Quantum cryptography is one of the most promising technologies for guaranteeing the absolute security in communications over various advanced networks, including fiber networks and wireless networks. In particular, quantum key distribution is an efficient encryption scheme on implementing secure satellite communications between satellites and ground stations. However, it faces many new challenges ...Show More
Underwater acoustic communications have received significant research attention with the increasing ocean explore applications. Due to the frequency-dependent path loss and fading characteristics of the acoustic channel, and scarce available bandwidth, it is more important to employ frequency reuse scheme to improve the spectrum efficiency and the entire network performance. However, the frequency...Show More
In recent years, quantum-based techniques have attracted significant research attention because of its unique advantages on satellite communications, especially for security problem. Security guarantee is one of the most important requirements in QoS-driven 3D satellite networks. Quantum key distribution (QKD) is a methodology for generating and distributing random encryption keys using the princi...Show More
With the rapid advances in data transmission over various advanced underwater acoustic networks, it is important to develop the efficient protocol to obtain a high data-rate with QoS guarantee requirements for acoustic wireless communications. Because of the harsh underwater acoustic environments, such as time-varying network topology and channel conditions, limited bandwidth and constrained under...Show More
In recent years, the multiple-input-multiple-output (MIMO), the orthogonal frequency division multiplexing (OFD- and the relay communication techniques have significantly improved the important performance of radio wireless communication networks. Due to its wide and critical applications, we can also apply these techniques into the underwater acoustic (UWA) wireless networks. In this paper, we pr...Show More
Currently, the multiple-input-multiple-output (MIMO), the orthogonal frequency division multiplexing (OFDM), and relay technology have played a major role in radio-frequency (RF) communication networks, which have significantly improved the RF wireless network performance, such as spectrum efficiency, bit error rate (BER), and delay bound guarantee, etc. Based on their wide and crucial application...Show More
We propose the semi-Markov decision process (S-MDP) model-based stochastic optimization scheme for QoS-guaranteed services in orthogonal frequency division multiple access (OFDMA) multicell cooperation networks. Our objective is to efficiently maximize the power efficiency at the base stations while guaranteeing the diverse QoS provisionings for mobile users through the multicell cooperation resou...Show More

Multicell cooperation is emerging as a promising wireless communication technique to significantly improve the performance of cellular networks in terms of the coverage of high-datarate services and the system throughput for the next generation wireless networks. On the other hand, multicell cooperation also imposes the new challenges associated with the two mutually conflicting constraints betwee...Show More
QoS parameter mapping is a key technology with respect to guaranteeing QoS of business in heterogeneous networks dynamically. This paper studies a method for guarantee necessary End-to-End QoS for user satisfaction, focusing on the problem of quality of service (QoS) mapping between layers in a cascade. Due to the dynamic mapping of parameters, the consistency between user and network is guarantee...Show More
Continuously growing energy consumption in wireless cellular networks motivates the research towards energy saving approaches. Among previous works, many studies suggest different methods to reduce the transmission power for stationary wireless users. In this paper, we consider a challenging scenario which takes user mobility into account. Based on user mobility pattern, we propose the dynamic cel...Show More
Realization of end-to-end Quality of Service (QoS) provisioning in a scheme plays a very important role in improving stability and quality of communication. Although simple data switching is possible between heterogeneous networks supporting different QoS signalling, end-to-end QoS provisioning can not be completed due to different rules in executing resource reservation. In this paper, a dual-sta...Show More
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 c...Show More
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 o...Show More
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 s...Show More
