ENSURING THE NODE AUTOCONFIGURATION AND NODE PREVENTION FROM INTRUDERS USING SFAP

In ad hoc networks the address assignment is a key challenge due to the lack of infrastructure. An ad hoc network creates frequent network partitions caused by mobility of nodes, fading channels and the nodes joining and leaving the network. These network partition associates the various address collisions. The lack of centralized administration make these network attractive to several distributed applications such as sensing and disaster recovering, So it needs an addressing protocol that configures the mobile ad hoc nodes and avoids the unauthorized access to the networks. This paper presents a Secure-Filter addressing protocol (SFAP) autoconfigures the mobile ad hoc nodes based on a distributed database stored in filters. SFAP resolves address collisions of network partitions by exchanging the hash of the filter among neighbors. Secure-Filter addressing protocols with partition detection identify the partition and advertise periodically about the different set of nodes.SFAP implements the security by filtering the unauthorized access using the Dynamic Hole Detection and healing method. The SFAP is to achieve the robust node autoconfiguration that addresses the network partitions to resolve all the address collisions, controls the message losses and ensures the DHEAL security by preventing the transmission routes between the ad hoc nodes.
