This paper investigates the performance of multihop virtual multiple-input-multiple-output systems (V-MIMO), based on the concept of virtual antenna array (VAA), in the presence of random location of nodes. Nodes are supposed to be distributed according to a Poisson point process. Random fluctuations are considered, and the channel model takes both slow and fast fading into account. Performance is evaluated in terms of outage probability, which is defined as the probability that the ergodic capacity between the source and the destination is smaller than a given threshold. We investigate the impact of a random distribution of nodes on the overall performance. The role played by the interference, when some reuse of radio resources is considered for inter-VAA communication, is also investigated.
