Connection-oriented routing in ad hoc networks based on dynamic group infrastructure
Yu-Liang Chang, Ching‐Chi Hsu · 2002
An ad hoc network is formed by a group of mobile hosts communicating over wireless channels. Such a network operates without any fixed network interaction and centralized administration. For the network environment is highly dynamic, the established routing paths are so fragile to maintain stable communication, especially the connection-oriented communications are quite difficult to be maintained. In our approach, the network infrastructure is initially constructed by several communication groups, which are called the dynamic group infrastructure. This paper proposes the group-level connection maintenance based on the dynamic group infrastructure to implement connection-oriented routing. Our approach enhances the routing robustness of connection-oriented communications. The simulation results show that this routing approach under such a construction outperforms the previous works in message complexity for connection-oriented communications.
