Abstract

An ad-hoc network, which does not require a base station such as an access point, has a hidden node problem because nodes communicating in the same time cannot know each other's communication status. In other hand, in the wireless infrastructure network the access point manages the communication with the node using RTS (Request to Send) and CTS (Clear to Send). However, in the broadcasting, we cannot use RTS/CTS method because the number of target nodes is not 1 but more than 2. In this paper, we propose a broadcasting method based on RTS/CTS to avoid this problem. Sender node selects the target node. And they communicate with each other. Neighbouring nodes can listen to these packets. Then sender node can broadcast its information to multi nodes. We use wireless nodes specified by IEEE 802.15.4 which is the physical layer's specification. And our experiment results show the effective transmission.
