چکیده
Delta compression is the process of comparing two files to produce a set of instructions that will convert one file into the other. Storing or transmitting a delta file rather than the entire new file can offer significant efficiency gains. However, the different aspects of delta compression efficiency, like many problems in computer science, can rest at different ends of a balance. There does not exist a single delta compression algorithm that performs the best in every environment because performance requirements may vary. In order for a user of delta compression to choose the best algorithm for his situation, he must have some understanding of the strengths and weaknesses of the various delta compression algorithms available to him. JDelta, a Java-based delta compression utility, has been designed and implemented to both aid in this understanding, and to provide a framework for the future development of new delta compression techniques.

An Empirical Study of Delta Algorithms
Delta algorithms compress data by encoding one le in terms of another. This type of compression is useful in a number of situations: storing multiple versions of data, distributing updates, storing backups, transmitting video sequences, and others. This paper studies the performance parameters of several delta algorithms, using a benchmark of over 1300 pairs of les taken from two successive rel...

متن کاملEnergy-aware Reprogramming of Sensor Networks Using Incremental Update and Compression
Reprogramming is an important issue in wireless sensor networks. It enables users to extend or correct functionality of a sensor network after deployment at a low cost. In this paper, we investigate the problem of improving energy efficiency and delay of reprogramming by using data compression and incremental updates. We analyze different algorithms for both approaches, as well as their combina...
متن کاملExperimentally Evaluating In-Place Delta Reconstruction
In-place reconstruction of delta compressed data allows information on devices with limited storage capability to be updated efficiently over low-bandwidth channels. Delta compression encodes a version of data compactly as a small set of changes from a previous version. Transmitting updates to data as delta versions saves both time and bandwidth. In-place reconstruction rebuilds the new version...
