Android and Multi-Hop Cellular Networks
ABSTRACT
MCNs are wireless networks where cellular connectivity is augmented by client-to-client forwarding. The goal in MCNs is to provide service with as little traffic as possible on the cellular channel, in order to increase the number of users that can use the same cellular infrastructure. We propose to implement two of our previously published routing techniques that are suitable for MCNs: Cloud Routing[1] and SISR[2]. Cloud Routing enables reliable multihop forwarding in ad-hoc networks that are characterized by high client mobility and low connectivity. Instead of delivering data through a high cost flood, Cloud Routing takes a different approach in that only small set, or cloud, of data copies is forwarded toward the destination. The progress of the traffic cloud is coordinated with the help of data progress notifications exchanged over an end-to-end control channel, such as a cellular network. The advantage of Cloud Routing for cellular networks is that end-to-end data service can be provided with a much lower load on the cellular infrastructure. Therefore, instead of forwarding data, the infrastructure only needs to carry control traffic required to coordinate opportunistic forwarding.
