Leveraging ICN In-network Control for Loss Detection and Recovery in Wireless Mobile networks
ACM-ICN '16: Proceedings of the 3rd ACM Conference on Information-Centric NetworkingPages 50–59https://doi.org/10.1145/2984356.2984361One of the most appealing features of Information-Centric Networking (ICN) is its agile connectionless transport model based on consumer requests and hop-by-hop forwarding. By relaxing end-to-end constraints, ICN empowers a distributed in-network ...

Active caching: a transmission method to guarantee desired communication reliability in wireless sensor networks
IEEE Communications Letters (CL), Volume 13, Issue 6Pages 378–380https://doi.org/10.1109/LCOMM.2009.090023Due to the high packet loss rate during multi-hop transmissions in wireless sensor networks, more reliable end-to-end data transmission is desirable. Because wireless sensor network applications require various levels of communication reliability (CR), ...

Design a hierarchical cache system for effective loss recovery in reliable multicast
APPT'07: Proceedings of the 7th international conference on Advanced parallel processing technologiesPages 423–432Packet loss recovery is a key issue in reliable multicast. An effective way for packet loss recovery is to place repair servers with active routers along the transmission paths. These repair servers naturally form a hierarchical cache system due to the ...
