The Heterogeneous Wireless Networks (HWN) is a type of framework which includes different varieties of wireless technologies. To ensure a robust management and a reliable behavior of HWN, it is necessary to well manage the interworking between its technologies and in particular to secure interworking and roaming between the 3rd Generation Partnership Project (3GPP)/Long Term Evolution (LTE) and Wireless Local Mesh Networks. A whole of solutions has been proposed to solve this problem; we quote mainly Extensible Authentication Protocol-Authentication and Key Agreement (EAP-AKA) which still suffers from some vulnerabilities such as, man-in-the-middle attack, Sequence Number (SQN) synchronization, and disclosure of user identity. In this paper, we propose new re-authentication protocol. The suggested solution proves its effectiveness following the studies of simulation which carried out according to different criteria handoff latency, loss and blocking rate.
