Libra, a Multi-hop Radio Network Bandwidth Market

Rasmusson, Lars and Janson, Sverker (2007) Libra, a Multi-hop Radio Network Bandwidth Market. In: 7th Scandinavian Workshop on Wireless Ad-hoc & Sensor Networks (ADHOC'07), 2-3 May 2007, Stockholm, Sweden.



Libra is a two-level market which assigns fractional shares of time to the transmitting nodes in local regions of a multi-hop network. In Libra, users are assigned budgets by management and users assign funding to services within their budget limits. The purpose is to prioritize users and also optimize network utilization by preventing source nodes from injecting too much traffic into the network and thereby causing downstream packet loss. All transmitting nodes sell capacity in the region surrounding them, and buy capacity from their neighbors in order to be able to transmit. Streams buy capacity from each of the nodes on their paths, thus streams that cross the same region compete directly for the bandwidth in that region. Prices are adjusted incrementally on both levels.
