Title
An Efficient Gateway Discovery Algorithm with Delay Guarantee for VANET-3G Heterogeneous Networks
Abstract
The integration of VANETs and 3G networks promises a good perspective of easily exchanging information among VANETs, 3G Networks and Internet. However, as a 3G base station's capacity is limited, too many requests from vehicles with 3G UTRAN interfaces, may bring with them long communication delay and lots of collisions. In this paper, we propose a novel gateway discovery algorithm for VANETs, providing an efficient and adaptive location-aided and prompt gateway discovery mechanism (LAPGD). Here, all vehicles go across selected mobile gateways to access 3G networks instead of direct connection. The algorithm aims to ensure every vehicle capable of finding its optimal gateway, to minimize the total number of gateways selected in VANETs, and to guarantee the average delay of packets within an allowable range. We implement this algorithm and prove its correction. Simulation results show the performance of the algorithm is affected by such parameters as the maximum coverage of a gateway, the number of gateways, as well as the requesting delay. The results indicate the algorithm is significant in gateway selection
