Abstract:
|
In this paper, an inhibit sense multiple access–direct sequence/code division multiple access (ISMA-DS/CDMA)
medium access control protocol for a packet transmission mobile
radio network is presented. The main feature of this protocol
is its ability to retain the inherent flexibility of random access
protocols while at the same time reducing to some extent the
randomness in the access in order to increase the system capacity.
In this framework, the protocol is presented together with some
adaptive mechanisms that improve the protocol performance by
means of regulating the access and varying the transmission bit
rate according to the channel load that is broadcast by the base
station. As a result, an adaptive bit rate algorithm is presented
that reaches a throughput value close to the theoretical maximum. |
