Defined by the 3GPP, the IP multimedia subsystem (IMS) is an architectural framework that enables the delivery of multimedia services in mobile networks. Based on the session initiation protocol, the IMS offers unified billing, QoS negotiation mechanisms, and the possibility of combining services deployed in different environments like CAMEL and Parlay OSA. With the aim of determining the real limitations...
A new query intensive interface information extraction protocol (QIIIEP) for deep Web retrieval process is proposed. Auto query word extraction and auto form unification procedure are newly proposed in order to comprehend various functions of the proposed protocol. Proposed protocol offers great advantages in deep Web crawling without over burdening the requesting server. However, conventional deep...
Among the various forms of malware, botnets are emerging as the most serious threat against cyber-security as they provide a distributed platform for several illegal activities such as launching distributed denial of service attacks against critical targets, malware dissemination, phishing, and click fraud. The defining characteristic of botnets is the use of command and control channels through which...
In P2P networks, an economic measure is efficient to incentivize nodes to provide services to others. As the payment scheme is essential in the economic measure, an efficient and secure payment scheme is our goal. In this paper, we propose a mechanism that requires the nodes first purchase enough trivial scrip and then pay a piece of scrip for each service, such as a file piece (say 256 KBytes) downloading...
Information services are one of the most important requirements of the grid system. They include Discovery and Monitoring of the resources. The discovery is the process of finding the computational resource/service. The Monitoring detects and diagnoses problems. Both require the information collection about the resources from the complete grid environment. This paper intends to explore some mechanisms...
