Abstract

Mobile Adhoc Network is an autonomous network formed by creating nodes and establishing wireless connections ­dynamically,­so­that­messages­in­packets­can­be­sent­from­a­sender­to­receiver.­The­unique­architecture­of­MANET­offers several advantages and security challenges as passive and active attacks on the network. We discuss elaborately about the security attacks and two more popular security techniques, Intrusion Detection System (IDS) and Watchdog and Path rater (WPR). The two techniques are evaluated using two measures, viz., Availability Factor (AF) and Integrity Factor (IF). We­present­our­results­and­our­insights­on­suitability­of­a­particular­technique­to­a­specific­networking­application.­Our research is on-going and we indicate the extension possibilities that we are working upon.
