As the Internet of Things (IoT) has become a widespread phenomenon, promising sensor applications at the nanoscale have begun to emerge. One example is imaging via distributed massive nanoscale nodes (NSNs), which can be used to implement 'invisible surveillance cameras' by, for example, painting liquids containing nanoscale sensors onto walls. This imaging method requires periodic data transfer from thousands of NSNs to a data collection node (DCN). An essential technique for handling such transfers is the media access control (MAC) protocol. However, existing protocols cannot support periodic transfer from numerous NSNs because of inefficient communication caused by a large amount of headers in the packets. In this article, we introduce an original MAC protocol and discuss its capability in terms of implementing imaging applications. The proposed protocol applies a time-division access (TDA) feature to reduce the amount of headers and a two-layered protocol to enable simultaneous transmission among nodes. Slot assignment is an essential function in TDA and requires communication among nodes. Unlike existing methods, our simple approach enables communication by exploiting the unique features of the focused application. The results of the numerical simulation reveal that the proposed MAC protocol allows for periodic imaging with more than three thousand nodes and produces high-quality images very close to those obtained using ideal communication. These results are achieved by employing an original design framework to determine appropriate key parameters, such as the number of clusters and frame rate.

Three algorithms for multiuser mobility method are evaluated in terms of performance to derive the most suitable algorithms for different practical application scenarios. Traditional multiuser mobility methods focus on improving throughput performance only without considering algorithm execution overhead and complexity. In contrast to previous studies, this paper develops an analytical tradeoff framework for the throughput and algorithmic complexity evaluation based on multiuser cooperative mobility in Mobile Ad Hoc Networks (MANETs). On the one hand, we quantitatively derive and model the optimal strategy for optimization throughput. On the other hand, we jointly evaluate the complexity performance of proposed algorithms, which are demonstrated by the discrepancies in the number of users, movable range, and location distribution. Numerical simulations show that the game-theoretic algorithm provides 16.85% throughput gain with high user volume, the bound-algorithm offers 17.22% throughput gain at large movement ranges and the graph-algorithm can reduce 29.26% complexity, indicating the effectiveness of our proposed framework.
