Capacity of Wireless Hybrid Networks with Successive Interference Cancellation

In this paper, we investigate the capacity of wireless hybrid networks, in which a wired network of base stations is used to support long-range communications between wireless nodes. We introduce the multiple access technique by allowing more than one source node to transmit simultaneously and utilizing successive interference cancellation to decode information at the destination node. Our results show that, with the multiple access concept, the destination or the nearest base stations can receive information from the source nodes at rate O(b/n log (n/b)). But, when data is delivered to node, because the base station is the only transmitter in the cell, it can forward the message to each node only at rate Θ(b/n) and causes a bottleneck.
