Performance Evaluation of Gauss-Markov Mobility Model in Hybrid LTE-VANET Networks
Abstract: Vehicular Ad-hoc
Network (VANET) is developed based on mobile ad-hoc networks (MANET). VANET has
different characteristics than MANET. On VANET, a mobile node (MN) moves
faster, topologychanges dynamically. The previous research shows that the model
of mobility affects to the networkperformance. In this paper, a Gauss-Markov
mobility model is used to illustrate the motion of the MN. This paper enriches
the evaluation of the performance of Gauss-Markov mobility model on LTE-VANET
hybrid network, by evaluating various network performance metrics, i.e. packet
delivery ratio (PDR), throughput, and delay. This research simulates the
Gauss-Markov mobility model with various numbers of nodes and randomness index
(α), using Network Simulator-3 (NS-3). The result shows that strong correlation
amongPDR, throughput, and delay with the addition number of MNs. Based on the
simulation result, the hybrid LTE-VANET have smaller 40% average delay than the
existing VANET. This simulation also concludes that different value of alpha on
Gauss-Markov mobility model does not influence PDR, throughput, and delay.
