Wireless Sensor Networks (WSNs) are made of a large amount of small devices that are able to sense changes in the environment, and communicate these changes throughout the network. An example of such network is a photo voltaic (PV) power plant, where there is a sensor connected to each solar panel. Because such a network covers a large area, the number of sensors can be very large. The task of each...
Users increasingly own multiple devices with a number of network interfaces. These devices support different communications technologies that enable the creation of multi-technology Personal Area Networks (PANs). Yet, without a routing solution, connectivity between any two devices in the PAN is not guaranteed. State of the art PAN routing solutions are complex, do not guarantee shortest routes, and...
This paper quantifies the impact of topological characteristics on the performance of single radio multichannel IEEE 802.11 mesh networks. Topological characteristics are the number of nodes per subnetwork, the hop count, the neighbor node density, the hidden nodes, the number of nodes in the neighborhood of the gateway, and the hidden nodes in the neighborhood of the gateway. Network performance...
P2P Video Streaming has become a reliable and efficient solution for distributing video on the Internet. Similarly to regular P2P file-sharing, all the participating nodes exchange information. Wireless Mesh Networks, in turn, can be seen as a cost-effective solution to extend Internet access networks. In this paper we propose improvements to P2P Video Streaming. These improvements can provide gains...
