Toward next-generation Internet of Things: guest editorial

Abstract

The Internet of Things (IoT) is envisioned as a network of billions or trillions of machines communicating with one another and rapidly gains global attention from academia, industry, and government. IoT is recognized as one of the most important areas of the future Internet; enabling ubiquitous computing among global networkedmachines and physical objects. Equipped things with auto identification devices such RFID tags, sensors, and machine-to-machine (M2M) devices, IoT are applicable in a wide variety of areas such as smart grid, e-health, intelligent transportation, and logistics. This special issue in telecommunication systems aims to present the latest advances of the fundamental technologies and market trends that will impact the design and standardization of IoT by bringing together academic and industrial researchers to identify and discuss technical challenges related to IoT. In response to the call for papers, we were pleased to see many submissions from many countries and areas all over the world, which was far more than we expected. In this section, we have selected the following outstanding articles that reflect the recent research advance. In the article “A Survey on Position-based Routing for Vehicular Ad hoc Networks”, J. Liu et al. outlines the background and the latest development in VANETs and surveyed the state-of-the-art routing protocols previously used in VANETs. Then, the authors present the pros and cons for each routing protocol, and make a detailed comparison. The open issues, challenges and future research directions are
