移动低占空比无线传感器网络中低时延的数据持续性提高算法
Low-latency algorithm for improving data persistence in mobile low-duty-cycle wireless sensor network
摘要
Abstract
Mobile low-duty-cycle wireless sensor network (MLDC-WSN) are a kind of new ad hoc networks that are ap-peared in recent years. In MLDC-WSN, the nodes only have limited storage spaces. Moreover, the nodes would move or sleep from time to time. Therefore, these networks have some problems such as connectivity is hard to be maintained and data are hard to be transmitted to their destinations for storage in time. As a result, data persistence (i.e., the probability that all data can be recovered after some nodes die in the networks) is low. A distributed algorithm named LT-MDS for improving data persistence in MLDC-WSN was proposed. The algorithm used a new infectious data dissemination method to transmit the data, which enabled the data to be received by almost all the mobile nodes in a network with low latency and improved the reliability of the network. When a node receives the data, it would use LT (Luby transform) codes to encode and save them. By this way, the nodes with limited storage spaces can save more data information. The-oretical analyses and simulations show that LT-MDS can complete the process of data dissemination and preservation with low latency, and it can achieve high data persistence.关键词
