LIGHTWEIGHT VIGILANT PROCEDURE TO IMPLEMENT SECURITY MEASURES IN HIGHLY ROVING MILITARY OPERATIONS

The performance of Mobile Ad hoc Network (MANET) becomes questionable in highly roving and mission critical application like military operation. Security measures like encryption, authentication, digital signature has been proposed for MANET. However all those mechanisms need some kind of static infrastructure and it is extremely difficult to implement such an infrastructure throughout the military mission. Therefore in this work, various zones in military operation is identified and Zone A is responsible for implementing robust security measures, Zone B and Zone C are identified to be at highly hostile and time critical environment. Therefore usage of highly complex security procedures at zone B & C may delay the operation to the extent of failure of the mission. Hence in this study, a lightweight vigilant procedure that suits the circumstances of Zone B & C is proposed, it has the capability of detecting the malicious entrant in the routing path. Moreover, it works either independently or dependently with the routing protocols like AODV based on the need. The proposed method has been compared with various successful security measures in Ad-hoc network and the results shows that the proposed method is very useful in adapting to the conditions of zone B & C.
