基于TTL泛洪约束的移动拓扑控制方法

Mobile topology control method based on TTL flood constraint

移动拓扑控制技术就是将节点能够有控制地进行改动位置,针对移动网络中要保证信号的稳定和持续的连接,提出一种基于TTL泛洪约束的移动拓扑控制方法。首先引入TTL字段改进广播风暴的模型,改进后的算法解决了每转发一次,数据由1转为0的无法固定的问题,然后描述了算法的过程和程序设计,最后引入TTL算法进一步验证了节点的数量和投递率之间具有一定的正向相关关系。节点个数增加到一定程度时,广播次数曲线逐渐呈现平滑状态,节点传递的数量值和广播次数之间存在着一定的关系,以及得到TTL的值设定为5是最优化的选择。上述研究结果对于Ad Hoc网络在移动拓扑结构中具有实际应用价值。

Mobile topology control technology is able to control the nodes change position. To guarantee the stability and sustaining connection of the signals in mobile network, this paper presents a mobile topology control method based on TrL flood constraint. Firstly, the rilL field improved the broadcast storm model, the algorithm solves the question each forwarding once, the data from 1 to 0 are not fixed. Then, it describes the process and program design of the algorithm. Lastly, it further verifies with the TTL algorithm that some positive relationship exists between the number of nodes and the delivery rate, the number of nodes increase to a certain extent, the curves of the broadcast number become smooth state, there is a relationship between the number of nodes and broadcast transfer value, it gets the TTL value of 5 to be the best choice. The above results have a practical value for the Ad Hoc network untility in mobile topology.
