A Novel Multicast Beneficiary in Ieee 802.16j Wimax Relay Networks

Adaptive Competitive On-Line Cost-based Routing Algorithm for IEEE 802.16j WiMAX Mobile Multihop Relay Networks

Based on the IEEE 802.16e standard, WiMAX proposes a Mobile Multihop Relay (MMR) approach defined in the IEEE 802.16j standard to extend the service area of Base Stations (BSs), and then improves the quality of received signal strength. Clearly, WiMAX MMR achieves a low-cost coverage-extension solution for the existing WiMAX network. WiMAX MMR supports three types of Relay Stations (RS): Fixed ...

Comparative performance evaluation of idle mode location management schemes for IEEE 802.16j multihop relay networks

ABSTRACT IEEE 802.16 WiMAX is a promising technology to provide broadband wireless networking access. IEEE 802.16j Mobile Multihop Relay standard introduces multihop relaying to WiMAX system. Relay stations are used to extended network coverage and enhance system throughput. To reduce power consumption, an idle mode MS does not send location update messages while moving across cell borders. Pag...

Relay Station Selection Algorithm and Scheduling Algorithm for IPTV based Services in IEEE 802.16j MMR WiMAX Networks

Increasing Reliability for IEEE 802.16j Mobile Multi-hop Relay Networks Planning

Abstract IEEE 802.16 network is a new generation of broadband networks. Recently, relay stations in IEEE 802.16j are proposed to perform as lightweight base station solutions to extend coverage and/or increase throughput. However, the 802.16j networks are tree-based structure which suffers from the single point of failure problem. In this paper, we define the coverage problem to place the base ...

Simulation of Hard Hand over (HHO) Mechanism in IEEE 802.16j Transparent Mode networks

Two different relay modes are defined in IEEE 802.16j WIMAX standard: transparent mode and non-transparent mode. IEEE 802.16j standard supports mobile station mobility; it defines three kinds of hand over mechanism: hard handover, macro diversity handover (MDHO) and fast BS switching (FBSS) In this paper we have simulated the hard hand over mechanism of IEEE 802.16j transparent mode networks us...
