CaCa: Chinese Remainder Theorem Based Algorithm for Data Aggregation in Internet of Things on Ships
Feng Xie · Applied Mechanics and Materials · 2014
Internet of Things can be used as a key technology or architecture on marine ships for remote equipment maintenance. Data aggregation in Internet of Things is a critical issue for the efficiency of sensing data collection. The volume of sensing data is huge because the number of equipments is large. It is thus mandatory to decrease the communication overhead in data aggregation. In this paper, we propose a Chinese Remainder Theorem based coding algorithm for data aggregation, called CaCa. The communication efficiency is improved by CaCa (at least 90% very likely), which is justified extensively by formal analysis and rigorous proof.
