WiMax or the IEEE 802.16 standard is one of the most promising broadband wireless
technologies nowadays. It is characterized by its high data rates, large coverage area,
flexible design and QoS support. The standard defines two modes of operation: Point-to-
Multi-Point (PMP) and the Mesh Mode. In the first mode, all nodes are connected
directly to the base station and communication is not allowed amongst nodes. In the mesh mode, nodes are placed in an ad hoc manner communicating to neighbors and relaying the traffic of other nodes. The goal of this thesis is to design a partitioning scheme for the frame structure of the Mesh mode. Increasing the frame utilization would
result in better support for QoS applications and optimized resource allocation, and
thus revenue increase from the service provider’s perspective.
The mesh frame is divided into control and data, which are further divided into
centralized and distributed portions. We propose a novel and efficient scheme for partitioning the data subframe between the two schedulers. We use a Markovian model
that studies the system behavior in the long run, and provides predictions based on
analysis of previous window of frames. We further enhance the decision by tuning the
partitioning through statistical analysis of smaller windows to accommodate demand
changes. Our simulations show that the proposed scheme achieves high utilization
under different network and traffic conditions and decreases the packet overflow. / Thesis (Master, Computing) -- Queen's University, 2008-10-02 18:41:36.551
