A Stochastic Network Calculus Approach for Performance Evaluation of Wired-cum-wireless Networks over FAN

In light of an unsatisfactory solution to QoS provision for real-time traffic on the Internet, Flowaware networking (FAN) was proposed as an alternative to existing Quality of service (QoS) architectures. Compared with IntServ and DiffServ, it provides fine-grained services and proves to be scalable. In spite of rich literatures investigating the performance issue of FAN in wired networks, little work has been done in wireless network environment, which has been gaining great popularity in recent years. In this paper, we took the first step to design a framework for the performance evaluation of Wired-cum-wireless networks over FAN (WoFAN) using Stochastic network calculus (SNC). Different from most studies which focused on the deterministic service guarantees provided by FAN, this paper shed light on the quantified stochastic analysis of its achievable level of performance. Numerical analyses are conducted to prove the effectiveness of the proposed framework.
