Vehicle ad-hoc network (VANET) with large scale and node distribution and the characteristics of mobility

networking of VANET technology has become a research focus in the field.For urban traffic environment

this paper proposes a clustering structure of VANET network scheme

using a bus as a cluster head

dynamic cluster head election

dynamic management of cluster members

In terms of network connectivity

this paper discusses the use of roadside parked vehicle cache forwarding strategy

Theoretic analysis and simulation results show that proposed scheme can effectively extend the time of communication

improve the transmission efficiency.
