As traffic congestion is becoming an everyday facing problem in urban region, traffic prediction and detection systems are playing an important role in city life. The road network sensors were popular in the previous systems. However, these technologies addressed to solve the installation and maintenance cost. Fortunately, the dramatic technology innovation is carrying many crucial solution for transportation...
The need and use of scalable storage on cloud has rapidly increased in last few years. Organizations need large amount of storage for their operational data and backups. To address this need, high performance storage servers for cloud computing are the ultimate solution, but they are very expensive. Therefore we propose efficient cloud storage system by using inexpensive and commodity computer nodes...
Cloud is a relatively new concept and so it is unsurprising that the information assurance, data protection, network security and privacy concerns have yet to be fully addressed. The cloud allows users to avoid upfront hardware and software investments, gain flexibility, collaborate with others, and take advantage of the sophisticated services. However, security is a huge issue for cloud users especially...
Integration processes gain in importance today. Service-oriented Architecture plays a vital role in the modern design of business and academic IT landscapes. The integration of services still remains among the hard SOA challenges. The need for addressing them becomes more pressing with the increase in the number of online (cloud) services. This system also defines the possible scenarios to focus the...
Cloud computing is deployed a large set of virtualized computing resources in different infrastructures and various development platforms. One of the significant issues in cloud computing system is the scheduling of virtual resources and virtual machines (VMs). To address this issue, this paper proposed an efficient approach for virtual machines scheduling in VM management also called EVMSA (Efficient...
The widespread popularity of Cloud computing as a preferred platform for the deployment of web applications has resulted in an enormous number of applications moving to the cloud, and the huge success of cloud service providers. The data center storage management plays a vital role in cloud computing environments. Especially the PC cluster-based data storage is necessary to manage data on low cost...
Grid access control mechanism is aimed at verifying the identity of an entity, controlling certificates and to restrict from unauthorized accesses to grid resources. Hence, it plays a vital role to get the system availability as well as to prevent the attackers who tries to get the unauthorized accesses to resources. In fact, this paper proposes the system that provides the secure certificate framework...
A wide range of applications are hungry for high performance computing (HPC). Commodity workstation/PC clusters represents a cost-effective platform for scalable parallel computation. The message passing mechanism is usually employed for interprocess communication in a cluster for data sharing and process synchronization. In high performance computing, the most widely-used standard for interprocess...
Today the Internet is predominantly based on IPv4. As a result, most of the end systems and network devices are able to exchange packets all together in a global network. But IPv4 was not developed to accommodate such a magnitude and broad range of use, so it has various problems including a limited address space and security issues. So IPv6 (Internet protocol version 6) has been developed based on...
Ubiquitous computing envisions an environment where physical and digital devices are seamlessly integrated. But migration is one of the critical issues of ubiquitous computing across the different applications because of heterogeneous resources. Hence, mobile applications must adapt to changing contexts and resource availabilities as they migrate from one environment to the next. The most of ubiquitous...
Various multicast applications and transmission control protocols have a common requirement of content-based transmission. The Internet applications manage a large and widely-dispersed set of users, have multiple data streams that vary in content and media type, and make use of multiple unicast and multicast streams in a single session. The current IP multicast service and architecture do not efficiently...
Mobile agent technique involves distributed control if communication among different types of network, especially when it can migrate from station to station. Mobile agent technology' has the ability to travel from host to host in a network and to places of their own choosing at times. If motivates force in reducing network traffic and overcoming network latency and their ability to operate asynchronously...
In this paper, we propose the design of an extension of the Java distributed object model based on the group communication paradigm for building replicated fault-tolerant servers. Maintaining the correctness and integrity of replicated servers is supported by the group manager object instantiated with each replica to form a logical group and the group membership algorithms to maintain a consistent...
Parallel query processing is an increasingly attractive option for improving the performance of database systems. It can also be important in grids since grid technologies have enabled sophisticated interaction and data sharing between resources that may belong to different departments or organizations. The decreasing cost of computing makes parallel query processing economically viable to reduce...
The distributed objects are built inevitably by client/server systems. They are essentially objects, which can be processed and stored, anywhere on a network. In theory, applications should be able to easily access distributed objects, no matter what they are. This is good, given the growth of client/server computing which spreads from single server departmental local area networks (LAN) to wide area...
A parallel program is composed of multiple processes, each of which is to perform one or more tasks defined by the program. The optimization objective for partitioning is to balance the workload among processes and to minimize the interprocess communication needs. Its primary goal is to ensure that no processor is idle while there are processes waiting for services in other processors. Mobile agent...
