Network selection is one of the key issues in heterogeneous wireless networks. However, very few efforts have been made on both algorithm and management of network selection to satisfy the individual requirements of every single user, so as to attract customers in the future user centric business mode. This paper takes the following steps toward addressing this problem: 1) a novel user preference oriented network selection algorithm (UPNS) is proposed, by combining entropy theory and fuzzy analytic hierarchy process algorithm (FAHP); 2) a service level agreement (SLA) management model is designed for network selection control in heterogeneous wireless environment, mainly including the general function descriptions and a management model instance based on UPNS. Application scenario of the UPNS based instance is simulated. Results show its efficiency in satisfying users' individuality and maintaining user satisfaction.

    ABSTRACT: Load balance is a key technology in future heterogeneous wireless networks due to its merits like improving resource utilization, enlarging system capacity and providing QoS for users. This paper presents a load balancing scheme which is composed of QoS-based and load-related admission control and dynamic vertical handover. The scheme can provide better QoS and jointly optimize resource utilization. Simulation results show that the proposed scheme can provide better performance in packet loss rate and load balance than the traditional scheme which a user is admitted to the network with the least connections.

    ABSTRACT: The access network selection is important for the service delivery in a heterogeneous wireless environment. On the other hand, network coding can improve the transmission efficiency of wireless broadcasting. In this paper, we propose a network selection approach in the heterogeneous wireless broadcasting environment, whose key ideas are to combine the network selection with network coding and achieve a fast selection. Both theoretical analysis and simulation results show that the performance of our proposed approach is very close to the optimal approach based on network coding, but much faster. And our approach has a higher transmission rate compared with existing approaches.

    ABSTRACT: The increasing demand for broadband wireless service in today's wireless communications, especially with WiMAX technology being one of the 3G standards, is causing cellular network providers to consider the integration of different heterogeneous networks. Consequently, network selection techniques play a vital role in ensuring quality of service in heterogeneous networks. In this article we have developed a network selection scheme for an integrated 3G/WiMAX heterogeneous system. The design goal is to provide the user with the best available QoS at any time. The proposed algorithm selects network on the basis of available bandwidth estimation. Analysis of heterogeneous system with 3G and WiMAX network reveal that the proposed network selection method can effectively choose the suitable network by negotiating trade-offs among network dynamic condition and multimedia service application.
