Geocast routing: Recent advances and future challenges in vehicular adhoc networks

Recently, geocast routing (GR) has been extensively investigated for reliable and efficient dissemination of information due to increasing number of intelligent transport system (ITS) applications favoring geocasting. In this paper, a qualitative survey of recent protocols of GR and some precise future research issues have been provided.

A functional and qualitative description of each considered protocols have been presented. All the considered protocols have been comparatively characterized. This comparative study leads us towards some future research challenges in GR.
