Abstract: The issue of providing QoS in Ad hoc networks was studied. Aiming at existing QoS routing protocols taking no account of the local information such as node load and node collision, the QMOR (QoS-Aware multi-objective optimization routing) protocol is proposed to provide QoS in Ad hoc network, which takes QoS requirement-bandwidth as the parameter of access control, and the algorithm of route discovery/maintenance is just extension of DSR protocol. The routing selection is carried out at the destination node with multi-objective optimization algorithm of which the optimization parameters include path delay, the length of existing packets in buffer and number of retransmissions. Results of simulation showed that the QMOR protocol has better performance than DSR protocol in either static topology or dynamic topology.
