Abstract :
The IEEE 802.11 standard defines a Request to Send/Clear to Send (RTS/CTS) mechanism to reduce the impact from self-interference such as hidden terminals. However, the usage of RTS/CTS is only based on a pre-defined fixed packet size threshold, focusing only on the cost rather than the presence of interference. This paper presents an RTS on Demand (RoD) mechanism to dynamically utilize the RTS/CTS based on the interference situation (e.g. collision) by monitoring various parameters such as response frame to an unknown station, retransmission attempt, and collision rate monitored at the intended receiver. Numerical analysis of the proposed RoD mechanism compared to the conventional 802.11 RTS/CTS mechanism is provided in the paper.
