A network shadow fading model for autonomous infrastructure wireless networks

In traditional cellular networks the base stations (BSs) are more or less regularly deployed. In the channel model for such networks, correlated channel gains are only considered between a BS and multiple terminals (or one terminal and multiple BSs). Although the literature has introduced efficient techniques to produce correlated channel gains, to our knowledge it has not reported on the correlation between pairs of links with no common end. This may be a reasonable model for large cell sizes (or equivalently the large inter-site-distances) in the traditional networks. In future networks, however, it is expected that a large number of BSs will be deployed in random positions. With the dense deployment of BSs, appropriate correlation channel models should be developed. This paper proposes a novel shadow fading model which enables the generation of correlated shadow fading gains between all links in the network.
