IEEE 802.16 specifications for the mesh mode require the handing over Mesh Client (MC) to process the network entry procedure and to authenticate with the mesh Base Station (BS) in order to issue its request and to be scheduled for data transmission. Besides, the mesh BS does not reserve resources for serving the active connections belonging to the handing over nodes. In this paper, we aim at optimizing the management of handing over MCs. First, we define a number of reserved timeslots so that the handing over stations can rapidly issue the requests relative to active connections and can begin data transmission before the network entry process termination. The number of reserved timeslots will be updated according to the load in order to add more flexibility and minimize the possible waste of resources. Besides, the handing over stations will be able to use the reserved timeslots even after registration. We also propose some mechanisms for addressing the collision, fairness and security issues induced by our scheme.
