Mobile data collection of wireless sensor networks with speed control

Abstract

Abstract Reducing delay has an important position in the data collection of wireless sensor networks. Current mobile sink may use single antenna to collect data, but necessarily use two antennas if the data amount is large. The purpose of the research is to reduce the delay of data collection. Unlike many traditional methods, our approach has not parking positions of mobile sink in the process of data collection. We propose an algorithm based on speed control of mobile sink that reduces the delay of data collection. The algorithm combines speed control and two antennas of mobile sink. Our algorithm ensures reducing the delay of data collection.
