A dynamic network gateway selection scheme based on autonomous clustering for heterogeneous mobile ad hoc network environment

Many types of mobile ad hoc networks such as vehicular ad hoc networks that consist of vehicles and pedestrian mobile ad hoc networks that consist of people have been proposed for various application. In heterogeneous mobile ad hoc network environment that consists of many types of mobile ad hoc networks, each network uses a routing protocol suitable for the characteristics such as topology change frequency and data traffic. In such a network environment, nodes between different networks cannot communicate with each other because each network uses a different routing protocol. Therefore, the network gateway nodes between different networks are required. However, in mobile ad hoc network environment, it is difficult to fix the network gateway nodes in the network because nodes are always moving. In this paper, we propose a new scheme based on the autonomous clustering to dynamically select the network gateway nodes according to the network topology change in heterogeneous mobile ad hoc network environment and confirm the performance of the proposed scheme through simulation experiments.
