Description

Mobile Ad Hoc Networks and Applications are formed by wireless hosts which may be mobile Without (necessarily) using a pre-existing infrastructure. Routes between nodes may potentially contain multiple hops. Due to dynamic changes in topology, there is an issue in connectivity, traffic, reliability. Hybrid protocols are used for switching protocols from one network to another depending on the network conditions, but it does not suitable for all network conditions depends on time. So we propose the concept declarative adaptive wireless networking which utilizes the switching protocols from one to another depending on policy declaration, and perform inter protocol forwarding techniques. To ensure fair and secure communication in Mobile Ad hoc Networks (MANETs), the applications running in these networks must be regulated by proper communication policies. However, enforcing policies in MANETs is challenging because they lack the infrastructure and trusted entities encountered in traditional distributed systems. This paper presents the design and implementation of a policy enforcing mechanism based on Satem, a kernel-level trusted execution monitor built on top of the Trusted Platform Module. Under this mechanism, each application or protocol has an associated policy. Two instances of an application running on different nodes may engage in communication only if these nodes enforce the same set of policies for both the application and the underlying protocols used by the application. In this way, nodes can form trusted application centric networks.
