TL;DR: It is shown that the downstream throughput of a gateway node in a wireless mesh network can be improved by 10-35% under a variety of network topologies and traffic distributions, and the proposed approach requires only minor code change in the gateway nodes and does not require any additional hardware.
Abstract: In this paper, we consider the problem of mitigating interference and improving network capacity in wireless mesh networks from the angle of temporal-spatial diversity. In a nutshell, while the achievable throughput on a multihop wireless path is limited by intra-flow interference, the overall capacity of a multihop wireless network can be increased by exploiting temporal-spatial diversity of concurrent transmissions that exist among a number of wireless links. Connections that are routed along multihop wireless paths can be scheduled to take place simultaneously if their transmissions do not interfere with each other (significantly).To make a case of exploiting the temporal-spatial diversity to improve network capacity, we focus on transporting downstream traffic at gateway nodes with Internet access. We propose to construct, based on measurements of received signal strengths, a virtual coordinate system that is used to determine the sets of paths along which transmissions can take place with the least inter-flow interference. Based on the sets of non-interfering paths, the gateway node then determines the order with which a gateway node schedules frames of different connections to be transmitted. Through extensive simulation (with real-life measurement traces on an operational, city-wide wireless community network), we show that the downstream throughput of a gateway node in a wireless mesh network can be improved by 10-35% under a variety of network topologies and traffic distributions. This, coupled with the fact that the proposed approach requires only minor code change in the gateway nodes and does not require any additional hardware, makes it a viable option to improving network capacity in existing wireless mesh networks.

TL;DR: Using low cost network boards, home-built antennas and open source software the volunteers of the Wireless Leiden Foundation are able to lay-out an infrastructure for the inhabitants of Leiden at a very low cost.
Abstract: With the development of low cost hardware for wireless networking based on IEEE 802.11b, wireless networks are an emerging technology. Using these wireless techniques outdoors it is possible to build a community network not dependent on any provider. In the Netherlands such a network is being set up in and around Leiden. Using low cost network boards, home-built antennas and open source software the volunteers of the Wireless Leiden Foundation are able to lay-out an infrastructure for the inhabitants of Leiden at a very low cost. All kinds of applications (for profit and non-profit) are using this entirely wireless network.

TL;DR: An integrated presentation of applications, technologies and business models for wireless community network together with design considerations and examples is provided and a design methodology is suggested and illustrated to an ongoing digital city project in Hungary.
Abstract: In this paper we provide an integrated presentation of applications, technologies and business models for wireless community network together with design considerations and examples. An overview is given of the state-of-the-affairs of wireless community networks. Driving forces and stakeholders of the projects and the applications and services will be presented for some carefully selected cases. We suggest a design methodology and illustrate its application to an ongoing digital city project in Hungary. Relevant business models are also analyzed.

TL;DR: This work document the structure and evolution of one of the largest community wireless mesh networks worldwide, the Athens Wireless Metropolitan Network (AWMN), and focuses on how the network has grown in size, complexity and service offerings in the last few years.
Abstract: In recent years, we have witnessed a trend towards open wireless access, mainly driven by the low cost of IEEE 802.11-capable equipment and its operation in unlicensed spectrum. This trend has many faces; municipalities set up free Wi-Fi hotspots for Internet connectivity in public spaces, while Wi-Fi access is provided as an extra service to customers in other venues, such as restaurants or hotels. Also, in many metropolitan areas worldwide, communityinitiated wireless mesh networks have emerged. Their members use inexpensive technologies to build multi-hop wireless networks and communicate autonomously. In this work, we document the structure and evolution of one of the largest community wireless mesh networks worldwide, the Athens Wireless Metropolitan Network (AWMN). We focus on how the network has grown in size, complexity and service offerings in the last few years. To be able to dynamically discover the structure of such a network, we have developed a suitable topology discovery methodology.
