Thesis on vanet

Due to the separation between the control and data planes in VANET, network intelligence can be logically centralized and the underlying network infrastructure can be decoupled from the applications. The centralized control of SDN brings an immense number of advantages, but it also can become a single point of failure of the network.

The figure 1.2 [24] indicates the all components and fields of VANET [24].

VANET manages a network within which vehicles are act nodes and applied as mobile nodes to construct a robust infrastructure-less ad-hoc network. In Figure 1 illustrates the basic components of VANET architecture. It builds the network among Inter-Vehicle, Vehicle-to-Roadside and Inter-Roadside communicating networks [4].

This diploma thesis designs and tests a DDoS detection algorithm for SDN-based VANET networks. The test scenarios include launching normal and DDoS attack traffic with spoofed source IP addresses. Based on traffic features, entropy is used to measure the degree of randomness of occurrence of destination IP address of the packets.
