A paper authored by Leonard Kleinrock and Fouad Tobagi—Packet switching in radio channels: Part I—Carrier sense multiple-access modes and their throughput-delay characteristics (1975 IEEE Transactions on Communications 23.12—has been awarded the inaugural SIGMOBILE Test of Time Award for 2016.

The Test of Time Award describes this paper as:  “A pioneering contribution to the early days of wireless packet networks that is on the reading list of any student interested in the foundation of media access control in packet radio networks. This paper makes a fundamental contribution to the development of carrier sense multiple access (CSMA) that underpins the wireless edge today.”
