| 摘 要： | 针对采用网状网模式组网的WMAN中,提出一种由移动站电量余量决定的分配优先级的系统带宽分配算法,按需分配网络资源并提高网络整体性能问题。通过提高重要节点收发数据时的时间集中度,降低重要节点收发数据时的功率消耗,较大程度降低了重复迭代计算的算法复杂度。该算法可以通过启发式分配等效可分配时间和发射功率来优化系统的资源分配,亦还可以通过改变效用函数的斜度参数满足不同的业务特性。

| Abstract: | To solve the demand assignment problem of bandwidth allocation and improve the system overall performance in WMAN MESH mode,a bandwidth allocation algorithm based on the priority weighting,which was decided by residual capacity of battery of mobile station,was proposed to significantly decrease computational complexity.The proposed algorithm may optimize resource allocation according to traffic characteristics by allocation rate,power efficiency and the inclination parameters of the utility function which can be flexibly shifted to meet different traffic characteristics demand. |
