The Internet of Things (IoT) enables several heterogeneous devices, sensors, wearables, appliances and many other objects to inter-communicate and provide support for heterogeneous services. An IoT network needs to enable exchange diverse data types including multimedia and sensor data and be capable of handling a large number of IoT objects offering services at high quality levels. This paper proposes...
Despite many Internet of Things (IoT) Infrastructures having been implemented in recent years, none of them is truly prepared for a global deployment, where failure tolerance and scalability are an essential requirement. This article presents an alternative concept for IoT Infrastructures, which focuses on enhancing the traditional centralized architecture, usually operated by a single entity, into...
Nowadays, the Internet of Things (IoT) is receiving more attention in commercial and academic research, especially about its security property. However, current protocols cannot satisfy the requirement of various IoT applications and introduce some problems. There are three typical problems: traditional public key infrastructure (PKI) apply in IoT will incur great overhead, wireless sensor network...
The Internet Protocol (IP) is ubiquitous in terrestrial and electromagnetic-carrier wireless networking. However, for very low-throughput underwater links (such as those using acoustic modems) the IP header introduces an unacceptable amount of data overhead for the small maximum transmission units available on underwater acoustic links. Nonetheless, it is becoming increasingly valuable to connect...
The term “Internet of Things” (IoT) refers to the expansion of Internet technologies to include smart objects by extensive deployment of exclusively identifiable distributed communication devices. The management of configuration in these devices, in particular, is a challenge due to the high heterogeneity in different communication protocols, communication sequences, and processing capabilities. We...
Because energy efficiency is gaining more importance these days and Bluetooth Low Energy (BLE) could be used to make use of potential everyday objects into Internet of Things (IOT) — a software, platform and vendor independent common service interface that can be used in such low resource devices has high potential. OPC UA is an emerging middleware solution that addresses the above points but is bulky...
The Internet of Things vision states that sensors and actuators shall be integrated into the global Internet to facilitate an interaction with and integration of the physical environment. The development of enabling technologies like uIPv6 and 6LoWPAN provide the basic requirements for this interconnection. However, a seamless Internet-connection and interconnection between sensors and actuators can...
At present, there are still many problems in the M2M system, and the most important of these issues is lacking a general M2M device model that could be widely used in various fields. So the main content of this paper is proposing a General M2M Device Model and discussing the function of each module in the model. Then the paper also discusses the communication of the General M2M Device Model and gives...
Application driven wireless sensor network (WSN) has a great prospect, interconnecting WSN to current network infrastructure is the research hotspot. An interconnection method is proposed, which connected large-scale WSN to Internet based on IPv6. To satisfy application requirements, IPv6 address is mapped based on geography location in WSN, and a geography location routing protocol named as clockwise...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
