Wireless mesh networks are one of the most important improvements in the world of wireless technologies. In fact, they offer many advantages to ensure a free mobility and a self-configuration of the various network equipment, a better quality of services, as well as an extensible domain and area. In spite of all of these contributions, mesh technology still suffers from some problems such as security especially in handoff phases. In this study, we propose an authentication scheme that is designed to reduce the authentication delay during a wireless mesh network handoff process. The proposed mechanism takes into account the mobility of clients as well as the router movements. This work takes advantage of some existing techniques such as Blom key predistribution scheme and Du key process generation method. Our simulation results prove the effectiveness of our proposed scheme. Our performance evaluation results shows that the suggested solution outperforms existing schemes in improving handoff latency values (<15 ms) and in the ability of satisfying the requirements of security as well as the quality of services in terms of having low loss rate (less than 1%) and having a low blocking rate.
