THE IMPACT OF LOCATION BASED ATTACKS ON GEOGRAPHICAL ROUTING PROTOCOLS
B. Muthusenthil · 2014
Several applications of mobile ad hoc networks sele ct geographical routing especially the Greedy Perimeter Stateless Routing (GPSR) protocol due to its scalab ility, efficiency, and ability to support location based applications. However, there are many security issu es in protecting location information, which can ea sily be abused by attackers. Location based adversarial activities affect the operation and performance of geographical routing protocols. There are only a fe w works on the literature that studied the impact o f location based attacks on geographical routing. Thi s work analyzes the impact of malicious nodes on th e GPSR performance associated with fake location. This proposal identifies a set of possible location ba sed attacks and analyzes the local problems that arise from the location based adversarial activities. Fin ally, it demonstrates the overall impact on the routing perf ormance, by simulating the network in various attac k scenarios. This study illustrates the effect of the adversarial activities with respect to the packet delivery ratio, overhead, average end-to-end delay, routing loops, packet dropping probability, and location er ror rate. The simulation results concluded that the ove rall routing performance degrades, depending on the type and percentage of adversaries.
