MORE EFFICIENT JAVA RMI FOR GPRS DEVICES

This paper introduces a new J2ME RMI package, which makes use of object compression in order to minimize the transmission time. The package also makes use of object encryption for secure channels. The currently used RMI package for wireless devices does not provide either of these features. Our package substantially outperforms the existing Java package in the total time needed to compress, transmit, and decompress the object for GPRS networks, even under adversary conditions. The results show that the extra time incurred to compress and decompress serialized objects is small compared to the time required to transmit the object without compression in GPRS networks. Existing RMI code for J2ME can be obliviously used with our new package.
