We consider the problem of routing and centralized scheduling for IEEE 802.16 mesh networks. We first fix the routing, which reduces the network to a tree. We then present scheduling algorithms which provide per flow QoS (Quality of Service) guarantees to real and interactive data applications

Conventional resource management systems use a system model to describe resources and a centralized scheduler to control their allocation. We argue that this paradigm does not adapt well to distributed systems, particularly those built to support high-throughput computing. Obstacles include

transmission between cells for the downlink. Here, data are transmitted simultaneously either coherently or non-coherently from multiple cells to a single mobile station. In this paper, a centralized MAC scheduling approach for joint transmission coordinated multi-point (JT CoMP) is proposed. Since several

Abstract — The IEEE 802.16 mesh mode supports two scheduling mechanisms, namely centralized scheduling and distributed scheduling. Centralized scheduling is based on a routing tree to offer centralized control. As we will show, the structure of the routing tree has a significant impact

IEEE 802.16 mesh standard specifies uses Time Division Multiple Access (TDMA) technology to provide end-to-end Quality-of-Service (QoS). However, the performance in the mesh depends on TDMA scheduling algorithms. A new class of TDMA scheduling algorithms, based on the Bellman-Ford algorithm

IEEE 802.16 protocol [1,2] specifies two different modes of operation. The first mode of operation is the point-to-multipoint (PMP) mode. In the PMP mode, each 802.16 access point has a dedicated broadband connection to the Internet. Wireless terminals connect to the access points on their first hop and their traffic goes to the

Abstract — IEEE 802.16 standards for Wireless Metropolitan Area Networks (WMANs) include a mesh mode of operation for improving the coverage and throughput of the network. In this paper, we consider the problem of routing and centralized scheduling for such networks. We first fix the routing, which

In an on-demand video server environment, clients make requests for movies to a centralized video server. Due to the stringent response time requirements, continuous delivery of a video stream to the client has to be guaranteed by reserving sufficient resources required to deliver a stream. Hence

central entity in the infrastructure mode of an 802.11 wireless network, we propose a new centralized scheduling-based MAC protocol which is based on the popular DCF mechanism. This simple yet efficient scheme illustrates a new paradigm for realistic medium access control protocol design for next

the signaling cost of centralized scheduling in IEEE 802.16 mesh mode. A simple analytical model for signaling cost is proposed. Simulation results has demonstrated the correctness of the model. Keywords-802.16; WiMax; Mesh; signal; I.
