Assisting V2V failure recovery using Device-to-Device Communications
This paper aims to propose a new solution for failure recovery (dead-ends) in
Vehicle to Vehicle (V2V) communications through LTE-assisted Device-to-Device
communications (D2D). Based on the enhanced networking capabilities offered by
Intelligent Transportation Systems (ITS) architecture, our solution can
efficiently assist V2V communications in failure recovery situations. We also
derive an analytical model to evaluate generic V2V routing recovery failures.
Moreover, the proposed hybrid model is simulated and compared to the generic
model under different constrains of worst and best cases of D2D discovery and
communication. According to our comparison and simulation results, the hybrid
model decreases the delay for alarm message propagation to the destination
(typically the Traffic Control Center TCC) through the Road Side Unit (RSU)Comment: 3 page
A Hybrid Model to Extend Vehicular Intercommunication V2V through D2D Architecture
In the recent years, many solutions for Vehicle to Vehicle (V2V)
communication were proposed to overcome failure problems (also known as dead
ends). This paper proposes a novel framework for V2V failure recovery using
Device-to-Device (D2D) communications. Based on the unified Intelligent
Transportation Systems (ITS) architecture, LTE-based D2D mechanisms can improve
V2V dead ends failure recovery delays. This new paradigm of hybrid V2V-D2D
communications overcomes the limitations of traditional V2V routing techniques.
According to NS2 simulation results, the proposed hybrid model decreases the
end to end delay (E2E) of messages delivery. A complete comparison of different
D2D use cases (best & worst scenarios) is presented to show the enhancements
brought by our solution compared to traditional V2V techniques.Comment: 6 page
