One of the paramount advantages multi-level cache-enabled (MLCE) networks is pushing contents proximity to network edge and proactively caching them at multiple transmitters (i.e., small base-stations (SBSs), unmanned aerial vehicles (UAVs), device-to-device (CE-D2D) users). As such, fronthaul congestion between a core large number alleviated. We consider throughput maximization problem that op...

This paper presents a review on energy efficient clustering protocols for heterogeneous wireless sensor network. Energy consumption is the critical design issue in the wireless sensor network since each node has a battery and each battery has limited lifetime. Therefore using the battery in efficient way became an important task for prolonging the lifetime and stability of the wireless sensor n...

Heterogeneous information networks (HINs) are widely applied to recommendation systems due their capability of modeling various auxiliary with meta-paths. However, existing HIN-based models usually fuse the from meta-paths by simple weighted sum or concatenation, which limits performance improvement because it lacks interest compositions among In this article, we propose an Interest Composition...
