Inter-domain routing for MANETs (Mobile Ad Hoc Networks)
draws increasing attention because of military and vehicular
applications. The existing Border Gateway Protocol (BGP) is the de
facto inter-domain routing protocol for the Internet. But BGP is not
applicable to MANETs because the BGP design is based on a static
Internet which does not support dynamic discovery of members, and
cannot scale to mobile, dynamic topology environments.
The proposed geo-based inter-domain routing (GIDR) protocol
obtains efficient communications among MANETs and achieves
scalability in large networks by using geo-routing packet forwarding
scheme and clustering technique. The basic structure of GIDR is
clusters in each domain. The distributed clustering algorithm elects
within each domain a Cluster Head (CH). The cluster head in the
subnet acts as local DNS for own cluster and also (redundantly) for
neighbor clusters. The cluster head advertises to neighbors and the
rest of the network its connectivity, members, and domain
information. The advertising protocol plays the role of BG Protocol.
Geo-routing is the main packet forwarding scheme in GIDR.
Assuming that all nodes are equipped with GPS, greedy forwarding
is a straightforward routing scheme and can be easily standardized
and implemented in all “coalition” nodes. Moreover, it is inherently
scalable and is “address” independent (thus, it works across domain
boundaries). If greedy forwarding fails, the packet is “directionally”
forwarded to the “most promising” node along the advertised
direction, i.e., direction forwarding. The experiments have shown
that the proposed inter-domain routing has achieved scalability and
robustness to mobility. The simulation results with Airborne
Backbone Network, an important application domain in Military, as
one of the domains are also presented in the paper.
