Abstract:

In order to improve the relay delay and successful relay probability performances of high frequency token protocol (HFTP), derived from HFTP token relay protocol,a distributed collisionfree token relay protocol named sub queuedynamic token relay protocol (SQDTRP) is presented, Through the introduction of the communication object column in the relay subqueue, the realtime network status are reserved as much as possible for the dynamic searching of token relay paths. As a result, potential collisions in acknowledgement to SOLICIT-RELAY and the token passing impartiality problems are well corrected by this protocol. Simulations indicate that the token relay delay and token relay success probability of SQDTRP are better than HFTP, which makes it very suit for high frequency (HF) network and other kinds of wireless networks, too.

Key words: media access control, high frequency token protocol, token relay, sub-queue, relay delay, successful relay probability
