Recently, the rapid development in computer network fields especially in mobile and wireless technologies has attracted much attention. With the maturity of these technologies, new applications are introduced such as mobile ad hoc network, wireless sensor network and to our concern; Network Mobility (NEMO). NEMO is an extension protocol to mobile ipv6 in providing seamless connection to every node in the network. By using the mobile router, mobility support is provided to each fix or mobile node in the network even though there is a change in the network topology in a sense that the mobile router changes the point of attachment to the network. NEMO also supports a nested environment where a mobile network can attach to another mobile network by encapsulation and tunneling techniques. However, the expandability of NEMO raises the problems of route optimization and packet encapsulation overhead. In this paper, we will discuss and provide route optimization by adapting Ad-hoc On Demand (AODV) routing protocol into NEMO environment.
