Software Defined Networking (SDN) is a developing networking paradigm that advocates a complete overhaul of the conventional networking. SDN decouples the control logic from the data forwarding functionality; which traditionally are coupled on the network device. The coupling stifles innovation and evolution because the network often becomes rigid. Software Defined Wireless Sensor Networks (SDWSN)...
In wireless sensor networks, Information-Centric Networks (ICN) are used as the next generation network architecture to perform non-TCP/IP communications. Meanwhile, Disruption/Delay Tolerant Networks (DTN) architecture has solved the problem of unable to communicate caused by frequent interruptions, node mobility or lacking of energy by storing the requested data in nodes' memory. However, the users...
With the increasing use of Wireless Sensor Networks, the privacy of the user is of main concern. The sensors maintain a layer 2 address that lasts for the node lifetime. As a consequence, an eavesdropper can easy trace the user and his activities, even in case the nodes send ciphered traffic.We propose a 6LoWPAN-ND extension to improve privacy and overcome the traceability of the user. With our method...
Internet of Things(IoT) has become an emerging area of research. 6LoWPAN is introduced to connect large number of things which are nothing but sensors of different capabilities. In 6LoWPAN, there are mainly two routing schemes, named as route-over (assembly mode) and mesh-under (direct mode), based on which layer is involved during routing decisions. Modified route over comprises the advantages of...
Smart Grid (SG) is an intelligent and adaptive energy delivery network that combines the traditional power grid and IT communication network. It aims to provide more efficient, better fault-resilient and reliable energy support. Robust communication architecture is the key that differentiates Smart Grid from the traditional energy delivery system. IP enabled devices are necessary to build such network...
Named Data Networking (NDN), a revolution of the IP architecture, provides an information-centric routing for designing the unified Internet of Things (IoT) network protocol. However, the data forwarding scheme exploited by the current NDN generates lots of communication overhead and invalid caching hits, which is not suitable for IoT. This is because there exist large amounts of weak network devices...
The Internet of Things requires a naming service that can also be beneficial for searching for services and applications. To avoid the traditional DNS approach in which a DNS server provides mapping of names to IP addresses in its domain, we propose a novel network service called DINAS (DIstributed NAming Service). It is based on three pillars: 1) Bloom filters for creating compact names from node...
Today, there exist several standards based and proprietary based protocols that can be used in Wireless Sensor Network (WSN) applications. Proprietary technologies are difficult to integrate into larger networks and currently available Internet-based services. The use of IP based technologies allows easy integration with existing network infrastructure. Interoperability has always been a major concern...
This article presents a future-driven routing architecture for Internet of Things (IoT). This IoT is a novel concept involving a new concept regarding a set of things with the same routing and service polices, denoted by an autonomous system of things (ASoT). In IoT, an ASoT would be connected not only to the others but legacy autonomous systems (ASs) for the Internet in a wide variety of scenarios...
Emergency networks, especially networks of disaster recovery, have been the focus of active research in many countries. That is due to the broad impact of disasters' frequent occurrences, and casualties. The Hybrid Network Emergency Communication (HNEC) protocol is proposed [9] which establishes a heterogeneous network disaster recovery (NDR) that includes non-IP systems to achieve emergency requirements...
Internet is taking vital role in our communications system it can be infrastructure oriented or infrastructure less; the slow convergence of routing protocols after a network failure results in growth in problem. To ensure fast recovery from both i. e. link and node failures in wireless networks, we present a new recovery scheme called Enhanced Multiple Routing Configurations (EMRC). EMRC is based...
IPv6-based wireless sensor networks (IPv6-WSNs) are playing an important role in the extension of the smart grid to residential premises. Unlike traditional WSNs, IPv6-WSNs are based on IP protocol and do not need an application-layer translator. They can greatly save developing time and improve the efficiency for end-to-end communications. As configuring node with unique address is a prerequisite...
As the world is moving towards the “Internet of Things” [1], Internet Protocol enabled wireless sensor network is becoming an important research area. In order to make it possible and to facilitate transmission of IPv6 packets over low powered networks, 6LoWPAN [9,11] has been introduced. 6LoWPAN incorporates an adaptation layer between network and data link layers. Two routing schemes are used in...
Several applications of Wireless Sensor Networks (WSN) demand information only from sub-regions of the monitored area. The user establishes the region of interest (RoI) and requires the WSN to collect data only inside this region. This kind of query is called spatial query. The state of the art of spatial query processing considers, in general, that nodes do not fail. However, nodes can be destroyed,...
Wireless Sensor Network (WSN) is one of the most demanding research topics prevalent in the modern research domain. WSN consists of densely deployed sensor nodes in the area which is to be sensed or monitored. Each sensor node is a tiny and power constrained device which is assigned the task of monitoring. Sensor networks have a very wide range of application and so they are much in demand. Every...
Network addressing is a traditional problem in communications network. IP addressing which can fully reflect the characteristics of Wireless Sensor Network will provide good support for the design of network routing and management protocols. The location information which is important in most of WSN application can be used to simplify routing policy, and is also supported by IPv6. In this paper, we...
Wireless sensor network is a revolution of information collection and perception field, which has been draw much more application gradually. However, The WSN with characteristic of self-organization, multi-hop, dynamic topology and limited energy resources, which make the network to prolong it's lifetime become extremely difficult. This paper analyzed variety multicast protocols in existence and the...
In order to make up for deficiencies in the current mine-security monitoring system, the paper proposes a mine-security real-time monitoring system based on 6LoWPAN. In the system, WSN achieves the direct access to the internet and does not need a specific gateway to fulfil the protocol conversion or the protocol bearing, and in the meanwhile WSN achieves the end-to-end communication with the Internet...
The development of wireless technologies makes it necessary to find a way of improving Transmission Control Protocol (TCP) efficiency with regards to optimal utilization of wireless channel capacity. This paper describes a modification to the TCP congestion control for use in wireless sensor networks. It shows that by slightly modifying the algorithm of the TCP, it can be made to respond better to...
