STRUDEL: supporting trust in the dynamic establishment of peering coalitions

The Coalition Peering Domain (CPD) is a recent innovation within the field of mesh networking. It facilitates the management of community-area networks in a distributed and scalable form, allowing devices to pool their network resources (particularly egress links) to the common good. However, as in P2P systems, this form of cooperative sharing architecture raises significant concerns about the effect of free-riders: nodes that utilise the bandwidth of others without providing an adequate return to the community. To address this problem, we propose STRUDEL, a distributed framework that tackles the problem of free-riders and consists of: (i) a mechanism for the detection of malicious peers; (ii) a formal Bayesian trust model, to assess peers’ trustworthiness; (iii) a forwarding mechanism based on the maximisation of trust-informed utility.
