abstract = "In this work1, we consider a mobile distributed MIMO architecture, where the communicating nodes continuously recruit clusters of adjacent transmit and receive nodes to operate as mobile and temporary antenna arrays. As the channel conditions change due to node mobility, the clusters are reconfigured to best serve the communicating nodes. The reconfiguration rate depends on the required system performance, exhibiting a tradeoff between performance and complexity. Our results show that there is an optimal number of transmit nodes (out of the nodes with most favorable channel conditions) to maximize the system achievable rate, which we quantify by closed-form expressions. With the nodes being modeled as Brownian motions, the time interval to reselect a new transmit cluster is obtained analytically and serves to estimate the order of magnitude of the required cluster reselection time for a practical random walk models.",
