The E-business under the pattern of cloud computing has much of advantages and prominent features, which will be confronted with a variety of issues about security just like the current E-business. This article introduces the conception and trait about the E-business under the pattern of cloud computing in brief and puts forward the security threats from the perversion of data security, the criterion...
This paper proposes a new mechanism, multi-connection from heterogeneous networks in IP multimedia subsystem (IMS). With the appearance of IMS, multimedia service has become an important service, which needs high bandwidth and low delay. But the network, which can match these features simultaneously, doesn't exist. In order to provide robust, high-quality services in IMS, we utilize the character...
In the current IP Multimedia Subsystem (IMS), the service triggering is mainly executed by the Serving-Call Session Control Function (S-CSCF) according to the information included in the initial Filter Criteria (iFC) which is stored in the Home Subscriber Server (HSS). In this paper, after analyzing the defects of the current mechanism, we propose a new service triggering mechanism: State based Service...
In theory, the paper presents an Automated Negotiation Model by applying negotiation strategies and utility function. In methodology, the paper establishes a negotiation mechanism which can improve both the automated processing flow and the automated trade by using agent technology. At last, simulate the process of Electronic Commerce automated negotiation and analyze the output of the program on...
AODV on-demand routing protocol is widely deployed in ad hoc network, but it has some drawbacks. This paper proposes an improved AODV protocol called AODV-I. By adding the congestion processing to the RREQ message and the routing repair mechanism to the RREQ message, the new protocol not only reduces the packet loss rate and the end-to-end latency, but also enhances the utilization rate of the network...
