Abstract

The 802.11 DCF was designed for the single-hop wireless LAN scenario, where one central control system such as AP controls many nodes and mitigated the hidden terminal problem by exchanging the RTS/CTS message. However, in Mobile Ad Hoc Network (MANET), RTS/CTS exchange mechanism is not sufficient to solve hidden terminal problem and also this mechanism reserved a space more than needs so that spatial reuse is reduced. In this Paper, we proposed new Distributed MAC protocol to mitigate the hidden terminal problem and to increase the spatial reuse. we classify the neighbor nodes into two states – free state and constraint state – based on the interference tolerance of a receiving node.
