Abstract

In wireless networks, raising the throughput and decreasing the network delay are always themain goals to solve. This paper studied the relationship between Contend Window and Backoff Time, and raised the BEEB algorithm in which the Backoff time obeys the exponential distribution and the idea of active nodes. The BEEB algorithm can effectively improve the default that nodes choose long defer time and access the channel slowly, and can shorten the idle time and decrease the time to acquire the channel by accelerating the collision process. The performance analysis and simulation results show the active-nodes can decrease the MAC access delay and increase the network throughput using BEEB algorithm.
