Abstract:
This paper summarizes the developments of a
genetic-based rate control algorithm. The aspect of rate control
design focused on in this research work is specifically for
implementation on the link/network layers. In this respect, the
underlying concept is to adjust dynamically the transmission rate
subject to variations in the network conditions such that distinct
QoS requirements from individual users are complied with. The
novelty of this work is mainly from two points of views: firstly,
the consideration of near-far effects in the assignation of
transmission power, and secondly, the dynamic allocation of
bandwidth in accordance to the variations in network conditions
which, include but not limited to, traffic characteristics and
network loading. Simulation results show that the proposed rate
control algorithm not only reduces the undesirable outage
probability, but also increase the overall system throughput due
to a reduced number of necessary retransmission.
