In this paper, the authors propose an algorithm for coexistence in TVWS between IEEE 802.22 and IEEE 802.11af by equal opportunity without increased delay time and decreased throughput, for each of them. Also, an investigation has been conducted for the coexistence problem between the 802.22 and the IEEE 802.11af systems, in the TV White Spaces (TVWSs). IEEE 802.22 and IEEE 802.11af are two typical standards envisioned to be widely adopted in the future. However, these two standards are heterogeneous in both power level and PHY/MAC design; as a result coexistence challenge is there.
