Description Building Wireless Sensor Networks: Application to Routing and Data Diffusion discusses challenges involved in securing routing in wireless sensor networks with new hybrid topologies. An analysis of the security of real time data diffusion—a protocol for routing in wireless sensor networks—is provided, along with various possible attacks and possible countermeasures. Different applications are introduced, and new topologies are developed. Topics include audio video bridging AVB switched Ethernet, which uses the representation of a network of wireless sensors by a grayscale image to construct routing protocols, thereby minimizing energy consumption and data sharing in vehicular ad-hoc networks. Existing wireless networks aim to provide communication services between vehicles by enabling the vehicular networks to support wide range applications.

The IEEE With the emergence of Internet of Things , many other proposals have been made to provide sensor connectivity.

Wi-SUN [22] connects devices at home. WSNs may be deployed in large numbers in various environments, including remote and hostile regions, where ad hoc communications are a key component. To conserve power, wireless sensor nodes normally power off both the radio transmitter and the radio receiver when not in use. Recently, it has been observed that by periodically turning on and off the sensing and communication capabilities of sensor nodes, we can significantly reduce the active time and thus prolong network lifetime.

However, this duty cycling may result in high network latency, routing overhead, and neighbor discovery delays due to asynchronous sleep and wake-up scheduling. These limitations call for a countermeasure for duty-cycled wireless sensor networks which should minimize routing information, routing traffic load, and energy consumption. Researchers from Sungkyunkwan University have proposed a lightweight non-increasing delivery-latency interval routing referred as LNDIR.

This scheme can discover minimum latency routes at each non-increasing delivery-latency interval instead of each time slot. Simulation experiments demonstrated the validity of this novel approach in minimizing routing information stored at each sensor. Furthermore, this novel routing can also guarantee the minimum delivery latency from each source to the sink.

Performance improvements of up to fold and fold are observed in terms of routing traffic load reduction and energy efficiency, respectively, as compared to existing schemes. They more strongly resemble embedded systems , for two reasons. First, wireless sensor networks are typically deployed with a particular application in mind, rather than as a general platform. Second, a need for low costs and low power leads most wireless sensor nodes to have low-power microcontrollers ensuring that mechanisms such as virtual memory are either unnecessary or too expensive to implement.

However, such operating systems are often designed with real-time properties. TinyOS is perhaps the first [26] operating system specifically designed for wireless sensor networks.

TinyOS is based on an event-driven programming model instead of multithreading. TinyOS programs are composed of event handlers and tasks with run-to-completion semantics.

When an external event occurs, such as an incoming data packet or a sensor reading, TinyOS signals the appropriate event handler to handle the event. Event handlers can post tasks that are scheduled by the TinyOS kernel some time later. Online collaborative sensor data management platforms[ edit ] Online collaborative sensor data management platforms are on-line database services that allow sensor owners to register and connect their devices to feed data into an online database for storage and also allow developers to connect to the database and build their own applications based on that data.

Examples include Xively and the Wikisensing platform. Such platforms simplify online collaboration between users over diverse data sets ranging from energy and environment data to that collected from transport services. The architecture of the Wikisensing system [28] describes the key components of such systems to include APIs and interfaces for online collaborators, a middleware containing the business logic needed for the sensor data management and processing and a storage model suitable for the efficient storage and retrieval of large volumes of data.

Simulation[ edit ] At present, agent-based modeling and simulation is the only paradigm which allows the simulation of complex behavior in the environments of wireless sensors such as flocking.

Agent-based modelling was originally based on social simulation. Security[ edit ] Infrastructure-less architecture i. The experiments started with the receiver positioned 1 m from the transmitter. The receiver was then moved away from the transmitter in increments of 1 m until the signal was lost. At each distance, data were collected for 30 s, providing transmissions from the sensor node.

The trends shown in these plots are typical of other tests. RSSI is shown in Fig. The downward trend of RSSI with distance matches the expected decrease in the signal strength with the square of distance as described by Eq. The oscillations in the data at approximately 10 m were seen in most of the tests. The data are once again plotted as the average of the LQI computed over the transmissions at each distance and 5.

The maximum distance for reliable communication will be called as the range of reliability. Data from such a situation can serve as a baseline for performance within a building. Received signal strength indication vs. Link quality indication vs.

Packet delivery rate vs. RSSI vs. It is interesting to note that the uncertainty increases with distance and with decreasing LQI. Plots such as those shown in Figs. The trends were similar for all plots, though low power levels and highly obstructive materials resulted in scattered data even at low distances. For example, Figs. Uncertainties are similar to those shown in Figs.

LQI vs. PDR vs. A key component of this work was to investigate the relationships between the three metrics that could be used to assess the Fig. PDR for transmission on grass at 0 dBm. Equivalent distance Spacing between sensor nodes and receivers of the data from those nodes is a key component in knowing the required density of transmitters in a wireless sensor network. Here, it is proposed to use an equivalent Fig.

This distance is called the range of reliability. For example, it is not expected that signals propagating through gypsum board would have a larger range than those traveling in a line-of-sight scenario. Nevertheless, these data will be used to provide general conclusions on the results. For the equipment used here, the maximum distance between transmitter and receiver to assure reliable operation would be approximately 65 m. Plywood and gypsum board obstructions had little effect on this distance.

For example, one could state that the equivalent of a 65 m range in line-of-sight operation would be approximately 20 m when the signal propagated through the door that was tested.
