Opportunistic Vehicular Routing

Free registration required

Executive Summary

In a wireless ad hoc network, an opportunistic routing strategy is a strategy where there is no predefined rule for choosing the next node to destination (as it is the case in conventional schemes such as OLSR, DSR or even Geo-Routing). Rather, an intermediate node en route acts in an impromptu fashion and takes a decision that is based solely on current circumstances. A popular example of opportunistic routing is the "Delay tolerant" forwarding to "Data mules" when a direct path to destination does not exist. Conventional routing in this case would just "Drop" the packet.
