Scalable ALARM: Anonymous Location Aided Routing in Hostile MANETs

Hostile MANETs are significant because of their applications inmilitary and law enforcement area where the identity of thenodes cannot be revealed since there is a risk of tracing andlocating them with their identities, which makes the networkvulnerable to attacks. Therefore communication between nodesshould be performed with the help of location information whichmitigates the risk of exposure. Security and privacy in locationbased communication within suspicious MANETs can beenforced using the group signature scheme along with theALARM protocol which can provide authentication of nodes,data integrity and intractability but lacks scalability due toexcessive broadcasting of link state information. This studyproposes, HOLSR addresses the scalability problem by providinga resilient approach to enhance the scalability feature of ALARMprotocol.
