An Algorithm - EMD for Emergency in VANET
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2015, Vol 6, Issue 6
Abstract
Vehicular Ad hoc Networks [VANET] is one of the fastest emerging technologies for research as day to day many challenges and problem to be identified by the researchers before the technology becomes commercialized. Communication systems for vehicle largely developed by the increasing interest in intelligent transportation systems (ITS). Cooperative driving gathers information and shares it with other drivers, which can improve safety and efficiency by enabling vehicles to exchange emergency messages to other network node in the neighborhood and provide guidance to driver in making proper decision to avoid vehicle collisions and congestion. Message broadcasting or exchanging technique is mostly used among vehicles for disseminating safety type information. Message Dissemination over wireless networks arise many challenges like unreliability of link, message redundancy, hidden terminal and flooding or broadcast storm, etc., which mostly degrade the network performance. In emergency situations, there is small amount of time to make a handshake with other networks nodes, as the safety/emergency message is disseminating reliably and fast. Sending information is usually very costly and without Particular techniques result in serious data redundancy and collisions. This work focuses on effective approach that deals with broadcast storm problem for emergency message dissemination. For Simulation of result we can use SUMO and NS-2 Simulator.
