A service level model and Internet mobility monitorSpringer Science and Business Media LLC - Tập 37 - Trang 49-70 - 2008
Christer Åhlund, Stefan Wallin, Karl Andersson, Robert Brännström
Mobility is gaining a tremendous interest among Internet users and wireless access networks are increasingly being installed to enable mobile usage. Internet mobility requires solutions to move between access networks with maintained network connectivity. Seamless mobility in turn means that the experience of using a service is unaffected while being mobile. Communication in next generation networ...... hiện toàn bộ
Full-duplex protocol for vehicle-to-vehicle NOMA relay system over double Rayleigh fadingSpringer Science and Business Media LLC - Tập 80 - Trang 337-347 - 2022
Ta Chi Hieu, Nguyen Le Cuong, Ba Cao Nguyen, Pham Thanh Hiep
In this paper, we combine two new techniques: non-orthogonal multiple access (NOMA) and full-duplex (FD) in a downlink of wireless cooperative relay communication system with two end users. The NOMA approach is applied to both the source and the relay. Whereas, the FD is only applied to the relay. The system performance is investigated in the case of vehicle-to-vehicle (V2V) communication. The sel...... hiện toàn bộ
Modeling and improving the throughput of vehicular networks using cache enabled RSUsSpringer Science and Business Media LLC - Tập 70 - Trang 391-404 - 2018
Saeid Akhavan Bitaghsir, Ahmad Khonsari
Newly emerged applications in vehicular networks demand high throughput to transfer large amount of data through both Vehicle-to-Vehicle and Vehicle-to-Infrastructure links. One solution which recently draws researchers attention to itself for improving the throughput in this type of network is to deploy some Road-Side-Units (RSUs) in the streets with storage capability and store the data closer t...... hiện toàn bộ

Performance analysis and fault tolerance of randomized routing on Clos networksSpringer Science and Business Media LLC - Tập 10 - Trang 157-173 - 1998
Manjit Bhatia, Abdou Youssef
Beside universality and very low latency, Youssef's randomized self-routing algorithms [25] have high tolerance for multiple faults and more strikingly have the potential for fault tolerance without diagnosis. In this paper we study the performance of Youssef's routing algorithms for faulty Clos networks in the presence of multiple faults in multiple columns with and without fault detection. We sh...... hiện toàn bộ
Scheme for improving transmission performance of realtime traffic using priority queues in HMIPv6Springer Science and Business Media LLC - Tập 36 - Trang 3-11 - 2007
Wongil Park, Jonghyoun Choi, Byunggi Kim
Hierarchical Mobile IPv6 (HMIPv6) has been proposed by the Internet Engineering Task Force (IETF) to reduce handoff latency and signaling overhead. In the new protocol, Mobility Anchor Point (MAP) receives all packets in place of Mobile Node (MN) and MAP services are transferred to Care of Address (CoA) of MN. However, a MAP may be a single point of performance bottleneck because the MAP should n...... hiện toàn bộ
Symbol error rate on fading self-interference channel in full-duplexSpringer Science and Business Media LLC - Tập 67 - Trang 477-483 - 2017
Fei Wu, Donglin Liu, Youxi Tang
In-band full-duplex (FD) is being considered as a promising technology for the next generation wireless communication systems. In this paper, the performance of orthogonal frequency division multiplexing (OFDM) modulation system with different symbol duration and the code spreading system with different spreading sequence lengths under time-varying self-interference (SI) channel in FD mode is inve...... hiện toàn bộ
Implementation and efficiency analysis of composite DNS-metric for dynamic server selectionSpringer Science and Business Media LLC - Tập 71 - Trang 1-18 - 2018
Drazen Tomic, Drago Zagar, Goran Martinovic
User requirements for a high availability and fast response time of network services require placing more than one server for accessing particular network service, often using multiple communication links and locations. Dynamic Server Selection (DSS) is a new DNS method for the optimal server selection of a multiple available network service that allows dynamic selection of a server on the client ...... hiện toàn bộ
Topology sense and graph-based TSG: efficient wireless ad hoc routing protocol for WANETSpringer Science and Business Media LLC - - 2017
Abd Alrazak Tareq Rahem, Mahamod Ismail, Ihab Ahmed Najm, Mohammed Balfaqih
Technologies such as wireless ad hoc have undergone rapid redesigning. The routing protocol plays an essential role in improving the performance of wireless networks. However, improving the routing efficiency of a WANET still faces two main challenging issues: the routing table size and routing protocol selection criteria from the source to destination. This paper propose an efficient routing prot...... hiện toàn bộ
