Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair <stuart.kerry@philips.com> as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.11 Working Group.

June 2005 doc.: IEEE 802.11-05/0593r0 July 2005 Abstract This presentation is about the “Siemens Partial Proposal for WLAN Mesh Networking” (doc 11-05/0592r0) in response to the Call for Proposals of the IEEE 802.11s task group. We consider a mainly unmanaged WLAN mesh network. All mesh points have to authenticate in order to become part of the WLAN mesh network. Mesh points can be both access point devices and client devices. Our proposed WLAN mesh networks with wireless multi-hop communication can be deployed in different usage scenarios: residential and home networks, office networks, campus, community, and public access networks, as well as public safety networks. The proposal is centered around but is not exclusively about multi-hop path selection. A layer 2 adaptation of the AODV routing protocol is proposed. An important aspect is extensibility. Furthermore we provide contributions to security in WLAN mesh networks and to interworking. Michael Bahr, Siemens AG, Corporate Technology Michael Bahr, Siemens AG, Corporate Technology
