A QoS-based Routing Algorithm in Ad Hoc Network

With the development of Ad Hoc Network, the demand of the users becomes more and more than ever before, some business requires the ability not only to communicate, but also to guarantee delay and bandwidth. This paper puts forward a QoS-based multipath routing protocol QMPSR. It takes bandwidth and delay constraint into account, it can find several paths to provide QoS guarantee. Simulation shows that QMPSR protocol is better than QoS-MSR. Its packet delivery ratio is higher, average delay is less, even the increased routing overhead caused is not too much.
