“…With the simulating VA NET operational environment, two experimental settings were taken into account; the effects of diversity of participating vehicles number, and the diversity of vehicles' velocities. Evaluation cropped results in simulation environments have assured the efficiency of non-delay tolerant non-overlay position-based routing protocols in dynamic and dense environments which agrees with qualitative evaluation previously presented by (Singh, P. 2014, April), (Manvendra, S. 2015), (Ali, K., Phillips, I., & Yang, H. 2016, December). However, some deficiencies observed during the evaluation process should be considered by researchers.…”

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).

“…GPSR is best for delay sensitive networks because packets delivery take place with minimal latency. EAODV [18]: Researchers enhanced, modified and enrich AODV routing protocols for VANETs with establishing an acknowledgment technique among source and destination entities to ensure on time reception of data packets, and reduce loss of data packets. AODV was a reactive routing protocol, so when it needs to transmit data among nodes, it launched route discovery algorithm procedure.…”

VANETs an application of MANETs, a fast growing, promising and emerging technology provides basis for ITS following IEEE 802.11p standard based on DSRC designed for WAVE. VANETs enable communication among vehicles (V2V) and road side infrastructure (V2I), disseminating alert messages regarding road conditions and any other critical situation to ensure safety and avoid losses of precious lives and property. Due to high velocity of moving vehicles and dynamic speedy topology change ultimate optimum routing protocols is still a challenging task in VANETs. It is cleared from the proposed results that there is no such protocol that is best for all kind of evaluation criteria. Infact, each routing algorithm conduct differently in sense of performance metrics. In VANETs timely arrival of data is much important to handle the security threats or any emergency efficiently. In this paper we focused and inspected various routing protocols including AODV, DSR and DSDV for the purpose to find out protocols best suited for all scenarios. The comparison and evaluation of various routing protocols is done on the basis of different performance metric criteria like data throughput, PDR, end to end delay or latency and network stability etc.

“…1 illustrates short and long DBL and how it has an impact on application performance. This paper is an extension of our previous work [13] were three routing protocols were selected as a representative of reactive, proactive and geographically-based routing, AODV, OLSR and GPSR respectively, and evaluated through simulation. Our work considers these protocols in a realistic urban environment with two mobility models: an artificial map (Manhattan map) and two real world maps (part of the London congestion zone and part of the Leicester city centre).…”

Abstract-Networks performance is traditionally evaluated using packet delivery ratio (PDR) and latency (delay). We propose an addition mechanism the drop-burst length (DBL). Many traffic classes display varying application-level performance according to the pattern of drops, even if the PDR is similar. In this paper we study a number of VANET scenarios and evaluate them with these three metrics.Vehicular Ad-hoc Networks (VANETs) are an emerging class of Mobile Ad-hoc Network (MANETs) where nodes include both moving vehicles and fixed infrastructure. VANETs aim to make transportation systems more intelligent by sharing information to improve safety and comfort. Efficient and adaptive routing protocols are essential for achieving reliable and scalable network performance. However, routing in VANETs is challenging due to the frequent, high-speed movement of vehicles, which results in frequent network topology changes.Our simulations are carried out using NS2 (for network traffic) and SUMO (for vehicular movement) simulators, with scenarios configured to reflect real-world conditions. The results show that OLSR is able to achieve a best DBL performance and demonstrates higher PDR performance comparing to AODV and GPSR under low network load. However, with GPSR, the network shows more stable PDR under medium and high network load. In term of delay OLSR is outperformed by GPSR.
