摘要：

In order to allocate the bandwidth to satisfy consumer's requirement dynamically and equitably in a wireless communication network, an improved bandwidth allocation algorithm based on the typical token bucket is proposed. In this algorithm the token buckets are divided into virtual sub-token buckets corresponding to the number of the consumers. Furthermore, the leaky buckets are added behind the token bucket to reallocate the bandwidth occupied by consumers. The consumer priority and weight are also set. The simulation results show that the improved algorithm can effectively enhance the throughput of wireless communication network. Not only the common consumers can equitably achieve the bandwidthresource, but also the special requirement of the important consumers can be satisfied.
