On-demand QoS-based routing protocol for ad hoc mobile wireless networks

To explore QoS issue for ad hoc mobile wireless networks is not trivial because of the high mobility of mobile nodes. Based an the DSDV (destination-sequenced distance-vector) routing protocol for maintaining up-to-date route information, previous works on QoS routing for ad hoc mobile wireless networks do require adding an extra bandwidth for exchanging QoS information. However the size and the update frequency of the routing table are increased tremendously with the number of mobile nodes. We propose an on-demand-based QoS routing protocol to achieve the QoS requirement. The goal of this paper is to discover an optimal route with minimum time delay for transmitting real-time data from a source node hop by hop to a destination node under some predefined constraints.
