In this paper we present a protocol performing on demand distributed channel selection in multi channel, multi interface wireless mesh networks, based on the exchange of control messages. The link based channel reservation happens almost instantly when data traffic is sent through the network, and does not require long-term traffic profiles or measurements.(More)
In this paper we present a cross layer topology preserving channel selection protocol for a two interface wireless mesh network. The presented protocol is a cluster driven channel selection protocol, preserving a single interface to maintain connectivity and using the other interface to participate in small clusters. The clusters are organized by an(More)
Simulations have always been a very useful and powerful tool to study and develop networking protocols. <i>ns-2</i> is one of the most commonly used open-source network simulators and many protocols have been evaluated with this tool. In order to bridge the gap between simulation and implementation on a real testbed, <i>Nsclick</i> was developed.(More)
Computer-enhanced smart environments, distributed environmental monitoring, wireless communication, energy conservation and sustainable technologies, ubiquitous access to Internet-located data and services, user mobility and innovation as a tool for service differentiation are all significant contemporary research subjects and societal developments.

The technical evolution of Wi-Fi networks has made it possible to attain very high speeds for delivering content to users. However multicast transmissions never received the same level of attention as unicast transmissions in the IEEE802.11n standard. In this paper, we experimentally assess the viability of employing commercially available IEEE802.11n(More)
The mobility of an ad hoc network can severely degrade the performance of the wireless network, as a direct consequence of frequently occurring link break events. An ad hoc routing protocol must react swiftly to these events by recomputing the forwarding table. Typical routing protocols rely on a timeout mechanism to notify a failing link. This causes a gap(More)
