Merging sub-networks in VANETs by using the IEEE 802.11xx protocols.

Abstract

Nowadays most mobile ad-hoc networks are based on the IEEE 802.11 standards for wireless technology under the Wi-Fi brand. The structure of such protocols produces several problems when distinct sub-networks are to be merged. The main troubles that can cause inability to communicate are IP duplication and the existence of sub-networks on different channels. A practical solution to these issues has been fully implemented in a new tool developed to create a vehicular ad-hoc network by using only smartphones. This paper proposes both a simple and deterministic algorithm, and a more complex procedure that considers interferences between wireless channels under a fuzzy logic approach. Both from the performance and security points of view, encouraging results were extracted from the analysis of large scale simulations based on data obtained through executions on smartphones.
