PoSiF: A Transient Content Caching and Replacement Scheme for ICN-IoT

Table 1

Comparison summary of ICN-IoT caching approach.

Paper	Approach	Parameter	Drawback
ICN in the IoT-NDN Wild [12]	Random	No parameter considered	Does not consider any parameters
Consumer-driven information freshness [29]	Random	Freshness	Other essential IoT parameters are not considered
Cache aware NDN in IoT [30]	Probabilistic	Freshness with cache time	Not taking content’s popularity into account
Probabilistic caching strategy for the internet of things [31]	Probabilistic	content freshness, energy level, and storage capability	Caching utility function may return a value even if one or more of its parameters are obsolete
Caching transient data [32]	Probability-based caching	Freshness and content popularity	Disregard content size
Lifetime-based cooperative caching (LCC) [33]	Cooperative caching scheme	Content popularity and freshness	Ignore the content and cache size parameters
DRL [34]	Deep neural network based	Content popularity and freshness	Cache size and content size parameters not considered
PUC [35]	Clustering	Content popularity and freshness	Content size not taken into account
CCS/CES [14]	Exponential weighted moving average (EWMA) and probabilistic	Freshness and popularity	Disregard essential IoT parameters like limited cache and content size not taken into account
