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 costeffective alternative to cabled access network
 Offers Wireless Internet Service Providers (WISP) a
standards-based long-range, higher performance
solution

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.

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

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

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

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
}

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)

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
