ABSTRACT:
A method and apparatus for dynamically determining the persistence value P at a node in a P-persistent CSMA wireless network by determining the number of nodes to which the given node has an established link and which have transmitted within a preceding period of time is provided. The preceding period of time is between 5-60 seconds, preferably approximately 10 seconds. The value of P is set to a value between 1/(0.5N+1) and 1/(2N+1), preferably approximately 1/(N+1).
