A service-aware dynamic bandwidth allocation with CoMP is proposed in the heterogeneous 5G fronthaul network. Simulation results show that the throughput and delay performance of users have been improved, and the QoS for high priority users can be guaranteed preferentially.
Long Term Evolution (LTE) holds the promise to enhance the capacity and speed of mobile communication by supporting Multimedia Broadcast/Multicast Services (MBMS) over a single frequency network (MBSFN), where numerous cells transmit an identical waveform that is synchronized in time for a specific time interval. For improving the performance of SFN, ultra-extended cyclic prefix duration has been...
In this paper, we propose an adaptive bandwidth allocation (BA) and connection admission control (CAC) mechanism based on game theory for polling services in IEEE 802.16 broadband wireless networks. A noncooperative two-person general-sum game is formulated where the base station and a new connection are the players of this game. The game formulation provides not only the decision on accepting or...
In next generation wireless networks like WiMAX, a dynamic Call Admission Control (CAC) plays an important role to ensure Quality of Service (QoS) of existing users and to efficiently utilize network resources. We propose a predictive CAC namely Wireless Fair Intelligent Admission Control (WFIAC) that admits or rejects a new incoming connection base on resource availability and load in the network...
In WiMAX architecture to avoid congestion at the base station, a mechanism namely WiMAX Fair Intelligent Congestion Control (WFICC) was proposed in [11]. WFICC ensures that the traffic is scheduled in such a way that the base station output buffer operates around a target operating point, without violating the Quality of Service (QoS) requirements of connections. However, only preliminary results...
