High Performance Peer-to-peer Data Dissemination for Decentralized Wireless Sensor Networks Firmware Updating

Abstract

Data dissemination is an important feature to enable reconfigurations and firmware updates in wireless sensor networks. Typically, data disseminations in modern wireless sensor networks are based on multicast-based algorithms which may not be the most efficient ways because they do not guarantee packet delivery. In this paper, we present a reliable data dissemination algorithm for distributed wireless sensor networks. It derives some features from BitTorrent such as segmented file transfer, choking, and optimistic unchoking to improve performance. The evaluation result shows that our algorithm performs better than multicast-based algorithms in term of download speed up to 58.97% and energy efficiency up to 79.39%.
