Abstract:
Vehicular Adhoc Network (VANET) is one of the interesting and advanced research
areas in sub domain of Mobile Adhoc Network (MANET) and due to its unique
features; it has attracted so much attention of both academia and industry. More
often than none, routing and how to secure the network has always been of utmost
priority to researchers and little attention is given to ensuring the efficient and
effective distribution of load in VANET for the purpose of reducing latency to the
minimum. However, with the advent of Intelligent Transport System (ITS) in pair
with the possibility of cloud and Internet of Things (IoT) in VANETs that support a
large spectrum of mobile distributed applications such as traffic alert dissemination,
dynamic route planning, context-aware advertisement and file sharing, there is need
for a system that will evenly distribute load in the network for the sole purpose of
latency reduction. This study thereby introduces a latency-aware model via a 3-tier
load distribution mechanism that reduces delay in message transmission and also
helps in addressing traffic congestion faster. The model links two or more Road Side
Units (RSUs) together via the internet such that each RSU services a VANET cloud
site by receiving, storing, transferring and redirecting messages from source to
target. The performance result of the developed model shows that the total distance
covered in each linked path increased optimally, the system has higher throughput
and was able to maintain a longer network life time
