Abstract
In order to solve the problem of broadcast storm and broadcast unreliability in Vehicular Ad Hoc Networks (VANET) on highways, an improved algorithm based on Speed Adaptive Probabilistic Flooding (SAPF) [1], which is referred to as Average Speed Based Broadcast (ASBB), is proposed. Since the average speed of vehicles in the vicinity reflects the network congestion around the current node more accurately, ASBB dynamically calculates the forwarding probability according to the average speed of the current node and the corresponding neighbor nodes. To obtain the speed of neighbor nodes, each node encapsulates its speed into the header of packets it transmits, instead of employing new types of packet for exchanging speed. This approach alleviates the network load and reduces the complexity of implementation. Meanwhile, only the nodes located behind the current node may participate in the forwarding of the broadcast packet, which reduces the number of nodes participating in the forwarding and further mitigates the broadcast storm and improves the broadcast reliability. The simulation results show that ASBB performs well in terms of suppressing broadcast storms, increasing the reachability and reducing the end-to-end delay.
