Scheduling in multihop WiMAX networks

Debalina Ghosh, Ashima Gupta, Prasant Mohapatra
2008 ACM SIGMOBILE Mobile Computing and Communications Review  
The links have to be scheduled in such a way so that they do not interfere with each other while maximizing the throughput of the networks.  ...  This article provides an insight to the scheduling framework presented in the IEEE 802.16 standard.  ...  Links with lower rank transmit before higherranked links. The algorithms differ in the link ranking schemes and the assignment of transmission opportunities to the links.  ...

Scheduling and CAC in IEEE 802.16 Fixed BWNs: A Comprehensive Survey and Taxonomy

Ikbal Chammakhi Msadaa, Daniel Camara, Fethi Filali
2010 IEEE Communications Surveys and Tutorials  
The main objective of this paper is to provide a better understanding of the missing components to ensure QoS support in IEEE 802.16 fixed broadband wireless networks (BWNs), namely scheduling and connection  ...  First, we highlight the key challenges in designing such schemes, for both point-to-multipoint (PMP) and mesh modes.  ...  of relay networks, the IEEE 802.16j, that is a problem very near to the mesh networks one.  ...

Time Slot Assignment Algorithms for Reducing Upstream Latency in IEEE 802.16j Networks

Shimpei Tanaka, Go Hasegawa, Yoshiaki Taniguchi, Hirotaka Nakano
unpublished
In this paper, we propose 2 kinds of time slot assignment algorithms for upstream wireless links in IEEE 802.16j multihop networks.  ...  The transmission latency is mainly affected by a scheduling delay at every relay node, which is determined by algorithms for assigning time slots to wireless links between relay nodes.  ...  Conclusion and Future Work In this paper, we proposed 2 kinds of time slot assignment algorithms for upstream wireless links in IEEE 802.16j multihop networks to reduce the upstream end-to-end transmission  ...

Handover Performance in Mobile WIMAX Networks

2016 International Journal of Science and Research (IJSR)  
ACKNOWLEDGMENTS This Master's thesis was carried out in the iCONS group of the University of South Florida.  ...  It then waits for a contention slot in an uplink frame in order to transmit its ranging request.  ...  When polling is done in multicast, the allocated slot for making bandwidth request is a shares slot, which every polled MS attempts to use.  ...

Practical Performance Measurements and Analysis of IEEE 802.16 Networks

Jarmo Siltanen, Kari Luostarinen, Timo Hämäläinen
unpublished
The WiMAX technology based on air interface standard 802.16 wireless metropolitan area network (MAN) is configured in the same way as a traditional cellular network with base stations using point to multipoint  ...  In this paper, we make practical measurements of the WiMAX-system's QoS performance behaviour of the unsolicited grant service (UGS) and real time polling (RTP) classes.  ...  ACKNOWLEDGEMENTS We express our acknowledgements to Aku Aho and Juha Kuusenmäki from JAMK University of Applied Sciences Jyväskylä, Finland for contributing the practical measurements.  ...

Performance evaluation of multicast routing protocol in WiMAX multi-hop relay environment

Chengxuan He, Université D'Ottawa / University Of Ottawa, Université D'Ottawa / University Of Ottawa
2013
To resolve the above-mentioned issues, we have created a model for our multi-hop WiMAX relay architectures.  ...  To support MBS in a WiMAX multi-hop relay network, one must consider several design issues such as the dynamic relay topology discovery in response to the mobility of the relay station, the dynamic group  ...  The scheduling algorithm allows the BS to control QoS parameters by balancing the time-slot assignments among the application needs of the SSs.Fig 1.1 shows the usage scenario that WiMAX will use in the  ...
