Advanced secure routing in ad hoc mobile networks

A group of wireless mobile hosts making a temporary network without conventional infrastructure or central supervision is the ad hoc network. The main challenges exists in secure broadcast communication is enabling the receivers to verify that the data received originates from an authorized source and no change or modification made on it in the communication. In the case of untrusted receivers and unreliable communication, this secure routing is more complicated. This paper provides a secure routing in ad hoc mobile network by detecting and avoiding un trusted hosts in the routes using the FACES(Friend Based Ad Hoc routing Using Challenges to Establish Security in MANETs Systems) protocol. This paper used an existing protocol such as TESLA (Timed Efficient Stream Loss Tolerant Authentication) in routing to show the actual standing of the FACES algorithm.
