– This paper addresses Wireless Campus project as a WLAN service deployment and test-field development experience. Will be covered aspects about the network, administrative issues and infrastructure and RF coverage. Then will be given details about security problems and solution proposed and mobility issues. Finally will be presented our solution proposal… (More)
We address the joint problem of traffic routing and mobility support in wireless mesh networks that are built by many fixed nodes and few mobile nodes. We focus on a vehicular setting, where buses or streetcars connect to different fixed mesh nodes as they move in a urban environment. First, through simulation we identify the best candidate for routing… (More)
This paper presents a route management protocol for multi-homed infrastructured WMNs aiming to preserve active sessions of mobile nodes. Every mesh access point (MAP) has at least one MAP interface configured as a traditional AP and another one dedicated to the WMN backhaul. The clients are mesh-unaware to avoid installing special software on them. We… (More)
Vehicular networks are expected to support both safety and non-safety applications, through Dedicated Short Range Communications (DSRC) in 5-GHz bands. These channels, however, are of limited capacity and recent studies have high-lighted their scarcity, in comparison to the broad range of services that are envisioned in vehicular networks. We therefore… (More)
In this paper we described UbiquiTO, an agent-based system that acts as an expert tourist guide for mobile users, providing different information according to the device, the user and the context. The system uses feedbacks coming from localization to acquire the knowledge required to provide location-based services and to update the user model.
Mobile ad hoc networking allows the development of several infrastructure free applications. One of the arguments we focused on is the possibility of deploying a set of services in areas lacking of low-cost and wide band connectivity to Internet, as rural or mountain communities. The main idea is that it is possible to transfer data by mobile vehicles such… (More)
Evaluating the available bandwidth in a wireless LAN is a challenging task because the throughput depends on several factors such as RSSI (Received Signal Strength Indication), interferers and packet size. Moreover, in a real scenario it is not sufficient to evaluate periodically the throughput of the network, but a continuous monitoring is required in… (More)
