nodes are equipped with GPS devices, which is common for nodes operating in military and vehicular environments. The geographical information can be used to assist the routing protocol. In this paper, the authors propose I-GIDR (Improved Geographical Inter-Domain Routing protocol) which has several techniques to improve geo-based inter-domain routing protocol for MANETs.
