A Literature Survey on Secure Gateway Discovery in MANET

Abstract: Mobile Adhoc network (MANET) is a collection of mobile node that can communicate with each other via radio or infra without any fixed infrastructure. MANET is a wireless network so to connect with internet any interface is needed that is called gateway which provide route to the internet. Due to dynamic topology packets are loss which degrade network operation. So, to achieved high throughput security scheme are applied on internet gateway which helps to out from adversarial environment. There is some security goal are discussed (confidentiality, integrity, authentication and non-repudiation) which enhanced adhoc network operation. In this paper, we survey on the gateway discovery scheme with security and without security based on various performance parameter like packet delivery ratio, end to end delay, routing overhead and throughput and then conclude which one is better. Keywords: Mobile adhoc network(MANET) ; Secure and Non- secure Gateway discovery ; Attacks; Security goal ; Rabin signature scheme.
