Road Perception Based Geographical Routing Protocol for Vehicular Ad Hoc Networks

Abstract

properly cited.Vehicular ad hoc networks (VANETs) are going to be an emerging multihop communication exploit among vehicles to deliver data packets. The special characteristics of vehicular network make the communication link between vehicles unreliable. To handle high mobility and environmental obstacles, most of geographical routing protocols do not consider stable links during packet transmission which lead to higher delay and packet dropping in network. In this paper, we propose road perception based geographical routing protocol named RPGR for VANET. The proposed routing protocol incorporates relative distance, direction, and midrange forwarder node with traffic density to forward the data toward destination in order to improve geographical forwarding between and at the intersections. Simulation results show that the proposed routing protocol performs better as compared to existing solutions.

Intermittent geocast routing in urban vehicular delay tolerant networks

“…Road perception based geographical routing [12] is a representative geographic information based routing protocol. It incorporates relative distance, moving direction, and intermediate forwarders with traffic density to forward data to the destination.…”

“…Also, VDTNs are an innovative solution that exploits only opportunistic connectivity among vehicles moving in surrounding areas to achieve greedy data forwarding [6] . Routing algorithms for vehicular networks can be divided into two categories: connection-aware routing [7][8][9][10][11] and geographic information routing [12][13][14][15][16][17][18] . The advantages of connection-aware routing are a higher success rate of data dissemination and lower data retransmission times; the disadvantage is that it cannot guarantee the quality of multi-service disseminations.…”

Social-aware routing for cognitive radio–based vehicular ad hoc networks

“…However, routing is a crucial issue that bottlenecks the performance of the entire network and has not been widely studied in CR-VANETs. Different from traditional CR scenarios, existing routing solutions for cognitive radio ad hoc networks (CRAHNs) and VANETs 8,9 cannot apply to CR-VANETs, due to the mobility characteristic of vehicles and the dynamic spectrum nature of the CR environment.…”

Slicing on the Road: Enabling the Automotive Vertical through 5G Network Softwarization

“…The need for a dedicated V2X slice has been early argued in [6], and is currently under debate in 3GPP [4]. Indeed, the unique challenges of the vehicular environment [17] and the peculiarities of V2X services do not easily allow a straightforward mapping into the aforementioned reference slices. The major V2X issues that need to be addressed when designing a network slicing framework supporting the automotive vertical are the following:Localized broadcast communications and edge-dominated access should be considered as crucial slice behaviors to support cooperative driving applications demanding ultra-low latency and ultra-reliable connectivity over the RAN.Besides safety applications, having as ultimate goal autonomous driving, multiple heterogeneous services with diversified requirements should also be simultaneously supported (e.g., high-bandwidth infotainment services and diagnostics services) pushing for strict slice isolation.The high mobility of vehicles makes frequent roaming events calling for multi-operator slice coordination.…”
