摘要:Ad Hoc networks are a set of wireless mobile communication nodes (stations, users) that exchange information between different nodes in a dynamic environment. The mobile infrastructure help to form the dynamic network structure. Nodes communicate and send information between each other and with the centralized access points without interference. Each node acts both as a router to information or as an end user node that receive the sent information. Information dissemination between different nodes may face lake of security due to accidental or unauthorized message forward to illegal third party. This paper proposes a policy based approach for information transfer over Mobile ad hoc network (MANET) using messages privacy control where the creator of the message determines the nodes that should receive the message and deny sending the message to other nodes. Each message is sent in combination with a policy which controls its sending behavior at the receiver side. The policy is applied at the application level. A simulation of the proposed approach has been programmed to perform experimental case studies. The results have proven the efficiency of the proposed approach in securing the privacy of information transfer.
