We must re-design identifier, directory service, trust model, routing and communication model for the computer system and computer networks. For example, Delay Tolerant Networking (DTN) or Peer-to-Peer (P2P) system architecture would challenge the introduction of new technological frameworks to the existing Internet. Finally, this paper discusses how to build and how to deploy the future Internet infrastructure while describing the Green University of Tokyo Project. Copyright © 2010 John Wiley & Sons, Ltd.

This paper describes the architecture and operations of a test system NGNAS-SIOTP. NGNAS-SIOTP is designed based on the Testing and Test Control Notation Version 3 (TTCN-3) specifications for the conformance testing of next generation network applications and systems. By specifying conformance test cases at abstract level, the test cases are language and platform-independent, and the implementation of the test cases can be more convenient.

A hierarchical convergence mechanism for the heterogeneous RANs is presented, where the heterogeneous cooperative relay selection, maximal-ratio combining, multi-user diversity schemes are designed jointed. A closed-form outage probability and symbol error rate expressions and their approximated formulas are derived, and they shows that a full diversity order approximately equals to (KJN_D–KJ+1) can be achieved, where N_D is the antenna number of destination nodes, K and J are the number of destination nodes and relay nodes, respectively.

This paper addresses new basis of piecewise-quadratic Harmut functions to eliminate weak convergence, discontinuity and others problems as an examples of analytically set and experimentally verified dependences. The advantages of piecewise-quadratic bases are greater accuracy and smoother approximation, in comparison with piecewise-constant and piecewise-linear bases. The proposed system and algorithm could find wide application in such areas as computer graphics, image processing and restoration, machine vision and multimedia, animation and programming of computer games.

In this paper, we propose a cooperative spectrum sensing scheme in the presence of reporting errors in cognitive radio networks. Accurate local sensing results may not directly be applied to cooperative sensing due to reporting errors. We consider the cooperative spectrum sensing that utilizes local sensing results in good reporting channel condition. Finally, simulation results show that the proposed scheme can maximize the detection probability while guaranteeing the desired false alarm probability. Copyright © 2010 John Wiley & Sons, Ltd.

This paper proposes an IPTV service architecture for the IMS combining centralized control and peer-to-peer-like streaming, where the UEs from the customers' premises act as forwarding nodes. In order to achieve response times comparable to currently deployed systems, we introduce the idea of foster peers that have inactive multimedia sessions. These peers are on stand-by until their functionality is required, at which moment they can accept downstream peers for events requiring urgent treatment like channel change and recovery.

This paper proposes a novel, totally distributed solution for data federation, where authorization, management of data localization and synchronization of federated data are thought to be part of the meta information that may be associated with each data element. The paper explains how this can be achieved through the combination of two existing complementary standards. Copyright © 2009 John Wiley & Sons, Ltd.

This paper defines a new mechanism, named Basic Connectivity (BC) mechanism, for autoconfiguring IP connectivity between attaching devices or networks. A proof-of-concept prototype, experimental results, and theoretical analysis show that BC suits the future networking paradigm and represents a solution more efficient than the current trial-and-error mechanism for autoconfiguring IP connectivity.

We have developed a compound algorithm for efficient packet classification by combining the techniques of cross-producting and tuple space search. The new algorithm allows filters to be stored either in a cross-product table or a tuple space to avoid the overwhelmingly large number of cross-product entries by limiting the size of the cross-product table. Our experimental results show that our scheme could better balance the speed and storage performance, especially for large filter databases. Copyright © 2009 John Wiley & Sons, Ltd.

This article describes enhancements to the 3GPP EPC/PCC framework that discover signaling routes at the service control layer and use this information to determine paths traversed by media at the resource control layer to provision end-to-end QoS enabled paths. This approach is compatible with existing transport networks and exploits already existing QoS control mechanisms. The architecture is implemented and evaluated in a real testbed implementation, comprising free and open source software. Copyright © 2010 John Wiley & Sons, Ltd.

In this paper, we propose and analyze a threshold-based CAC scheme. The scheme is a generalized and enhanced version of the GC scheme where the GC scheme is modified to be applicable for different traffic classes with different QoS requirements in wireless cellular networks. Our specific objective in designing the scheme is reducing the blocking and dropping probabilities, while efficiently maintaining bandwidth utilization. The scheme is modeled as a Markov birth-death M/M/C/C queuing discipline model. Copyright © 2010 John Wiley & Sons, Ltd.

We present a QoS-aware fair packet scheduling (QFPS) algorithm to fulfill the QoS provisioning for distributed IEEE 802.16 mesh network. We take advantage of the distributed scheduling mechanism dictated in the standard and design a hierarchical QoS scheduling structure to guarantee the end-to-end delay of the traffic flows with time-urgent requirements. Moreover, a new fairness model among different traffic flows is also implemented in QFPS to schedule traffic flows fairly. Copyright © 2009 John Wiley & Sons, Ltd.
