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...
IEEE 802.16 mesh mode is connection-less, and can not provide quality of service (QoS) according to different requirements of different data flows as Point-to-Multipoint (PMP) mode. In view of this problem, a new centralized scheduling mechanism to guarantee QoS of multiple services in IEEE 802.16 mesh network was proposed. In this mechanism, connections are classified into four classes, i.e., Unsolicited...
This paper firstly puts forward a two dimensional interworking authentication model between 3GPP and WiMAX. In the proposed model, EAP-AKA method is adopted, and the first registered 3GPP AAA server in home domain (i.e. HPLMN, Home Public Land Mobile Network) takes charge of the responsibility of authentication for 3GPP/WiMAX UE by using authentication vectors (AV) obtained from HSS (Home Subscriber...
According to the interworking authentication trends, this paper has proposed a novel reference of interworking AAA architecture among 3GPP, WiMAX and WLANs. Moreover, based on the proposed architecture, a hierarchy AAA mobility management architecture is brought forward, as well as a dynamic reorganizing management scheme authentication domain. Finally, the simulation results show that the total cost...
This paper is mainly focusing on the dynamic authentication data management for the heterogeneous interworking authentication among WiMAX and 3GPP. The 3GPP AAA server in HPLMN performs the authentication for the 3GPP/WiMAX UE by using the authentication vectors (AV) obtained from HSS. Moreover, when the 3GPP/WiMAX UE leaves and reenters the same PLMN (HPLMN or VPLMN) within its avaliable period of...
Based on EAP-AKA for different wireless access networks, this paper mainly focuses on the optimal authentication scheme. First, an optimized interworking authentication architecture is proposed among 3GPP, WLAN and WiMAX. Additionally, we present an authentication analytic model for 3GPP-WiMAX, pointing out that the authentication signaling cost can not only be affected by the k value of the authentication...
This paper presents a new method to use correlator in modern communications after analysing the application and performance of the traditional correlator in detail. According to the results of simulation, the new method have more precise frequency and timing synchronization in wireless communications, which improves its ability against interference of multipath and frequency selective fading. Even...
Facing the different wireless access networks, this paper has proposed several novel interworking AAA architectures among the 3GPP, WiMax and hotspot wireless LANs. In these architectures, a new entity named standby 3GPP AAA server is defined to cope with the single point failure. Moreover, based on the proposed interworking AAA architectures, a hierarchy AAA scheme is proposed. As a result, the simulation...
A scheme is proposed for adaptive antenna pattern switch in WiMAX (world interoperability for microwave access) system. In the scheme, the decision for switching is made according to the minimum acceptable signal-to-noise ratio. It enables the WiMAX system to switch adoptively between the multi-antenna pattern and the single antenna pattern. And then a proper tradeoff could be achieved between the...
