A cluster based reliable group communication for secure manet

Abstract

A Mobile Ad hoc Network MANET is a network consisting of a newlinecollection of nodes capable of communicating with each other without help newlinefrom any network infrastructure The nature of MANET poses a great newlinechallenge to system security designers due to its wireless nature lack of newlineonline Central Authority or Trusted Third Party limited power vulnerability newlineto Denial of Service attacks and more probabilities for trusted nodes being newlinecompromised and then being used by adversary to launch attacks on the newlinenetwork In other words MANETs are highly prone to both internal and newlineexternal attacks Authentication confidentiality integrity nonrepudiation newlineand availability are five important security services that address the above newlinechallenges newline newline
