Routing and Quality of Service in Mobile AdHoc Networks with TORA/INORA

We propose INORA, a network layer QoS support mechanism in adhoc networks, which makesuse of the INSIGNIA in-band signaling mechanism and TORA. We present aneffective couplingbetween TORA and INSIGNIA to get routes that are “best-able” to provide QoS requirementsfor a flow. INORA also provides congestion control. We present two schemes called”Coarse feedback scheme” and “Fine feedback scheme” under the INORA frame work. Weshow that under heavily loaded conditions, the INORA schemes perform better than whenthe signaling protocol and the routing protocol operate without feedback.
