For e.g., disaster relief operations and sensor networks. Along with applications, we exhibit measurements to illustrate the advantages of our approach in dealing with transience.  ...  It achieves reliability and flexibility at the expense of throughput. It is ideal for scenarios where the reliability of connectivity is critical and bandwidth requirements are low.  ...  We are grateful to Mike Best, Ashok Jhunjhunwala and Shibu Mani for helpful discussions, to Sanjit Biswas for 50 Meraki nodes, and to the NCIIA for a sustainable vision grant supporting this work.  ...

A novel approach for making energy efficient PON

S.H. Shah Newaz, Ángel Cuevas, Gyu Myoung Lee, Noël Crespi, JunKyun Choi
2011 Proceedings of the ACM SIGCOMM 2011 conference on SIGCOMM - SIGCOMM '11  
In many cases, the OLT does not have any packets for the ONU and it goes to sleep again, what supposes a waste of energy.  ...  In this paper, we propose a novel Hybrid ONU that relies on a low-cost and low-energy technology, IEEE 802.15.4, to wake up those ONUs that are going to receive a packet.  ...  Figure 1 . 1 Listening procedure in the existing ONUs.
