The large amount of data collected in the Internet of Things (IoT) need to be transmitted to servers for processing in order to provide various services. Due to the limited amount of resources in IoT, including network bandwidth, node processing abilities, and server capacities, congestion control in IoT plays a crucial role for meeting service performance requirements. In this paper, we propose a...
For a lot of producers have never saved materials of their products for aims of economizing their time and saving costs, but when they have received orders, they will start from their locations with their production lines travel first to the material supply regions, second to the ordered regions, and product their products on the travelling time. Here, we consider their minimum travelling time routing...
We consider an investment problem where n possible entries are to be selected by a single investment company.There is a capital resource limition C for the company.For every possibly selected entry i ∈ {1, 2, ··· , n},there is a required operation capital Oi, a market life Li,a required operation finished time Ti and a currently potential profit Pi which could be only obtained by the company Pi {(1...
Motivated by the results of rational objective functions on spanning tree, assignment and cycle cover problems, etc. We consider rational objective functions with fixed scale subset problems which includes spanning tree, assignment and cycle cover problems. We design a preprocessing algorithm for it, and prove that our algorithm improves the result of N. Megiddo and the result of M. Shigeno, Y. Saruwatari,...
Composite Web services are often long-running, loosely coupled and cross-organizational applications. They always run in a highly dynamic environment. For the applications and environment, advanced transaction support is required to ensure the quality of reliable execution. Towards composite service adaptive mechanism unavailable for lacking transaction support, this paper proposes a self-healing...
Web services can be composed together and interact with each other to carry out complex transactions or workflows. During the execution of an autonomic process, if one component service fails or becomes overloaded, a mechanism is needed to ensure that the running process is not interrupted and the failed service is quickly and efficiently replaced. This paper presents a novel Web services replacement...
