Hidden Node Problem in Remote Ad-Hoc Networks

The hidden node issue is a well-known phenomenon in IEEE 802.11 wireless networks. This research work show that the well-known ready-to-send / clear-to-send (RTS / CTS) approach, which is used to solve the hidden node problem, is ineffective in this case. We conducted real-world network experiments to examine the impact of hidden nodes in infrastructure as well as ad hoc multi-hop networks. Transmission and Carrier sensing channel models are proposed in this investigation. As a solution to the hidden node problem, this research work will also study the RTS / CTS mode. The proposed model utilizes 2 Mbps or 11 Mbps to transmit RTS / CTS not only solve the problem but also degrades the performance by introducing additional over ad network. This paper attempts to identify the basic conditions that lead to the hidden node. In particular, the proposed research work shows that the occurrence of hidden node is primarily due to the limitations of the 802.11 protocol. Based on the insight gained from the study, this research work is designing a hidden-node-free model that eliminates the hidden node entirely.
