Cooperation Enforcement in Mobile Ad hoc Networks with Centralized Supervision

摘要

Although individual node cooperation is necessary for the correct execution of network protocols in Mobile Ad hoc Networks, it is not always guaranteed. In this paper, we present a node reputation scheme aiming at detecting non-cooperative nodes in Mobile Ad hoc Networks with centralized control. This scheme was designed for CANA, an ad hoc enhancement to HIPERLAN/2, currently under development. Statistical methods for selecting the optimal parameters of the scheme are investigated and their efficiency is illustrated through theoretical analysis and simulation results.
