Packet conflicts in an asynchronous distributed
CDMA packet radio network is a main
cause of throughput inefficiency and network
instability. To reduce the packet conflicts due to
random packet initiations in the network an alternative
collision-avoiding CDMA protocol, the
receiver-based (R) spreading code sensing protocol,
is proposed and its performance is numerically
analysed. The results reveal that, by using
the code-sensing technique in the conventional
receiver-based spreading code protocol, the
throughput-delay performance and the stability of
the network can be dramatically improved. The
results are also compared with those of other
CDMA spreading code protocols without code
sensing. A two-dimensional time-continuous
Markov chain model for the R code sensing protocol
is developed to evaluate its steady-state performance
