In the last years, the commercial deployment of data services in mobile networks has been evolving quickly, providing enhanced radio access technologies and more efficient network architectures.

Seguir leyendo arrow_right_altSpectrum scarcity and ever increasing densities of wireless network deployments have recently led to an opening of the 60 GHz millimeter-wave bands for unlicensed communication. In contrast to the previously used ISM bands below 5 GHz, a massive amount of 6-9 GHz of bandwidth is available at these frequencies. Usage of these resources is considered for wireless LAN and 5G cellular networks and with the ratification of the IEEE 802.11ad standard in December 2012, wireless LAN is about to bring millimeter-wave communication to the commercial market.

Seguir leyendo arrow_right_altMany data collection protocols have been proposed to cater for the energy-efficient flow of sensor data from distributed sources to a sink node. However, the transmission of control commands from the sink to one or only a small set of nodes in the network is generally unsupported by these protocols.

Because the interdomain routing protocol realizes contracts between Autonomous Systems (ASes), this paper argues that contractual and routing issues need to be tackled jointly to overcome the connectivity limitations. We propose Route Bazaar, a backward-compatible system for flexible Internet connectivity. Inspired by the decentralized construction of trust in cryptocurrencies, Route Bazaar uses a decentralized public ledger and cryptography to provide ASes with automatic means to form, establish, and verify end-to-end connectivity agreements.
