为解决Ad-Hoc多源端和多目的端场景下已有的传输群调度机制通信冲突严重的问题,分析了Ad-Hoc网络中多对多场景下传输群中不同传输区域发生事件F和事件F’k(k=2,3,4)的概率,在基于两跳的f-cast中继算法的基础上设计了一种适用于多对多场景下的传输群调度机制,该传输机制根据上述两种事件发生的概率来调整相应区域内小区成为可通信小区的概率.理论分析和仿真结果表明,提出的传输群通信调度机制在多对多通信场景下可以有效地减少通信冲突发生的概率,提高网络通信能力.
In order to solve the problem of communication conflicts in the existing transport group scheduling mechanism under the multi-source and multi-destination scenario of Ad-Hoc, the event F and event F Based on the two-hop f-cast relay algorithm, we design a scheduling mechanism of transport group which is suitable for many-to-many scenario. According to the above-mentioned The probability of two kinds of events happening is adjusted to adjust the probability that a cell becomes a communicable cell in the corresponding area.Theoretical analysis and simulation results show that the proposed scheduling mechanism of communication group can effectively reduce the probability of communication conflict in the case of many- Improve network communication ability.
