N2 - Heterogeneous caching network consisting of edge servers and caching helpers is proposed to meet the huge amount of mobile traffic and provide low-latency caching services for users. The problem of caching redundancy caused by the overlapping of edge servers and caching helpers is neglected by most researchers. In this paper, we propose a spatially cooperative caching strategy to avoid the caching redundancy and improve the hit probability of the heterogeneous caching network. We analyze the performance of this caching strategy by using stochastic geometry, derive the optimal caching probability and make a comparison with available caching strategies. The numerical results show that, the proposed caching strategy has a better performance under the normal parameter settings.
