  Abstract: Wireless device-to-device (D2D) caching has been recently introduced as an effective scheme for reducing the average download delay of mobile terminals (MTs) in cellular network. Specifically, the MTs first cache popular files in their local memories in off-peak hours and then exchange the requested files with each other in the vicinity via D2D communications during the peak hours. Prior works largely overlook MTs' heterogeneity in file preferences and their selfish behaviors. In this paper, we practically categorize the MTs into different interest groups according to their individual file preferences and jointly investigate each group's caching strategies to reduce the average file download delay. By modeling MTs' mobilities as homogeneous Poisson point processes (HPPPs), we analytically characterize MTs' average download delay in closed-form. We first consider the fully cooperative case where a centralizer helps all MT groups to make caching decisions. We formulate the problem as a weighted sum delay minimization problem, through which the minimum delay trade-offs of different groups are characterized. Next, we study two benchmark cases under selfish caching, namely, partial and no cooperation, with and without inter-group file sharing, respectively. The optimal caching distributions for these two cases are derived. Finally, extensive numerical examples are presented to compare the delay performances of different schemes and show the effectiveness of the cooperative D2D caching compared to the two benchmark cases.
