Relative Data Freshness of Asynchronous Communication Mechanisms

Lookup NU author(s): Agnes Madalinski, Dr Fei Xia, Professor Alex Yakovlev



Data freshness is an important property of asynchronous communication mechanisms (ACMs). It defines how up to date any item of data that the reader obtains from the ACM is. The concept of relative data freshness is introduced, which explores data freshness quantitatively. A method of studying relative data freshness for multi-slot ACMs using stochastic Petri nets (SPNs) techniques is presented. The relative data freshness properties of a three-slot and a four-slot ACM are investigated.
