The solution for the difficulty in providing users wide band spectrums very complicated due to its increase in access points brings burden on backhaul links. So the alternate one is that D2D communication, it is a caching based process thereby improves spectrum efficiency. In previous applications attribute mobility of user is ignored, where as in D2D communication it plays a major role. Here the mobility attribute improves practical approach with the user. By considering mobility of a user data off-loading ratio is increasing, where data-offloading ratio defines the throughput via cellular links over D2D communicational links. The computation of caching process is very complex, so it is solved through many methods. Initially it is a NP-hard caching placement problem, by solving through many methods such as. With Optimal Dynamic Programming Algorithm, the performance reaches benchmark, unlike in exhaustive search its complexity is almost minimized. Solution generated is monotone submodular maximization, which is in the form of matroid constraint. The conventional solution for monotone submodular maximization over matroid constraint is greedy algorithm. Using joint caching the data offloading ratio is increased because of the consideration of both file cache and location cache in a single unit. The advantage of joint caching is it matches with real time data sets as showed in simulation results. In the joint caching algorithm, it shows as the user mobility is high or low it caches most popular files, the user with medium mobility caches minimum popular files in order to get rid of duplication.
