A QUALITY OF SERVICE BASED AODV WITH QoS-AWARE ROUTING ALGORITHMS FOR MANETs
... congestion. Using Ad-hoc on-demand QoS routing (Chen and Heinzelman, 2005) it provides an end-to-end QoS with delay and bandwidth constraints. Due to mobility in unsynchronized wireless environment, there is a chance of link broken. A stable QoS routing protocol is proposed (Shahram, Bita and Ali Mo ...
