The proliferation and convergence of different types of wired, wireless and mobile networks (such as WiMAX, Wireless Mesh Networks, WPANs, WLANs, etc) and cellular-based networks are crucial for the success of nextgeneration networks. Traditional wired/wireless networks can hardly meet the requirements of future integrated-service networks which are expected to carry multimedia traffic with various quality of service (QoS) requirements. Therefore, it is necessary to develop efficient global control mechanisms that can maintain QoS requirements to maximize network resources utilization, and minimize operational costs on all the types of wireless mobile networks. In this paper, we present an overview of QoS paradigms for heterogeneous networks and focus on those based on deterministic and probabilistic QoS.

Abstract:The Third Generation (3G) cellular networks provide ubiquitous connectivity but low data rates, whereas Wireless Local Area Networks (WLANs) can offer much higher data rates but only cover smaller geographic areas. Their complementary characteristics make the integration of the two networks a promising trend for next-generation wireless networks. With combined strengths, the integrated networks will provide both wide-area coverage and high-rate data services in hotspots. There are many aspects involved in their interworking, such as mobility, security and Quality of Service (QoS) provisioning. In this paper, we present a survey of most recent interworking mechanisms proposed in the literature, and outline some important open issues to achieve seamless integration.Keywords: 3G/WLAN interworking; tight/loose coupling; mobility management; quality of services; QoS provisioning.

“…After mobility events, these identifiers may change. The QoS needs to be valid for all identifiers at all times [17]. For example, consider a user that sets up a SIP session using their globally routable identifier.…”

A-L BurnessThe proliferation of wireless local area networks has opened doors to numerous service opportunities. However, they tend to be limited to delay-tolerant applications. We envisage an environment where a single device is used for all types of communication and roaming freely between different wireless and wired technologies and network operators. To achieve this will require quality of service (QoS) handled appropriately. Within the IP community, QoS has generally been considered end-to-end over the fixed network. Wireless networks and mobile users add a new set of problems, which have only seen highly specialised solutions within the 2G/3G mobile telephone communities. This paper examines these problems and proposes a solution whereby QoS is dealt with by the end terminals through adaptive applications and end-to-end congestion control. This does not require explicit knowledge of the type of network, and does not need expensive whole network upgrades. We believe that this approach can improve the experience of users of current wireless LAN networks, and we are currently verifying and exploring our ideas on a WLAN test bed.
