Quantifying the Negative Impact of Mobility and Location Service Inaccuracy on Geo-Routing in Urban Vehicular Environments

چکیده
Vehicular routing has been an extremely active research field in recent years with geo-routing protocols typically favoured over conventional topology based routing protocols due to their advantages in terms of scalability and lower overhead. Before a geo-routing protocol can transmit a packet, it must be aware of the position of the target node and is reliant upon a location service to supply this information. Therefore the correct and efficient operation of the routing protocol is entirely dependant on the accuracy of this information. In this paper, a simulation based analysis is conducted to determine the tolerance of a geo-routing protocol to position inaccuracy as reported by a location service. As the inherent mobility of a vehicular network may also have a negative impact on protocol performance, we also evaluate characteristics such as vehicular density, transmission range and query range.
