In this paper we proposed a topology control algorithm for the single channel wireless mesh network with m directional antennas equipped on each node. The objective of our algorithm is to maximize the traffic delivery ratio from each non-gateway node to gateway nodes, by adjusting the orientations of the directional antennas appropriately. By allowing each antenna connecting to multiple nodes, our...
Our goal is to propose a unified/generalized model for the Wireless Mesh Networks (WMNs) design problem taking into account all the parameters that have a significant impact on WMNs. In the WMNs design literature, different studies take into account traffic demand, interference, multi-channel, transmission power, potential locations of wireless routers/gateways and node's characteristics (number of...
In this paper, we perform an extensive measurement study on a multi-tier mesh network serving 4,000 users. Such dense mesh deployments have high levels of interaction across heterogeneous wireless links. We find that this heterogeneous backhaul consisting of data-carrying (forwarding) links and non- data-carrying (non-forwarding) links creates two key effects on performance. First, we show that low-rate...
Significant progress has been made in understanding the behavior of TCP and congestion-controlled traffic over multi- hop wireless networks. Despite these advances, however, no prior work identified severe throughput imbalances in the basic scenario of mesh networks, in which one-hop flows contend with two-hop flows for gateway access. In this paper, we demonstrate via real network measurements, test-bed...
