Abstract: |
In vehicular ad hoc networks (VANETs), routing schemes play a vital role in data dissemination. VANET is a subclass of the so-called Mobile Ad Hoc Network (MANET) and has no fixed infrastructure and is consisted of vehicles instead of mobile nodes. Routing of data in a vehicular ad hoc network is a challenging task due to the high dynamics, unstable connection environments and transfer direction limit (real road planning) of such a network. However, it has been discussed that radio obstacles [1], as they are found in urban areas, have a significant negative impact on the performance of location based routing. Thus, how to design a suitable routing protocol for VANETs is an important issue. As routing protocol in a accuracy and immediacy manner is critical for Inter-Vehicle Communication (IVC) applications, in the paper we introduce a location based routing algorithm namely geographic routing, which significantly reduces the average end-to-end delay, packet dropping probability, and the routing overhead in the network compared to epidemic routing. A 2×2 km grid map has been utilized to assess the performance of our proposed routing scheme.
