| Abstract: | With the increase of network service types and users broadband demand, Broadband Wireless Access(BWA) has become the focus of people’s attention. This paper introduces the Mesh mode of IEEE802.16, discusses congestion control in Mesh mode, and presents a new method through dynamically adjusting the exponent of transmission holdoff time and allocating minislot to control congestion. Simulation results show that the congestion can be controlled effectively, throughput is increased, packet loss rate and end-to-end delay are decreased. |

| Keywords: | IEEE802 16 technology Mesh networks congestion control exponent minislot |
