Abstract

A Bandwidth reservation is an essential component in providing of quality of service (QoS) in vehicular ad hoc networking (VANENTs). The recommended MAC protocol for VANET experiences a high percentage of packet loss. Somehow its performance can be improved by using Time Division Multiple Access (TDMA) techniques. In this paper, we propose a new algorithm for multi-constrained QoS routing and show how to enhance the guarantees for bandwidth reservation based on TDMA environment where the bandwidth is expressed in terms of the number of time slots. We introduce stability scheme to identify stable links based on the neighborhood availability information in several different normal and TDMA-based scenarios. Simulation results show a great promise for network improvement in TDMA-based scenario for packet delivery ratio with up to 64.5% increase compared to normal scenario. In terms of packet loss, TDMA-based scenario performs better with as much as 47.2% decrease compared to the normal scenario.

增强的带宽预留对车载网络QoS路由的保证

在车载自组织网络(VANENTs)中，带宽预留是提供服务质量(QoS)的重要组成部分。推荐的VANET MAC协议丢包率很高。采用时分多址(TDMA)技术可以在一定程度上提高其性能。本文提出了一种新的多约束QoS路由算法，并展示了如何在以时隙数表示带宽的TDMA环境下增强对带宽保留的保证。在几种不同的基于正常和tdma的场景下，我们引入了基于邻域可用性信息的稳定性方案来识别稳定链路。仿真结果表明，在基于tdma的场景下，网络的分组传输率比普通场景提高了64.5%，有很大的改善前景。在丢包方面，基于tdma的场景性能更好，丢包率比普通场景降低了47.2%。
