Heterogeneous Multicast Networks with Wireless Helping Networks

Previously, it has been shown that wired infrastructures such as optical networks can improve the capacity of ad hoc wireless networks significantly. However, sometimes these wired infrastructures are too expensive or even infeasible. In this paper, we use wireless helping networks to enhance the throughput performance of ad hoc networks. We focus on heterogeneous multicast networks with wireless helping networks. The heterogeneity refers to the inhomogeneity of the distribution of the nodes. The helping networks are neither the sources nor the destinations of data flow. They only serve as relays of the data. The wireless helping networks can be regularly placed or randomly uniformly distributed or mobile. We derive achievable throughput for all these three cases. We also make a comparison between them and pure ad hoc networks without helping networks to see the contribution of wireless helping networks.
