The introduction of of web services has led to web service composition being a focus of many researchers. Composing web services using workflows is seen as the most realistic method from an industrial view-point. Amongst other method, the use of natural computing methods has been proposed previously to automate web service composition. The need for a fast response when computing the most suitable sequence of services is addressed in this paper. In particular, we propose a novel heuristic immune algorithm with an efficient encoding and mutation method. The algorithm involves two steps: an immune selection operation, which is maintaining antibody population diversity and the clonal selection. The use of a vaccine during the evolution provides heuristic information that accelerates the convergence. Our experimental results illustrate that the proposed heuristic immune algorithm is very effective in improving the convergence speed. We also provide a schema analysis for this method.

As a network-based mobility management solution, Proxy Mobile IPv6 (PMIPv6) has been adopted by IETF, 3GPP and WiMAX to complement the host-based approach. In PMIPv6, the Local Mobility Anchor (LMA) is introduced to perform the mobility management and data forwarding, thus achieving the transparent mobility support. However, it results in the sub optimal routing path and single node failure. To realize the optimal routing and separate the forwarding function from the LMA, several routing optimization solutions have been proposed, but most of them are based on the MIPv6 built-in route optimization mechanism or MAGs tunnel, which incurs the additional overhead. In this paper, we propose a PMIPv6 route optimization solution based on the Identify/Location Split mechanism. Especially, in the proposed solution, a Location Identifier (LID) is assigned to each mobile node and mapped to its Home network Prefix (HNP) to accomplish the optimal routing and reduce the additional tunnel overhead. The analytical results show that the proposed scheme is better than other schemes in terms of signaling cost, delivery cost and LMA service blocking probability. © 2012 IEEE.

Existing Web services composition technology, lack of services selecting. A particle swarm optimization algorithm based on the multi-objective optimization strategies was provided to address quality of services to choose the issue of global optimization. It is to transform Web services select the overall optimization problem with QoS into a multi-objective constrained optimization problem based on Qos, using multi-objective PSO intelligent theory, by a number of Qos parameters optimized at the same time, and ultimately produce a set of constraints to meet the Pareto optimal solution. The experimental results show the feasibility and efficiency of the algorithm.

Content-Centric network (CCN) as one of the well-known Information Center network (ICN) solutions has been getting more and more research recently. Different to the traditional Internet which is designed to connect the different terminals, CCN mainly focuses on the content delivery by enhancing the cache function of routers. However, in case of the interworking between the CCN and traditional Internet, we should carefully select the locations of CCN routers so that all the end users can get the better performance. So in this paper, we propose an evaluation metric called average content acquirement time based on the complex network centralities including the degree centrality, closeness centrality, betweenness centrality and eigenvector centrality to selection the location to acquire the tradeoff between deployment cost and service performance. We evaluate the average content acquirement time under different network centralities, and the results shows that the betweenness centrality has the better performance than others, and it can be used as a metric to select the location of CCR routers.

In order to ensure the correctness and reliability of Web services composition based on OWL-S, verify the interaction protocol of Web services. It is provided that three lay architecture. Composition service based on OWL-S, GA model is the middle model and the Promela model is the verification model, SPIN as a model validator. The OWL-S composition Web services transform a top-down conversation protocol process into a GA model, use WAST tool into Promela model, the SPIN tool analysis and verification structure and performance of composition services. This method is flexibility and scalability which provide a solution for Web services composition model verification.

The Cognitive Internet as a new Internet architecture with cognition capability was proposed based on the cognitive radio technology and new network architecture. Cognitive Internet has two kinds of users called Cognitive Users (CUs) and Primary Users (PUs). The CUs can occupy the frequency of PUs when they are absent. As a result, the activities of CUs may have an important impact on the PUs. So in this paper, we model the movement behavior of CU under the random direction mobility model, and analyze its expected hitting time between CU and PU to evaluate its potential impact. Besides, we simulate the mobility of CU to acquire the expected hitting times, and compare it with the analytical results. The final results show that the analytical results can fit with the simulation results.

Web service technology has been proposed to implement management interfaces of managed resources, but the efficiency of the Web service based network management system is influenced. With the development of semantic Web, this paper proposes to apply semantic Web service technology to the network management. In order to promote the efficiency of network management system and reusability of network management functions, an approach to define and execute composite network management processes with existing technology has been presented. Performance management service as a case is described using OWL-S, then services composited by OWL-S Editor.
