The low rate of transmission to persons with casual contact suggests that aerosol transmission via the respiratory tract is not efficient, if it occurs at all.

Our research has showed that SPIHT performs better than JPEG while the underwater images are coded in low bit rate. SPIHT also has a good progressive transmission characteristic.

In this scheme, an MS USES a low transmission rate for data transfer when MS is within high interference region to avoid wasting bandwidth by transmitting data in the condition with high interference.
