Performance evaluation of the mesh election procedure of ieee 802.16/wimax

IEEE 802.16 is a recent standard for Broadband Wireless Access networks, which includes a mesh mode operation for distributed channel access of peering nodes. In accordance with the IEEE 802.16 MAC protocol, time is partitioned into frames of fixed duration, each one divided into two sub-frames, for control and data transmission, respectively. Slots in the control sub-frame are used by nodes to negotiate the schedule of transmissions in data sub-frames, and are accessed by means of a collision-free distributed procedure, namely the mesh election procedure. In this paper, we analyze the performance of the mesh election procedure by means of extensive simulations, and identify the system configuration parameters that have the most impact on the performance of control message transmission. The analysis is carried out under the assumption that the wireless link is error-free.
