Many believe that Cloud will reshape the entire ICT industry as a revolution. In this paper, we aim to pinpoint the challenges and issues of Cloud computing. We first discuss two related computing paradigms - Service-Oriented Computing and Grid computing, and their relationships with Cloud computing. We then identify several challenges from the Cloud computing adoption perspective. Last, we will highlight...
With the proliferation of international standards for grid-enabled databases, the need for data loading and mapping is identified. It is required in a large integrated environment encompassing heterogeneous databases. This research study proposes an intermediate staging facility in order to upload and integrate data from various small to large size data repositories. The proposed facility has been...
Packet classification problem has received much attention and continued to be an important topic in recent years. In packet classification problem, each incoming packet should be classified into flows according to a set of pre-defined rules. Grid-of-tries (GoT) is one of the traditional algorithmic schemes for solving 2-dimensional packet classification problem. The advantage of GoT is that it uses...
In the process of a scientific experiment a workflow is executed multiple times using various values of the parameters of activities. For real-world workflows that may contain hundreds of activities, each having several parameters, it is practically not feasible to conduct a parameter sensitivity study by simply following a ”brute-force approach” (that is experimental evaluation of all possible cases)...
The following topics are dealt with: performance modelling; routing mechanism; distributed systems; parallel systems; service oriented architecture; communication technology; protocols; autonomic network systems; Internet computing; ad hoc networks; wireless sensor networks; privacy management; mobile networks; multimedia systems; pervasive computing; ubiquitous computing; security intrusion detection;...
Much work has been done to exploit the effectiveness and efficiency of job scheduling upon distributed computational--resources. With regard to existing resource topology and administrative constraints, scheduling approaches are designed for different hierarchic layers, for example, scheduling for job queues of local resource management systems (local scheduling), and scheduling for job queues of...
