PhD Project Topics in Vehicular Ad Hoc Networks

Vehicular Ad Hoc Networks (VANets) is becoming an emerging trend to meet the various demands in real time application. In these networks, vehicles communicate with each other and possibly with a roadside infrastructure to provide a long list of applications varying from transit safety to drive assistance and Internet access Most of the concerns of interest to mobile ad hoc networks (MANETs) are of interest in VANETs, but the details differ. Rather than moving at random, vehicles tend to move in an organized fashion. The interactions with roadside equipment can likewise be characterized fairly accurately. Most vehicles are restricted in their range of motion. Such a network might poses safety concerns for example, one cannot safely type an email while driving. GPS and navigation systems might benefit, as they could be integrated with traffic reports to provide the fastest route to work. It was also promoted for free, VoIP services such as Google Talk or Skype between employees, lowering telecommunications costs. The future features of vehicular adhoc networks are taken into consideration by S-LOGIX with an angle to emphasize on emerging domains for real time applications.
Extension to the existing protocols or modeling a new Protocol in NS2 for VANET can be done in the following aspects. The protocols are developed as C++ files, and the dependent files are modified in the NS-allinone package. The directory structure of the newly added files is mentioned in Makefile. Then NS is rebuilt using Linux utility tool make. Simulation is carried out by mentioning the newly developed protocol in the TCL configuration file. Implementation aspects of NS2 for the VANET protocols are as follows.
There are numerous metrics depends on the proposed approach and the network scenarios apart from the above. AWK script for these metrics can be applied to process the trace file that consists of the information such as event time, event type, node ID, packet sequence number, type and size of the packet, the layer at which the event occurs, the reason for packet drop, and TTL. The results from the execution of AWK script can be plotted as Xgraph in NS2 for the purpose of self or comparative protocol analysis.
