Utilizing Object Compression for Better J2ME Remote Method Invocation in 2.5G Networks

Jalal Kawash, Ahmad El Halabi, Ghassan Samara


This paper introduces two new Java 2 Platform Micro Edition (J2ME) Remote Method Invocation (RMI) packages. These packages make use of serialized object compression and encryption in order to respectively minimize the transmission time and to establish secure channels. The currently used J2ME RMI package does not provide either of these features. Our packages substantially outperform the existing Java package in the total time needed to compress, transmit, and decompress the object for General Packet Radio Service (GPRS) networks, often called 2.5G networks, even under adverse 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 packages.
