Abstract
A Vehicular Ad hoc Network (VANET) is a distinctive situation of wireless ad hoc networks. The designing of the routing protocol considers a critical role in communication in VANET. VANET has specific features compared to other types of wireless ad hoc networks that impose special characteristics for designing of efficient routing protocols.The challenging factor in designing efficient routing protocols for VANET is the high movement of vehicles that incurs a rapid change in the network topology that causes frequent link breakage. This paper presents and evaluates different position-based routing protocols associated with VANETs. The evaluation aiming to determine appropriate specifications for optimal routing protocols’ features achieving best performance within different environmental conditions. The performance comparison is carried out in terms of Packet Delivery Rate (PDR), Void Problem Occurrence Rate (VPOR), and Average Hops Count (AHC).
Highlights
Vehicular ad hoc networks (VANETs) (Asim, R., Saira, G., Sana, A., & Amir, Q. 2017) are a particular category of wireless ad hoc networks
There is a shortage of in-depth performance evaluation of proposed position-based routing protocols that take into consideration the special features of VANETs.this research work compares and evaluates the latest position-based that were proposed to be suited to different VANETs environments
Shows void problem occurance rate Figure 3.shows the impact of mobility on surveyed routing protocols based on the selected performance metrics 6.1.2 Scenario 2 for Highway Environment In this scenario, the two communicating nodes travelling in opposite directions other participating nodes are travelling in both directions.In the second scenario for highway area, a constant number of 200 vehicles, and a diversity of movement velocities; 140, 120, 100, 80, and 60 Km/h were employed
Summary
Vehicular ad hoc networks (VANETs) (Asim, R., Saira, G., Sana, A., & Amir, Q. 2017) are a particular category of wireless ad hoc networks. The communication between participating nodes in VANET is executed through two modes. VANET applications are split into two categories: Safety based and non-safety-based applications The major contribution of this research concentrates on the V2V communication in VANETs. Further, unicast location-based routing protocols are the focal of this research.
