The influence of transmission range on the performance of Vehicular AD-HOC Network (VANET)
Vehicular Ad-hoc Network (VANET) is a sub-class of Mobile Ad-hoc Network (MANET). The system has been developed to attain Dedicated Short Range Communication (DSRC) among vehicles (V2V) by consolidating existing technologies in which each vehicle is considered as a node. This type of communicati...

| 总结: | Vehicular Ad-hoc Network (VANET) is a sub-class of Mobile Ad-hoc Network
(MANET). The system has been developed to attain Dedicated Short Range
Communication (DSRC) among vehicles (V2V) by consolidating existing
technologies in which each vehicle is considered as a node. This type of
communication is part of an Intelligent Transportation System (ITS) application.
Importantly, there is still no comprehensive evaluation which portrays the mobility
impact on the IEEE 802.11p MAC protocol performance, especially for the V2V
communications between high mobility nodes. Moreover, the system performance
also subjected to various factors including the transmission range, traffic load and
number of flows that change rapidly in scenarios such as on highway. The main goal
of this dissertation is to evaluate the impact of those factors in VANETs environment
using AODV as routing protocol. In order to validate the simulation of VANET,
traffic and network simulators (SUMO & NS-2) have been used. The performance is
evaluated in terms of packet delivery ratio and end to end delay. The simulation
results showed that better performance can be achieved in term of higher PDR and
lower end to end delay when the transmission range is less than 500 meters. In
contrary, when the transmission range is more than 500 meters, PDR started to
decrease and end to end delay increased. The performance also degraded as the
number of flows increased. |
