Community wireless mesh networks are decentralized and cooperative structures with participation rules that define their freedom, openness and neutrality. The operation of these networks requires routing algorithms that may impose additional unnecessary technical restrictions in the determination of routes that can restrict the freedom of community users. The authors propose a receiver-driven discretionary routing mechanism where each receiver can freely specify delivery objectives and remain compatible with the collaborative approach of community networks. Each node has a unique identifier and can announce the description of its offer and also the description of its routing policy with preferences to deliver traffic to it.
