We Can Deliver Messages to Far Vehicles

Abstract

Vehicular ad hoc networks (VANETs) enable vehicles to communicate with each other but require efficient and robust routing protocols for their success. In this paper, we exploit the infrastructure of roadside units (RSUs) to efficiently and reliably route packets in VANETs. Our system operates by using vehicles to carry and forward messages from a source vehicle to a nearby RSU and, if needed, route these messages through the RSU network and, finally send them from an RSU to the destination vehicle. Our system is mostly critical for users who are far apart and want to communicate using their vehicles' onboard units. Many recent paradigms, like social networks, will greatly benefit from a system like ours to enable users on the road to exchange different types of data. We evaluate the performance of our system using the ns2 simulation platform and compare our scheme to existing solutions. The results prove the feasibility and efficiency of our scheme.Index Terms-Carry and forward, geographic forwarding, intervehicle communication, roadside units (RSUs), routing, vehicular ad hoc networks (VANETs).

Performance Evaluation of Network Aggregation Techniques in VANET

“…Routing is very important issue in VANET, because we have to establish the network between moving vehicles [10]. The network must have maximum system capacity, less computational complexity and also able to give high throughput.…”

DTN Protocols for Vehicular Networks: An Application Oriented Overview

“…Most of the protocols covered in this survey simply ignore the impact of reliability. Those that consider and use it are: DTFR [65], D-Greedy and D-MinCost [70], CAN DELIVER [72] and MSDP [60].…”

“…However, their implementation is complicated and depends on many user-defined parameters, which may lead to incompatibilities. , the protocol presented in [71], and CAN DELIVER [72].…”

“…The cost of coding depends on the amount of extra fragments sent. Fragmentation and coding only appear in two of the protocols we have reviewed, which are CAN DELIVER [72] and MSDP [60].…”

Formal Verification of Safety Message Dissemination Protocol for Vanets

“…Current research shows that RSUs are emerging as a viable economic option for message dissemination. RSUs can be efficiently and reliably used to route packets in VANET, especially when users who are far apart want to communicate (Mershad et al, 2012). Sou and Tonguz (2011) have analyzed the connectivity and routing performance when RSUs are deployed for broadcast based safety applications.…”
