Distance-Based Stable Routing Decision Scheme in Urban Vehicular Ad Hoc Networks

Abstract

A number of ad hoc routing protocols of vehicular ad hoc network (VANET) have been proposed and evaluated based on mobile ad hoc network (MANET) routing protocols. Although a large number of routing protocols have been developed in MANET, the VANET has different environments such as highly dynamic topology, frequently disconnected network, hard delay constraints for safety-related application, and various communications environments (e.g., highway or urban traffic scenarios). Therefore, development of a suitable routing protocol that considers these characteristics of VANET should be needed. In this paper we suggest the improved distance-based VANET routing protocol compared with the previous researches on urban traffic environments. We apply approaches to packet-collisions avoidance scheme in the intersection and to stable route decision scheme based on the adaptive waiting time. The performance is then evaluated under simulation which is implemented with the Manhattan urban traffic model. The results show the improved performance as compared with the previous researches.

Smart Road Traffic Accidents Reduction Strategy Based on Intelligent Transportation Systems (TARS)

“…In the end, we concluded that all of the step-by-step work in scientific steps, theories, mathematical calculation and performance results evaluation and discussion were verified by supporting explanations. In Section 5 , we discussed the experimental results and compared the performance of TARS protocol with the other similar studies of routing protocols like DBSR and POVRP [ 37 , 38 ].…”

“…The TARS, DBSR [ 37 ], and POVRP [ 38 ] routing schemes were evaluated using a highway scenario in VANETs’ environment on the basis of the following performance parameters: Message Delivery Ratio (MDR), Message Loss Ratio (MLR), Average Delay, and Basic Safety Message (BSM). All of the above parameters are discussed in detail as follows.…”

PMLC- Predictions of Mobility and Transmission in a Lane-Based Cluster VANET Validated on Machine Learning

“…Even without employing the optimization, the scenario with obstacles produced superior results. This was due to lesser network contention and the fact that RBVT protocols forward data along the roads rather than across the roads [12]. This advancement of automobiles to smart vehicles lays the way for a great potential that leads to a variety of services ranging from traditional road safety to smart communication in smart cities.…”

Compressed fuzzy logic based multi-criteria AODV routing in VANET environment

“…al. [9] suggest distance based routing protocol in urban environment that take into account packet collision avoidance in the intersection and route decision depending on adaptive waiting time.However, it is important to observe that the proposed schemes presented in the related works are mostly focused on only two or three factors in their studies. In this work, an improved AODV routing protocol [10][11][12][13] is proposed considering a new combination of attractive significant factors regard number of relay nodes, distance in related to transmission range, angle of movement, and speed variance as inputs to a compressed fuzzy system to solve impression and conflict between these proposed metrics.…”
