Reducing link quality impact to encrypted packets by compressing the transmitted data

Abstract

The encrypted traffics are sensitive to losses, while wireless link in prone to error. Although solutions have been proposed in each TCP/IP stack layer, error or losses is always exist. In order to reduce losses of part(s) of encrypted data, bytes or packets should be as many as possible received by the receiver. This paper examines data compression impact in reducing losses of encrypted data. NS-2 simulator is employed to evaluate the study by using the 802.11 radio link. Simulations show that the 3DES decryption rate increases when compression applied. Packet losses can be reduced about 0.32% and 0.54% for TCP and UDP subsequently. The successful encrypted data rises in average 0.3% and 1.3% for both TCP and UDP.
