Data-centric communication strategy for wireless sensor networks

摘要

Recently, the popularity of the internet of things technology has highlighted the importance of performance for gathering data over multi-hop wireless sensor nodes. Data obtained from the sensor nodes is used by individual as well as multiple users. Therefore, a data-centric communication strategy is ideal for efficient data gathering and delivery. This paper proposes the implementation of a new data-centric communication strategy based on the named data network (NDN) to wireless sensor network (WSN) for achieving efficient communication performance. We discuss the modification of the NDN, which is originally developed for a wired network, for achieving better communication performance even in wireless communication networks. Specifically, we discuss the methods for constructing the reverse path of the required contents and for selecting the adequate next hop relay node of the forwarding interest. We propose new methods considering the broadcast nature of the wireless channels. Using computer simulations, we confirm that our proposed methods reduce the redundant transmissions by selecting a proper route based on network conditions.
