摘要

针对如何提高车辆自组织网络无线信道资源利用率问题

提出了一种分布式车辆间通信信道接入控制算法

该算法具体表示为利用中国余数定理设计一种用户保障协议序列

车辆节点(亦称用户)依据该协议序列决定其对通信信道的接入

无需基站或中心节点的协调

所设计的协议序列确保每个车辆节点在一个序列周期内至少成功发送一次数据.仿真结果表明

采用本文提出的协议序列控制算法比无反馈时隙ALOHA接入控制算法具有更小的传输时延

能够满足车辆自组织网络通信实时性的要求.

Abstract

A distributed medium access control algorithm applied in vehicular ad hoc networks is presented to improve the utilization rate of wireless channel.It includes the construction of a kind of user irrepressibility protocol sequence based on Chinese Remainder Theorem

and the assignment of the protocol sequences to the vehicular nodes which are also called users.The vehicular nodes transmit or receive the packet according to the assigned sequences instead of the coordination by base station or access point.The designed user irrepressibility protocol sequences can guarantee that each vehicular user can successfully transmit a packet within a period.The simulation results show that the transmission delay under the control of protocol sequences mentioned is less than that of slotted ALOHA.
