Abstract:
Method and system for managing hidden node problem in a communication network. A receiving node in the system, upon receiving a data transmission request from at least one transmitting node, dynamically checks status of the channel between the transmitting node and the receiving node. If the channel is found to be clear for transmission, then the receiving node sends a message that indicates that the channel is clear, to the transmitting node, and the transmitting node starts transmitting the data. Upon receiving a message from the receiving node that the channel is not clear for transmission, then the transmitting node waits for a particular time period and attempts the connection again.
