Ad hoc network system based on infrared communication

Recently, it becomes popular to use small size computers such as notebook computers or PDAs in the mobile environment. It sometimes happens that several computers meet at the same place such as meeting rooms or conference sites. In such environment, there are demands to make a direct communication among mobile computers. Route maintenance and host enumeration are key requirement for such an ad hoc network. In this paper, we propose a network system based on infrared communication. Our system solves host enumeration as well as route maintenance using diffusing computation. We describe autonomous communication protocol for the ad hoc network and an implementation of mobile system using the protocol
