Scheduling and Call Admission Control A WiMax Mesh Networks View

Joint routing, scheduling and admission control protocol for WiMAX networks

In WiMax networks the routing and the scheduling are tightly coupled. The routing and scheduling problem for WiMAX networks is different from 802.11 based mesh networks and can be designed and operated separately. Standard problems in wireless systems include Bandwidth allocation and Connection Admission Control (CAC). In this paper we design a joint routing, scheduling and admission control pr...

Scheduling Mechanisms with Call Admission Control (CAC) and an Approach with Guaranteed Maximum Delay for Fixed WiMAX Networks

Admission Control and Flow Scheduling for IEEE

Multihop WiMAX networks show a lot of promise as the last mile in broadband connections for streaming audio and video to users. Such WiMAX networks are based on IEEE 802.16, which specifies the service classes for Q u a l i t y o f S e r v i c e ( QoS), but leaves the admission and scheduling mechanisms open. This paper presents a flow admission control and scheduling scheme for multihop WiMAX ...

WiMAX-RBDS-Sim: an OPNET simulation framework for IEEE 802.16 mesh networks

In this paper, a simulation model for IEEE 802.16 (WiMAX) wireless mesh networks with distributed scheduling is developed. It provides a framework for the evaluation of reservation-based distributed scheduling (RBDS) policies at the medium access control (MAC) layer. The simulation model, called WiMAX-RBDS-Sim, is developed under the OPNET event-driven simulation environment. It provides interf...

Ubiquitous fair bandwidth allocation for multimedia traffic on a WiMAX mesh network with multi-channels

The WiMAX, also known as IEEE 802.16, provides a mechanism for deploying high-speed wireless mesh network, (an ubiquitous wireless network) in metropolitan areas. WiMAX technology can be used as “last mile ubiquitous” broadband connections to deliver streaming audio or video to clients. Thus, Quality of Service (QoS) is very important for WiMAX networks. Providing QoS in multi-hop WiMAX network...
