چکیده
The growing demand for mobility has increased the need to develop more eecient, reliable and cost eeec-tive services for data transmission over the air interface. The air interface, as compared to the wired domain , is characterized by a high bit-error-rate, limited bandwidth, and intermittent connectivity. In addition , power in the hand-held devices and laptops is limited by the battery technology. In this paper, we present AFEC, an Adaptive Forward Error-Correction scheme, which makes eeective use of the air interface by minimizing the number of data bits transmitted to convey message packets in a real time stream over an air interface. Through simulations , we show that AFEC outperforms the traditional single forward-error-correction scheme.

Merging the adaptive networks with the free space optical (FSO) communication technology is a very interesting field of research because by adding the benefits of this technology, the adaptive networks become more efficient, cheap and secure. This is due to the fact that FSO communication uses unregistered visible light bandwidth instead of the overused radio spectrum. However, in spite of all ...
