针对当前单兵作战系统通信网络中所采用的固定分配TDMA算法不能适应大型战场环境和自组织运行需求的问题，提出一种基于消费算法和二叉树时隙分配算法的动态时隙分配TDMA算法，即C-TDMA算法，通过多组载波监听消除接入冲突，在保证延时的基础上使用消费算法控制节点分组发送量，提高信道接入公平性，同时通过二叉树时隙分配算法支持网络分布式运行。仿真结果表明，对于负载较重、传输混合业务且时延敏感的单兵作战系统网络，该算法可以消除接入冲突，提高信道吞吐率。

The static slot allocation TDMA channel access algorithms used in Integrated Individual Soldier Combat System ( IISCS ) are not adaptable to the demand of large battlefield network and autonomous operation.To solve the problem,we proposed a dynamic slot allocation TDMA access algorithm of MAC protocol,named C-TDMA,based on consumption algorithm and binary tree slot allocation algorithm .The access conflicts are eliminated in the control slot by multiple RTS/CTS.The consumption arithmetic is used to control the data flow and improve fairness access of different services on the basis of delay quality,and the binary tree slot allocation algorithm is used for distributed network environment .The simulation results indicate that real-time services can be supported by C-TDMA protocol in heavy-load and mixed-service in IISCS,which presents good performance on access efficiency .
