Performance Analysis of Multihop Relaying Caching for Internet of Things under Nakagami Channels

Performance Analysis of Multihop Relaying Caching for Internet of Things under Nakagami Channels

Performance analysis is studied in this paper for the wireless transmissions in Internet of Things (IoT) system, where both the direct link and the multihop relaying caching wireless transmission from the source node to the destination node are taken into the consideration. The key feature is the Na...
