Cooperative group provisioning with latency guarantees in multi-cloud deployments

Sean Yaw, Eben Howard, Brendan Mumey, Mike P. Wittie
2015 Computer communication review  
Here, we formally define the Cooperative Group Provisioning problem and show it is NP-hard to approximate within a constant factor.  ...  We find that multi-cloud deployments dramatically increase the likelihood of meeting group latency thresholds with minimal cost increase compared to single-cloud deployments.  ...  The process then loops back and determines the path costs for the paths of the remaining clients. This algorithm is presented as Algorithm 1.  ...

JiTS: Just-in-Time Scheduling for Real-Time Sensor Data Dissemination [article]

Ke Liu, Nael Abu-Ghazaleh, Kyoung-Don Kang
2006 arXiv   pre-print
Based on this observation, we propose a Just-in-Time Scheduling (JiTS) algorithm for scheduling data transmissions to alleviate the shortcomings of the existing solutions.  ...  We show that the shortest path routing using the minimum number of hops leads to considerably better performance than Geographical Forwarding, which has often been used in existing real-time data dissemination  ...  In contrast, the proposed Just-in-Time Scheduling (JiTS) approach sets target transmission times for the packets in accordance with their deadline and the remaining distance along the path.  ...

New Insights into the Real-time Performance of a Multicore Processor

Raimarius Delgado, Byoung Wook Choi
2020 IEEE Access  
We identify various multicore deployments and discuss their trade-offs, as established through the experimental evaluation of the scheduling latency.  ...  In real-time systems, where processes and tasks are governed by stringent temporal constraints, the worst-case timings should be considered, and migration to multicore processors leads to additional difficulties  ...  Nonetheless, the scheduling latency should remain low to ensure that the real-time tasks are schedulable and exhibit deterministic behavior.  ...
