Abstract

With the advancement in technology, many users carry wireless computing de-vices e.g., PDAs, cell-phones etc. Such devices can form mobile ad hoc networks and communicate with one another via the help of intermediate nodes. Such ad hoc networks are very useful in several scenarios e.g., battlefield operations, vehicular ad hoc networks and disaster response scenarios. The ability to access important information in these scenarios is highly critical. Many ad hoc routing schemes have been designed for ad hoc networks but such routing schemes are not useful in some challenging network scenarios where the nodes have intermittent connectivity and suffer frequent partitioning. Recently, disruption tolerant network technologies [5, 12] have been proposed to allow nodes in such extreme network-ing environment to communicate with one another. Several DTN routing schemes [4, 14] have been proposed.
