Technologies used in Physical MAC-CPS and MAC-Security Layers of IEEE 802.16j Mobile Multi-Hop Relay (MMR) Networks
Authors: ,
Abstract: The IEEE 802.16 standard was formed in 1998 and approved in Dec-2001, to develop air interface standard for wireless broadband. The relay task group of IEEE 802.16 standard extended the IEEE 802.16e-standard with a new standard called IEEE 802.16j mobile multi-hop relay (MMR) standard. The IEEE 802.16j standard supports multi-hop relay operation was a relay station relay packets between base station and subscriber station. This article provides insight and understanding of the IEEE 802.16j mobile multi-hop relay (MMR) networks and describes some of the technologies used in physical, MAC-CPS and MAC-security layers of IEEE 802.16j wireless communication. The current Technologies of Physical and MAC layers are SOFDMA, Mobile IEEE 802.16j MMR channel encoding process, Relay station grouping and Messages, Ideal mode operation, Paging and Location management, Privacy Key Management protocol, IEEE 802.16j MMR physical layer security, comparison of WIMAX OFDM, OFDMA and SOFDMA, Up-link Sub Frame: down link Sub Frame, IEEE 802.16 Protocol Stack, Privacy and Key Management Protocol and authorization. We have described completely about all the above technologies in this article.
