Efficient use of java MIDP record management system in wireless devices

We present an approach that can promote the efficient use of the Java Mobile Information Device Profile (MIDP) record management system (RMS) in wireless devices such that faster record retrieval using a smaller memory is achieved, which makes the device consume less battery power. The comparable program segments, which show how to use Java MIDP RMS efficiently with or without a record-enumeration interface, are presented and analyzed. The proposed approach supports faster access of record traversal, which shows O(log n) time to retrieve any record in an MIDP RMS file, while the record retrieval in the current Java MIDP RMS takes O(n) time. In addition, the proposed approach uses less RMS storage than the method using the record-enumeration interface does
