Link Scheduling With Hard QoS Guarantee In Wireless Mesh Networks Amir reza Taheri Amirreza Taheri@gmail com Date of Submission 2013 05 19 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan Iran Degree M Sc Language Persian Supervisors Hossein Saidi hsaidi@cc iut ac ir Naghmeh Sadat Moayedian moayedian@cc iut ac ir Abstract Wireless mesh network WMN is promising technology for next generation networks because it can provide extended coverage range power consumption reduction and increased throughput simultaneously Multi hop concept of this networks leads to less path loss and shadowing effect and so coverage range can be extended Also these networks need little cabling engineering and this make their setup cheaper But one of these has less QoS delay and jitter more users equals to more collisions which is equivalent to throughput degradation Coverage range extension leads to less QoS and throughput because it needs more hops According these facts acceptable performance of a WMN is equivalent to solving an optimization problem which takes into account mentioned factors concurrently This is hot topic research as a NP hard problem in WMNs nowadays Scheduling plays an important role in providing QoS support to multimedia communications in WMNs In this thesis a novel algorithm based on Genetic algorithm with Spatial Reuse for improving centralized scheduling and optimal time slot allocation in Wireless Mesh Networks is presented The proposed algorithm considers hard QoS spatial reuse for efficient use complete interference model and the impact of node positions in topology Simulation results show that the proposed scheduling algorithms with hard QoS quarantine condition can provide QoS support in terms of end to end delay and throughput for different traffic type Keywords WMN Link scheduling QoS NP Hard PDF created with pdfFactory trial version www pdffactory com
