3. 國立中央大學資訊工程學系 3 Introduction IEEE 802.16  Wireless metropolitan area networks (WMANs)  Providing last-mile solution for residential users and small and medium-sized enterprises (SMEs)  In rural or developing countries provide a cost- effective alternative to cabled access network  Offers Wireless Internet Service Providers (WISP) a standards-based long-range, higher performance solution

4. 國立中央大學資訊工程學系 4 Introduction (cont.) Intel indicates one of the best solutions for deploying WMAN currently is:  combine Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Fidelity (Wi-Fi) network. The WiMAX proposed as a promising solution to fixed, portable and even mobile BWA (Broadband Wireless Access) system.

5. 國立中央大學資訊工程學系 5 WiMAX Network Backhaul  LoS (Line-of-sight)  10~66 GHz  5 km service range  134 Mbps Last mile  NLoS (Non-line-of-sight)  2~11 GHz  10 km service range  75 Mbps transfer data rate Internet BS SS Clients BS

8. 國立中央大學資訊工程學系 8 IEEE 802.16f-2005 IEEE 802.16f-2005 define a management information base (MIB) to IEEE Std 802.16-2004 for  MAC  PHY  Associated management procedure Provide a definition of managed objects  Enable standard-based management of IEEE 802.16 device

9. 國立中央大學資訊工程學系 9 802.16f-2005 Management Reference Model Network management system (NMS) Managed node  Collect and store the managed objects Service flow database  Contains the Service flow and the associated Quality of service (QoS) information  It have to be populated to BS and SS when a SS enters into a BS network

11. 國立中央大學資訊工程學系 11 IEEE 802.16f-2005 MIB The MIB for BS and SS is defined as two ASN.1 MIB modules: wmanIfMib and wmanDevMib. SNMP is a protocol to access the managed objects in the BS and SS. The support of SNMP is optional for the SS. The support of SNMP in this standard is compliant to SNMPv2. The SNMP agent support for SNMPv3 is optional

12. 國立中央大學資訊工程學系 12 Relationship with Interface MIB wmanIfMib is located in the MIB-II subtree. The Internet Assigned Numbers Authority (IANA) has assigned the following ifType to point-to-multipoint broadband wireless access: IANAifType ::= TEXTUAL-CONVENTION SYNTAX INTEGER { propBWAp2Mp (184) --prop broadband wireless --access point to multipoint }

13. 國立中央大學資訊工程學系 13 Relationship with Interface MIB (cont.) WirelessMAN interface table is located under transmission sub-tree: wmanIfMib::={transmission 184}-- WMAN interface table The wmanIfMib can be accessed through: iso.org.dod.internet.mgmt.mib-2.transmission.wmanIfMib (1.3.6.1.2.1.10.184)

14. 國立中央大學資訊工程學系 14 Proposed WWWNMS system Wi-Fi and WiMax Integrated Wireless Network Management System (WWWNMS) Assumptions  The system knows the mapping relationship between user and mobile device’s MAC address  The Dynamic Host Configuration Protocol (DHCP) assigns the class C IP address to the users at the same sub-domain
