We introduce LiPS, a new cost-efficient data and task co-scheduler for MapReduce in a cloud environment. By using linear programming to simultaneously co-schedule data and tasks, LiPS helps to achieve minimized dollar cost globally. We evaluated LiPS both analytically and on Amazon EC2 in order to measure actual dollar charges. The results were significant; LiPS saved 62–81% of the dollar costs when...
Although the probabilistic model checking tool called PRISM had been applied in many communication systems, such as wireless local area network, Bluetooth, and ZigBee, the technique is not used in a controller area network (CAN). In this paper, we use PRISM to model the mechanism of priority messages for CAN because the mechanism lets CAN as leader in serial communication for automobile and industry...
This paper presents a new desynchronization algorithm aimed at providing collision-free transmission scheduling for single-hop and acyclic multi-hop wireless sensor networks. The desynchronization approach is resilient to the hidden terminal problem and topology changes. Each node distributively converges upon a single collision-free transmission slot, utilizing only minimal neighbor information....
