How it all began: EU Project CARMENNetwork operatorsEquipment manufacturersAcademia / research institutes

Goals of CARMENEnable heterogeneous (multi-hop) wireless backhaul networks including mesh topologies for operator deploymentsMedia independence layer (code once, run everywhere)Define media abstraction layer for higher-layer servicesProvide additional information to higher layers for things like neighborhood information and radio configuration

Initial Objective

Text

Why IEEE 802.21?It offers a media independent interface (MIH_SAP) alreadyMany of the primitives defined in 802.21 for handovers can actually be reused for network management/cross-layer information exchangeIt offers the required communication mechanisms (e.g. to propagate link state updates to a central mgmt. entity)Obviously, there are still points missing to enable wireless network management and some new primitives would be needed

General Areas of InterestGetting/Setting interface capabilities (local or remote)Media independent capacity definitionMonitoringCapacity constrained HO focus on Media Independent Radio Configuration

Selected ContributionsPresentation to SGK. Grochla, W. Buga (Proximetry) Practical experiences with media-independent link controlD. Liu (China Mobile) Wireless Mesh Trial Network IntroductionS. Das (Telcordia) Use of MIH for ad hoc networksY. Ohba (Toshiba) Network management use casesI-Kang Fu, MediaTek Multi-Radio Integration for Heterogeneous Networks

Contributions to other groupsPresentation of SG to the groupsPresentation to the 802.21/802.19 joint session A. de la Oliva (UC3M), J. Lessmann (NEC), C. Niephaus (FhG) IEEE 802.19.1 as a Media Independence Service LayerPresentation of SG overview to 802.16 NetManParticipation of the SG in 802.16x CFI tutorialPresentation of SG overview to 802.11 WNG

ConclusionStudy Group was established in November 2009SG has been extended twice Considerable number of contributionsUnfortunately, the level of initiative of companies (even within 802.21 WG) is not high enough to feel comfortable with making a PARHence, this is the last SG session*
