考虑到实际系统中不同用户对通信有着不同的容量需求,为了在有限的频谱资源中获得更大的容量效果,提出一种嵌入式服务器软件接口通信容量调节算法。通过用户的信道增益信息,获取最小蜂窝用户数量。根据吞吐量增量降序排列结果,将排名靠前的蜂窝用户通信容量分配给用户对。将嵌入式服务器软件接口通信容量调节问题,转换为随机网络优化问题,对数据包码长和发送功率联合优化,引入离线算法的思想,提出通信容量调节算法,完成嵌入式服务器软件接口通信容量调节。实验结果表明,所提算法可以有效提升吞吐总量,同时能够有效降低平均等待调节延时,平均等待调节时延保持在30ms以内。

At present,different users have different capacity requirements for communication.In order to obtain bigger capacity in the limited spectrum resource,this paper presented an algorithm for adjusting communication capacity of embedded server software interface.Firstly,the minimum number of cellular users was obtained through the channel gain information.According to the descending order of throughput increment,the communication capacity of the top users was allocated to the user pair.Then,the communication capacity adjustment of embedded server software interface was converted into a random problem of network optimization.Moreover,packet code length and transmission power were optimized jointly.Meanwhile,the offline algorithm was introduced.Finally,a communication capacity adjustment algorithm was proposed.Thus,the adjustment for communication capacity of embedded server software interface was completed.The experimental results show that the proposed algorithm can effectively increase the total throughput while reducing the average queuing delay,and the queuing delay can be kept within 30ms.
