Networks

Abstract – It is well-known that the throughput of wireless mesh networks without frequency re-use decreases as O(1/N), where N is the number of nodes in the network. In this paper we build on this result and obtain expressions for calculating the throughput in IEEE 802.11-based mesh networks without interference. Both expressions for single-frequency and multi-frequency mesh networks are obtained. We compare the analytical results with measurements of the UDP throughput in a real IEEE 802.11 mesh network, and show that our analytical expressions can closely approximate the throughput in real mesh networks.
