Guest editorial special section on industrial wireless sensor networks

Abstract

The Special Section of the IEEE Transactions on Industrial Informatics contains information on industrial wireless sensor networks. Routing algorithms remain an active topic for research, especially aimed at conserving energy consumption within the resource constrained environment of a typical sensor node, thus extending the lifetime of a sensor node. In one paper, authors describe the real-time implementation of a Harmony Search Algorithm (HSA)-based clustering protocol for energy efficient WSNs. In another paper, the authors address the task of mixed sound verification in WSN-based home environments. Another paper introduces a novel technique which measures and models the relative clock drift between neighbor motes, thereby reducing the effective drift rate. In another paper, the authors address a vital issue of IWSAN communication, i.e., transmission bandwidth priority of critical traffic over non critical traffic.
