An architecture to enable delay tolerant content-centric and host-centric communications in MANETs comprised of smart phones is disclosed. This architecture allows cross network communications and Internet sharing, assuming that at least one of the smart phones has internet connectivity. The architecture includes a routing mechanism for content-centric communications, as well as routing algorithms for host-centric communications. In one embodiment, a combination of OLSR and a modified variant of PRoPHET is used to create preferred routing paths for content-centric communication. In another embodiment, variations of store and forward, such as binary spray and wait, are used for host-centric communications. These communications between mobile devices utilize wireless communications, such as IEEE802.11.

Architecture for content and host-centric information dissemination in delay-tolerant MANETs

In one aspect, a technique is provided for protecting a data set with a parity set defined by a bipartite graph having a degree distribution that includes no parity symbol having a degree less than three. In another aspect, a parity set defined by an irregular bipartite graph is transmitted along with the data set, and corruptions in the data set are decoded using the data set and the parity set. In another aspect, a particularly useful degree distribution for the parity symbols is defined.
