IEEE 802.16e standard specifies a system for combined fixed and mobile broadband wireless access. The voice-over-Internet protocol (VoIP) is an important application in IEEE 802.16e system. The algorithm proposed allocates the extra-bandwidth according to the flow's priority, the lagging flow is compensated according to the service it has lost, and the leading flow relinquish bandwidth proportional...
The voice-over-Internet protocol (VoIP) has attracted a great deal of attention in the field of wireless mobile networks. In this paper, we propose an improved ertPS scheduling algorithm for VoIP services in IEEE Std 802.16e system. It can solve both the problems waste of uplink resources caused by the UGS algorithm as well as MAC overhead and access delay caused by the rtPS algorithm, it also identify...
