Scope
Next generation wireless networks are evolving to
accommodate a variety of services and traffic types, including data
transfer, voice, video and multimedia streaming, while allowing a
user to roam within the service area of the network, or between
networks without disrupting the quality of service (QoS) provided.
Current wireless local area networks can provide only best-effort QoS
with limited capabilities regarding mobility. Future wireless access
networks must be able to guarantee predefined levels of QoS allowing
the services mentioned above to be supported. Furthermore, the QoS
parameters should not be exceeded during intra WLAN and WLAN —
cellular handoff.
Providing QoS sufficient to support these applications over a
WLAN can be a challenging task. WLANs often allow a variable number
of users with heterogeneous QoS requirements to share a common radio
channel, usually with limited access control, making packet delivery
fluctuant and unpredictable. WLAN MAC protocols must be extended to
support prioritization and bandwidth reservation in order to enable
guaranteed QoS provisioning to users of wireless services. Also, user
mobility, as it has been manifested in extensive studies in cellular
networks, introduces a new set of QoS parameters which must be
considered when designing a local area network.
Wireless Local Area Networks cover single-hop or multi-hop
communications which can provide various network services within a
limited service area. Research and deployment of these networks has
been very rapid in the past few years, leading to the development of
a number of wireless local area network technologies, like 802.11
(Wi-Fi), 802.15.3 and HiperLAN. Even though these technologies can
provide high speed (broadband) wireless access to IP networks, they
have significant limitations, which must be overcome for allowing
seamless, scalable and stable QoS for wireless mobile users.
The goal of the special issue in IEEE Network Magazine is
to publish original research and review articles which should be
comprehensive to all readers, regardless of their specialty. This
special issue will cover comprehensively architectures, algorithms
and technologies for quality of service (QoS) and resource management
in wireless local area networks (WLANs). In particular we are
interested in tutorial, survey and original research articles on, but
not limited to the following topics:
