Abstract

This paper proposes two real-time control mechanisms, Distributed Real-time Control with Regulating Buffer Threshold (DRC-RBT) and Adaptive Distributed Realtime Control (ADRC), for minimizing the packet jitter. To obtain the reliable results we also construct two platforms of testbeds, wireless and wired, to evaluate the proposed mechanisms. The implemented wireless testbed has been suitably applied in the case of small networks, composed of four mobile nodes, for manageability. In contrast, by using an emulator gateway to model ad-hoc environments, the wired testbed has been applied in case of larger networks possibly with consideration of node mobility. Experimental results reveal that each of the proposed methods performs well in different situations. In static network that packet delay is not significant, DRC-RBT is a preferable method; however, this method can serve only the incoming traffic of constant bit rate nature. On the other hand, by appropriately adjusting the assigned weight value of average delay in ADRC, the obtained numerical tests suggest that ADRC can operate efficiently in both static and dynamic network scenarios.
