Investigation of Link Layer in Inter-Vehicle Wireless Communication
AbstractSafety message transmission is the key task of inter-vehicle communication. It is affected by obstacles on the road, and in many cases these obstacles are non-equipped vehicles. This paper presents link layer investigation between two cars. Lost packet distribution is given for LOS and NLOS cases and approximation polynomials are found using mean square criterion. Lost packets are building groups and trend of this grouping is also approximated using polynomials. As an outcome communication channel model is presented which can be used for realistic modelling tasks. Ill. 5, bibl. 7, tabl. 1 (in English; abstracts in English and Lithuanian).
