Vehicular Ad-hoc NETworks (VANETs) use cars as nodes to create a mobile network, mainly for safety purposes.
IEEE 802.11p is the incumbent WiFi-like solution, based on CSMA/CA: despite effective this solutions cannot completely guarantee reliability.
For this reason alternative paradigms are being explored: MS-Aloha(*) is one of the most promising solutions. It includes several features addressing the main issues in VANETs. MS-Aloha is, in short:
- Completely distributed
- Hidden-Terminal Free
- Scalable and Non-blocking thanks to Smart Slot Re-Use
- Dynamic and Reactive to Mobility
- PHY- and DataLink- compatible with IEEE 802.11p Std
Additional features are currently under development and aimed at solving possible synchronization issues.
MS-ALOHA is developed by the Broadband Wireless Access (BWA) Lab of Istituto Superiore Mario Boella.
(*) The proposed techniques are covered by an European pending patent application No. EP10163964.9 Date of filing: 26/05/2010
