Geographic Routing in Clustered Multi-layer Vehicular Ad Hoc Networks for Load Balancing Purposes
نویسنده
چکیده
To improve the quality of wireless communication and extend the range of applications in Vehicular Ad Hoc Network (VANET), a clustered multi-layer hybrid network structure is proposed by the combination of Wireless Mesh Network (WMN) and Ad Hoc Network. Making use of location information, congestion monitoring and routing switch, we design a geographic routing in VANET for load balancing purposes. The hidden terminal problem has been solved by transmitting data in the forwarding node set. An opportunistic routing algorithm is applied when the network connectivity is poor. Based on the routing switch mechanism for load balancing, unicast and multicast can be achieved to ensure the Quality of Service (QoS) under various network connectivity and load scenarios. Simulation results show that the proposed algorithm can reduce the transmission latency and network packet loss rate, and therefore is more suitable for hybrid VANET architecture.
