The collected data often needs to be compressed before being transmitted to the central node or processing unit to save energy and bandwidth. Vector quantization (VQ) is a widely used technique for data compression, which maps a high-dimensional vector to a low-dimensional codebook. However, traditional VQ algorithms require a centralized architecture that may not be feasible in resource-constrained sensor networks. Distributed Vector Quantization (DVQ) is a technique that allows VQ to be performed in a distributed manner, with each sensor node performing its own compression and transmission of data. DVQ has been widely studied in sensor networks, and this research proposal aims to investigate the performance of DVQ in different scenarios and to develop efficient algorithms for DVQ.Objectives: 1. To study the existing DVQ algorithms and their performances in different scenarios2. To analyze the impact of the number of clusters, codebook size, and quantization error on DVQ performance3. To develop new algorithms that can improve the efficiency and accuracy of DVQ in sensor networks4. To evaluate the proposed algorithms using simulation experiments and real-world data setsMethodology:In this study, we will start by reviewing the literature on DVQ algorithms and their performance evaluation. We will then implement existing algorithms using simulation tools such as MATLAB or OMNeT++ to evaluate their performance in different scenarios. We will vary ...
