“…A closed-form expression for the spectral efficiency in singlecarrier frequency-division multiple access (SC-FDMA) when AMC is applied was derived in [16]. In [17], the packet drop rate, packet average delay and throughput were derived based on the Markovian queueing model when AMC is used. The blocking rate and spectrum consumption of multicast IPTV services were studied by simulations in [18].…”

Abstract-Unicast IPTV services that can support live TV, video-on-demand (VoD), video conferencing, and online gaming applications over broadband wireless cellular networks have been becoming popular in recent years. However, video streaming services significantly impact the performance of wireless cellular networks because they are bandwidth hogs. To maintain the system performance, effective admission control and resource allocation mechanisms based on an accurate mathematical analysis are required. On the other hand, the quality of a wireless link usually changes with time due to the user mobility or time-varying channel characteristics. To counteract such timevarying channels and improve the spectral efficiency, adaptive modulation and coding (AMC) scheme can be adopted in offering unicast IPTV services for mobile users. In this paper, closed-form solutions for the bandwidth usage, blocking rate, and dropping rate of unicast IPTV services over wireless cellular networks were derived based on the novel queueing model that considers both user mobility and AMC. Simulations were also conducted to validate the accuracy of analytical results. Numerical results demonstrate that the presented analytical results are accurate. Based on the accurate closed-form solutions, network providers can implement precise admission control and resource allocation for their networks to enhance the system performance.Index Terms-Adaptive modulation and coding (AMC), bandwidth usage, blocking rate, dropping rate, mobile IPTV, unicast, user mobility, wireless cellular networks.
