The area of trustworthy charging in self-organized environments has been developed quite recently. These components introduces a new secure charging-protocol, the polynomial-assisted charging protocol, for ad-hoc environments. The protocol relies on polynomial composition for speeding the identification process in small groups. It is able to provide strict guarantees of cooperative behaviour in traffic forwarding, with minimal network overhead.
It can be used for identification of routes and charging in ad-hoc, or any other multi-hop scenario.
