TL;DR: This is the first scheduling algorithm for a multihop network based on the IEEE 802.16 mesh mode standard, and the results will aid network designers in fine-tuning the details of the communication system for satisfactory performance in the field.
Abstract: Demand for broadband access networks has grown rapidly with the increased demand for Internet connectivity and multimedia services. Fixed broadband wireless access systems based on the IEEE 802.16 standard may become a viable alternative to wired systems. In particular, the mesh networking capability added into the standard will potentially provide significantly wider broadband wireless coverage without requiring line-of-sight. In this paper, we present a transmission scheduling algorithm for the IEEE 802.16 mesh mode standard. To the best of the authors' knowledge, this is the first scheduling algorithm for a multihop network based on the 802.16 standard. Simulation results show that the proposed algorithm achieves high channel efficiency while providing equal transmission opportunity (i.e., fair access) to all nodes in the network. This study will aid network designers in fine-tuning the details of the communication system for satisfactory performance in the field

TL;DR: The design of a plug-in for the optimized link state routing (OLSR) protocol with the expected transmission time (ETT) metric and experiments in an indoor testbed are presented, showing that the ETT metric has the lowest packet loss rate and the lowest round trip time among the analyzed metrics.
Abstract: This paper presents the design of a plug-in for the optimized link state routing (OLSR) protocol with the expected transmission time (ETT) metric and experiments in an indoor testbed. The ETT metric is implemented as a plug-in, keeping portability and facilitating its deployment on operational networks. Our design identifies important implementation issues. Additionally, we run experiments in an indoor testbed to verify the performance of our ETT plug-in. Our results show that the ETT metric has the lowest packet loss rate and the lowest round trip time among the analyzed metrics, because it reproduces link quality conditions and also takes into account physical transmission rates.

TL;DR: This work analyses a set of network traces from the Linknet wireless network in Zambia, which provides Internet access to approximately 300 residents of a rural village using a satellite link and a combination of point-to-point links, hotspots and wireless mesh networks.
Abstract: There have been a number of rural wireless networks providing Internet access over the last decade but little is known about how the Internet is being used, how these networks perform and whether they follow similar trends when compared with Internet usage patterns in developed regions. We analyse a set of network traces from the Linknet wireless network in Zambia, which provides Internet access to approximately 300 residents of a rural village using a satellite link and a combination of point-to-point links, hotspots and wireless mesh networks. Our analysis reveals largely web-based traffic as opposed to the peer-to-peer traffic dominance that one finds in urban areas. Social networking sites receive the most hits, and large file downloads from operating system repositories contribute the most to the bandwidth consumption. A number of network pathologies in the gateway as well as the wireless mesh network are also analysed and a set of recommendations conclude the work.

TL;DR: It is concluded that both static and dynamic channel allocation strategies have advantages and disadvantages, and the design of channel allocation algorithms strongly depends on the interference model and the assumption of network traffic.

TL;DR: The background and recent activities in the area of energy sustainable WLAN mesh networks are reviewed, and recent work is reviewed that has begun to address the changes that would be required to the standard to better support these types of networks.
Abstract: Wireless LAN mesh networks are now being used to deploy Wi-Fi coverage in a wide variety of outdoor applications. In these types of networks, conventional WLAN mesh nodes must be operated using continuous electrical power connections. This requirement may often be very expensive, especially when the network includes expansive outdoor wireless coverage areas. An alternative is to operate some of the WLAN mesh nodes using an energy sustainable source such as solar or wind power. This eliminates the need for a fixed power connection, making the node truly tetherless and allowing more flexibility in node positioning. In this article we first review the background and recent activities in the area of energy sustainable WLAN mesh networks. These types of networks are provisioned geographically, in that the assigned resources are a function of the geographic region where the network is to be deployed. The theory behind this is briefly described using some sample North American locations. We then discuss the current shortcomings of IEEE 802.1 1 when used in these types of networks. IEEE 802.11 requires that the access point be continuously powered, and this requirement is a major barrier to deploying cost-effective sustainable energy networks in certain applications. Recent work is then reviewed that has begun to address the changes that would be required to the standard to better support these types of networks.
