Information Theoretic View on Hybrid Wireless Networks

The capacity of large hybrid wireless networks is considered in this project. The hybrid network is based on an ad-hoc network with an embedded wired infrastructure. Both types of wireless transmissions are allowed in hybrid networks: peer-to-peer and through infrastructure. The report focuses on the case when the number of base stations in the hybrid network grows sub-linearly with the network size. Previous results suggest that there exists a protocol that provides an improvement in capacity as compared to a pure ad-hoc network if the infrastructure growth is at least as fast as square root of the size of the network. In this work, we consider this problem from Information Theory point of view and derive the similar result for a general hybrid network without specifying any protocol.
