With the maturity of SOA and rapid development of Internet, a new type of software delivery mode named SaaS (Software as a Service) which provides the customers functionalities needed arises. It saves the cost of IT operation and suits to the small to medium firms very much. Ecommerce has grown extraordinarily nowadays with widespread Internet usage. In order to make trades more convenient and faster,...
Wireless sensor networks (WSNs) have many applications in home and industrial automation, and the management and integration of WSNs into Internet and IP-based networks is still getting tremendous interesting. This paper presents a micro SOA-model as part of a 4-layered, SOA-based architecture targeting resource-constrained devices with 48 KB of ROM and 10 KB of RAM. The key idea in this model is...
Over the past three decades, the Internet has evolved from a point to point, open, academic network to an applications and services oriented critical infrastructure. The Internet has become a vital component of society today, from its simple origin as an academic research project. During this transition, numerous applications and usages of the network emerged that cannot be efficiently implemented...
Today, the B2B E-business systems in most enterprises usually have multiple heterogeneous and independent systems which are based on different platforms and operate in different functional departments. To deal with the increased services in future, an enterprise needs to expand its system continuously. This, however, will cause great inconvenience to the future system maintenance. To implement E-business...
This article outlines the necessity for federated service oriented testbeds in order to accommodate the requirements of future Internet research. Extensive investigations have been carried out in the networking and grid computing area during the last decades. These activities have successfully instantiated a number of large scale collaborative network testbeds and network emulation testbeds. The article...
More and more devices become network enabled and are integrated within one large, distributed system. The service-oriented paradigm is the main concept to implement this approach and to cope with the heterogeneity of the underlying network. However, resource constraints imposed by the underlying hardware, such as 8-bit micro controllers, require efficient protocols and often prohibit the use of technologies...
