Understanding packet delivery performance in dense wireless sensor networks

Jerry Zhao, Ramesh Govindan
2003 Proceedings of the first international conference on Embedded networked sensor systems - SenSys '03  
From a networking perspective, the most basic aspect of wireless communication is the packet delivery performance: the spatio-temporal characteristics of packet loss, and its environmental dependence.  ...  These factors will deeply impact the performance of data acquisition from these networks.  ...  Finally, our experimental methodology itself is a first step towards a set of systematic techniques to study the performance of sensor networks in various environments.  ...

Hybrid Epidemics—A Case Study on Computer Worm Conficker

Changwang Zhang, Shi Zhou, Benjamin M. Chain, Gui-Quan Sun
2015 PLoS ONE  
The parameters of the model are inferred directly from network data obtained during the first day of the Conifcker epidemic.  ...  Conficker is a computer worm that erupted on the Internet in 2008. It is unique in combining three different spreading strategies: local probing, neighbourhood probing, and global probing.  ...  In this case, the mix of different spreading mechanisms is a critically condition for an outbreak (see Fig 1) . Recently we proposed a generic model to study the critically hybrid epidemics [16] .  ...

Enabling Embedded Inference Engine with ARM Compute Library: A Case Study [article]

Dawei Sun, Shaoshan Liu, Jean-Luc Gaudiot
2017 arXiv   pre-print
In this paper, we share our practical experiences of building an embedded inference engine using ARM Compute Library (ACL).  ...  Our conclusion is that, on embedded devices, we most likely will use very simple deep learning models for inference, and with well-developed building blocks such as ACL, it may be better in both performance  ...  However, this optimization comes at a cost: it introduces re-quantize and de-quantize operations. In Figure 4 , we compare the performance of two cases: quantization vs. without quantization.  ...
