An interference elimination method for decentralized slot synchronization in TDMA-based wireless Ad Hoc network

Time slot synchronization is very important for a TDMA- based ad hoc network. An existing method to achieve time slot synchronization in ad hoc network is the decentralized slot synchronization algorithm. However, interference nodes in the network may lead to un-convergence of this algorithm. In this paper, a method for eliminating the interference in decentralized slot synchronization is presented. To evaluate the performance of the proposed mechanism, the influence to the convergence of slot synchronization in the network is investigated. Simulation results indicate that, with this method, the interference is effectively eliminated from the computation of decentralized slot synchronization.
