Hossein Falaki, Dimitrios Lymberopoulos, Ratul Mahajan, Srikanth Kandula, Deborah Estrin
2010 Proceedings of the 10th annual conference on Internet measurement - IMC '10  
Using data from 43 users across two platforms, we present a detailed look at smartphone traffic.  ...  We show that while packet loss is the main factor that limits the throughput of smartphone traffic, larger send buffers at Internet servers can improve the throughput of a quarter of the transfers.  ...  CONCLUSIONS Based on monitoring the devices of 43 users, we presented a detailed look at smartphone traffic.  ...

All or none? The dilemma of handling WiFi broadcast traffic in smartphone suspend mode

Ge Peng, Gang Zhou, David T. Nguyen, Xin Qi
2015 2015 IEEE Conference on Computer Communications (INFOCOM)  
We find that on some smartphones, WiFi broadcast frames interrupt suspend mode and force the phone to switch to active mode (>120mW). As a result, power consumption increases dramatically.  ...  So, we have a dilemma of handling WiFi broadcast traffic during smartphone suspend mode: either receive all of them suffering high power consumption, or receive none of them sacrificing functionalities  ...  At first, the phone is in suspend mode with very low power consumption (∼11mW).  ...
