ILORIN: Identifier-locator resolution for infrastructure-less networks

In order to overcome the limitations of the current Internet addressing, it is generally accepted that the Future Internet needs a separation between identifiers and network locators. Such identifier-locator split is also needed in infrastructure-less networks, such as Mobile ad hoc Networks (MANETs) and Delay Tolerant Networks, since they are an integral part of the Future Internet. Despite the amount of work in infrastructure-based networks, only a few proposals have considered how to apply this identifier-locator split in infrastructure-less networks. The contribution of this paper is an identifier-locator resolution system that can work in sparse MANETs, which are prone to network partitions. Our approach is an identifier-locator association discovery system, which uses periodic beacons to exchange the resolution information, avoiding the establishment of shared state between nodes. Our system exploits the broadcast nature of the wireless medium, opportunistic encounters, and information replication to disseminate identifier-locator associations across the network. The results of our extensive experiments demonstrate that our solution outperforms the related work, achieving a higher identifier-locator association discovery rate.
