The opportunistic networks and the bike-sharing systems have been attracting much research attention in these years. In this paper. the cycling trips and the buffers of bike stations are utilized to relay the large volume of data. The Markov chain is exploited to formulate and estimate the delivery ratio with the mathematical lattice model. https://www.lightemupsequences.com/quick-find-Our-Seasons-The-World-in-Winter-Spring-Summer-and-Autumn-best-save/
