Distributed cache updating for the dynamic source routing protocol ieee
Dynamic source routing protocol (DSR) is an on-demand protocol designed to restrict the bandwidth consumed by control packets in ad hoc wireless networks by eliminating the periodic table-update messages required in the table-driven approach.
The major difference between this and the other on-demand routing protocols is that it is beacon-less and hence does not require periodic hello packet (beacon) transmissions, which are used by a node to inform its neighbors of its presence.
Consider a source node that does not have a route to the destination.
When it has data packets to be sent to that destination, it initiates a Route Request packet.
In this paper, we propose proactively disseminating the broken link information to the nodes that have that link in their caches.
