English Abstract

Recently, Vehicular Ad-Hoc Networks (VANET) has grabbed the attention of researchers due to the importance of this type of networks in achieving Intelligent Transport Systems (ITS).

VANETs are useful in both safety and non-safety applications where interchanging information between vehicles on the form of vehicle-to-vehicle (V2V) or Interface-to-vehicle (I2V) communication can help in reducing accidents or saving time and effort when searching for the closest fuel station for example.

Since its new birth, the field of VANET has its own problems that need to be addressed by researchers in order for this field to flourish and be commercialized globally.

One of the challenges is the broadcasting management.

The use broadcasting in VANET is important due to the high mobility of vehicles, the distribution of nodes within the network changes very rapidly and unexpectedly that wireless links initialize and break down frequently and unpredictably.

However, broadcasting should be managed and controlled in a way that prevents damaging problems such as broadcast-storm or increasing number of collisions between broadcasts.

The problem that existed in basic flooding technique has been improved using other techniques such as the dynamic broadcasting technique; however, the latter has affected something else, like the delay.

Therefore, this research proposes a new technique that tries to combine the best of both techniques.

The new proposed Hybrid Broadcasting technique works on a way that takes the importance of messages to be broadcasted into consideration and therefore chooses the mechanism on which it relies to broadcast the messages.

The new technique has shown moderate performance between the two techniques due to the effect of using the basic flooding technique as part of it, which degraded the performance of the hybrid technique with regards to number of collisions, or message delivery ratio.

However, in terms of delay, it has shown better performance than the dynamic technique therefore, the new technique has balanced between different metrics such as delay, delivery ratio, message loss, and other metrics in a way that lets the technique adapts in different scenarios easily and dynamically.
