چکیده
Cuvinte cheie. Protocoale de rutare, model de mobilitate, reţea ad-hoc fără fir, rată de livrare a pachetelor, controlul suprasarcinii Rezumat. Acest articol analizează performanţele unui protocol de rutare multi-hop utilizat în reţelele VANET (Vehicular Ad-Hoc Wireless Networks)VANRP. Se realizează, de asemenea, o comparaţie între protocolul VANRP şi alte două protocoale utilizate în reţelele ad-hoc urbane ((MURU şi AODV). Rezultatele simulărilor demonstrează că protocolul VANRP este mai performant din punct de vedere al ratei de livrare a pachetelor şi al controlului overhead-ului.

are a subset of MANETs in which vehicles are considered as network clients. These networks have been created to communicate between vehicles and traffic control on the roads. have similar features to MANETs and their main special property is the high-speed node mobility which makes a quick change of the network. The rapid change of network topology is a major challenge in routing. One of the we...

Vehicular Ad hoc Networks (VANETs) are a specific class of Mobile Ad hoc Networks (MANETs). Since vehicles tend to move in a high speed, the network topology is rapidly changed. Thus vehicle’s connectivity problem is one of the interesting issues in VANETs. Ad hoc On-demand Multipath Distance Vector (AOMDV) is an extended version of ad hoc on-demand distance vector (AODV). AOMDV is designed to ...
