Analysis of Effectiveness of ALERT Protocol against Wormhole Attack in MANETs
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 5
Abstract
Routing in MANETs is one of the challenging issues because it dynamically changes their topology over the time and hence requires an efficient routing protocol to communicate among the mobile nodes. There are several routing protocols proposed for MANET environment categorized as non-location based protocols and locationbased protocols. Among all routing protocols the location based routing protocols are preferred in MANETs as they are more efficient in routing compared with the non-location based routing protocols. On the other hand security is also the challenging issue in the MANET due to its feature like open access medium, lack of central monitoring and management etc. and therefore increased the possibility of eavesdropping, spoofing, and denial-of-service attacks. The wormhole attack is one of the stronger active attacks which are difficult to avoid/detect in any network where the two or more attacker nodes tunnel the network traffic information from one location to another in the network. In this paper we focus our study on efficient location based routing protocol ALERT and their effectiveness measure against wormhole attack based on parameters like throughput,end-2-end delay ,packet delivery ratio and normalized routing load. The performance analysis is done for 10,20,30,40 and 50 nodes using the network simulator (NS- 2.35).A comparative study is represented on above parameters for all five scenarios.
