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...
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...
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...
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...
Recent technological advancements in the field of nanotechnology have increased the computation power of the wireless nodes while adhering to the energy constraints. This has made the use of the Wireless Sensor Networks (WSNs), more widespread, used in applications such as area monitoring, industrial monitoring, vehicle detection or military monitoring. Sensor nodes have made it possible to collect...
Wireless Sensor Networks (WSNs) are at high speed gaining in popularity. Because of this increased adoption, the need for integration with existing technologies becomes more prominent. In practice, a WSN is often deployed in environments where both wired and wireless data networks are also present. Consider for instance a WSN which acts as a climate monitoring or fire detection system in a large office...
The converge cast traffic pattern (many-to-one data communication) of wireless sensor networks leads to high load at nodes that are aggregating data. Therefore, we need to distribute the entire traffic load by deploying multiple data collectors and each node should select a collector node to access. Additionally, with the progress of IPv6-based wireless sensor networks, advantages of IPv6 protocols...
Recent trends in Wireless Sensor Networks (WSNs) have suggested converging to such being IPv6-based. To this effect, the Internet Engineering Task Force has chartered a Working Group to develop a routing protocol specification, enabling IPv6-based multi-hop Wireless Sensor Networks. This routing protocol, denoted RPL, has been under development for approximately a year, and this paper takes a critical...
This paper proposes a resolution of using wireless sensor networks to improve the productivity of agriculture. The application of the sensor networks is introduced briefly at first, then the design and implementation of the hardware and software of the sensor nodes and sink node is discussed in detail. The experimental results show that the system can work effectively in monitoring the ecology environment...
Mobile agents are often used in wireless sensor networks for distributed target detection with the goal of minimizing the transmission of non-critical data that negatively affects the performance of the network. A challenge is to find optimal mobile agent routes for minimizing the data path loss and the sensors energy consumption as well as maximizing the data accuracy. Existing approaches deal with...
Directed Acyclic Graphs (DAGs), rooted at popular/default destinations, have emerged as a preferred mechanism to provide IPv6 routing functionality in large scale low power and lossy networks, that include wireless sensor networks and those based on power line communication. A DAG maintains its acyclic nature by requiring that each DAG node must have a higher 'rank' than any of its DAG parents. While...
The paper introduces wireless sensor network's route protocol, then the difference between traditional wireless network and wireless sensor network is analyzed, and the MSAODV route protocol based on AODV route protocol are raised and implemented, the simulation soft tool NS-2 is used, and end-to-end delay and the normalized routing load are chosen to evaluate the performance of the MSAODV. The modified...

This new standard is designed to help constructing the network infrastructure by integrating with the TCP/IP network with the ZigBee network. A new approach for WSN deployment...
The next generation of wireless sensor networks will integrate communication systems beyond the third generation paradigm. As a result of this integration, the new communication systems will be fed by the sensor networks with information gathered from the environment, achieving context awareness. To reach the necessary end-to-end connectivity between all-IP networks and sensor networks, the IETF 6LoWPAN...
