A Hidden Markov Model for Fault Tolerant Communication in VANETS

Abstract

The Ad-Hoc Network provides various advantages in vehicular communication. For efficient communication of vehicles, Vehicular Ad-Hoc Network (VANET) has proven to provide better communication between vehicles. There are several problems associated with vehicular communication. Communication failures often occur between vehicle to vehicle and vehicle to infrastructure [13]. To overcome these problem's Hidden Markov Model (HMM) is applied in VANET to improve intelligent vehicular communication. This model enables fault tolerant [15] communication by minimizing the communication failures and link failures while sharing resources among the vehicles. Hidden Markov Model consists of states and observations. In this model, the states are hidden, but the output of this model depends on the state. In this paper, we focus on Hidden Markov Model and how it is applied to VANET to improve the safer vehicular communication.
