Challenged networking applications such as rural internet, battlefield communication, post-disaster communication etc. cannot rely on mere DTN for its unpredictable delay and unreliable delivery probability. To meet application specific QoS constraints, in addition to DTN-enabled mobile nodes (smart phones/tablets), an ad hoc backbone infrastructure is(More)
Seamless data synchronization among peer entities is a problem for any challenged network scenarios where infrastructural supports for synchronization are not available or insufficient. Such a network follows a delay/disruption tolerant approach, in which connection or contact time among devices are intermittent and short-lived, agents may use devices of(More)
This paper gives the design and implementation of pSync, a P2P file syncing tool for challenged networks. pSync implements a number of advanced features over existing file syncing tools, such as - role based file transfer, device priority scheduling and UDP based networking; to handle intermittent and frequent connection break-ups as well as short contact(More)
