Reliable Forwarding Strategy in Vehicular Networks Using NDN

Abstract

Vehicular networks are expected to support numerous applications, such as emergency announcement, traffic congestions for travelers and intelligent transportation systems. But due to high vehicular mobility, vehicular networks suffer long transmission delay and intermittent end-to- end connectivity. The paper proposes a reliable forwarding strategy aiming to establish reliable end-to-end connection taking vehicular velocity differences into account. The scheme can also replace the use of timers so as to reduce network latency. The paper uses an analytical model to study the impact from forwarding distance of the reliable path under different circumstances such as vehicular density, vehicular transmission range and velocity variance.
