Seamless Handoff through Information Retrieval in VANET Using Mobile Agent
Nowadays, everything is moving towards the infrastructure less
wireless environment to bring the smartness of the society. In this
situation, it is necessary to bring the smart technologies in the adhoc
network environment. As vehicular traffic is a foremost
problem in modern cities and on highway. Huge amount of time
and resources are wasted while traveling due to traffic congestion.
VANET is providing comfort and safety for passengers.
Moreover, various transactions like information on accident, road
condition, petrol bank details, menu in the restaurant, and discount
sales can be provided to the drivers and passengers. The speed and
time in which the message is sent and received plays an essential
part in the Intelligent Transport System (ITS). For this the
VANET requires efficient and reliable methods for data
communication, gathering and retrieving information for seamless
handoff in VANET. In this paper we discusses the architecture of
VANET consists clusters that’s designed by mobile agents having
instantaneous conditions of Mobile Nodes available in VANET.
For efficient data communication, an attempt has been made to
create a new clustering concept with the help of mobile agents
among the VANET nodes. Subsequently for smooth and seamless
handoff we have considered the call admission control mechanism
with the help of Genetic algorithms applied over information
retrieval system managed by mobile agent with the effect of
shadowing for reducing the data overhead over VANET.
