    Nowadays, services targeting home and business users, such as Internet access, digital television or online entertainment are taken for granted. However, our lifestyle creates the need for extending the reach of such services but also the need for new ones, targeted to people on the move. With complex wireless networks forming around us and a new range of services becoming available, an enhanced service management paradigm is required. This work introduces a novel framework for the management of services in wireless environments, considering the diverse requirements and conditions. Using a wireless media service as a case study, simulation results indicate that our policy-based approach offers a flexible framework where both business and user expectations are met. User preferences guide service customization while statistical processing of user requests directs service adaptation. View full abstract»

  • Policy-based model-driven creation of adaptive services in wireless environments

    This article advocates the shift of the adaptive service engineering attention from the external service execution environment to the internal service logic itself. This article presents a novel adaptive service creation solution called POETRY that takes advantages of two promising techniques: PBM (Policy-based Management) and MDA (Model-driven Architecture). In particular, the POETRY service creation framework has investigated the thought of utilizing a policy-based management method to describe and control the internal logic of adaptive services and the method of utilizing MDA models to describe the adaptive service information model. The design details and operations of POETRY are presented and showcased via a typical adaptive service scenario. View full abstract»

  • Policies for the management of services in CDMA-based segments of the b3g world

    'The unstoppable desire and need for ubiquitous wireless access and high quality provision of pioneer multimedia brought about a remarkable proliferation of wireless networks and services, reflected in the BeyondSG (B3G) world. In such a versatile environment, legacy management functionalities are hindered by high spatial and temporal context variations. The idea of policy based management that governs the behavior of managed elements by using policy rules, promises to reduce complexity and operating costs while at the same time satisfy service level agreements and offer wise resource usage In this paper we focus on 3G CDMA-based systems, which are expected to be indispensable part of wireless B3G infrastructures, and ire first define and format policies for the allocation of demand (users per serine, location) to available carrier frequencies Then, an evaluation process to access those policies according to certain objectives is proposed. Validation through indicative simulated scenarios shows that the proposed evaluation process can be used to derive robust policy rules to tackle with the demand fluctuations, service diversities and power/interference constraints in a heterogeneous B3G environment.

  • Policy-based channel access mechanism selection for QoS provision in IEEE 802.11e

    The appearance of the 802.11e standard made the 802.11 wireless local area networks (WLANs) capable of providing different levels of quality of service (QoS). This standard defines two new channel access mechanisms (CAMs), namely the enhanced distributed channel access (EDCA) and the HCF controlled channel access (HCCA). The introduction of two CAMs increases the complexity of traffic management, since now not only the available resources have to be distributed, but also the optimal CAM for each data flow has to be selected. However, the best CAM selection algorithm is still not clear. This paper presents and analyses different CAM selection policies in order to derive the best-suited strategy in terms of system performance. From this study, an optimal policy, based on traffic type and direction (uplink or downlink), is proposed. The best user QoS satisfaction shown in the results confirms the good performance of this new selection policy. View full abstract»

  • Policy based RRM for network-terminal decision sharing

    This paper presents a policy-based radio resource management model for decision sharing between the network and the mobile terminals in the context of composite networks. One of the key issues discussed in this paper is the distribution of Radio Resource Management (RRM) decision making between the network and the mobile terminal. IEEE P1900.4 standard project proposes a policy-based radio resource usage scheme, where the decision-making is shared between the network and the mobile terminals. The network orients the mobile terminals decisions by sending rules and constraints. Mobile terminals choose the most appropriate action to their own Quality of service (QoS) objectives, within the action set allowed by the network. We define detailed scenarios illustrating this model. In addition, we propose a model where policies are chosen automatically act aiding to the variations of the environment conditions and the operator strategy. For this purpose, we define a policy database that stores the different environment configurations matched with the appropriate policies. Environment configurations are first classified. Then for each environment class an optimization algorithm finds the policy that fits the operator objectives. View full abstract»

  • 60 GHz wireless communications: emerging requirements and design recommendations

    Page(s): 41 - 50

    Multiple GHz of internationally available, unlicensed spectrum surrounding the 60 GHz carrier frequency has the ability to accommodate high-throughput wireless communications. While the size and availability of this free spectrum make it very attractive for wireless applications, 60 GHz implementations must overcome many challenges. For example, the high attenuation and directional nature of the 60 GHz wireless channel as well as limited gain amplifiers and excessive phase noise in 60 GHz transceivers are explicit implementation difficulties. The challenges associated with this channel motivate commercial deployment of short-range wireless local area networks, wireless personal area networks, and vehicular networks. In this paper we detail design tradeoffs for algorithms in the 60 GHz physical layer including modulation, equalization, and space-time processing. The discussion is enhanced by considering the limitations in circuit design, characteristics of the effective wireless channel (including antennas), and performance requirements to support current and next generation 60 GHz wireless communication applications.
