Sentence examples for by the sensor network from inspiring English sources

Finally, we present simulation results on the lifetime of IEEE 802.15.4 wireless sensor networks, which enrich the proposed analytical framework and show that typical networking performance metrics (such as throughput and delay) are influenced by the sensor network lifetime.

The vehicle detection information that is calculated by the sensor network is stored inside the network until an opportunity arises to transfer that information back to the base station.

Facts nodes model statuses occurring in the observed scenario; they can be directly perceived by the sensor network or be the result of some process implemented in some technology.

Figure 9 Number of PSO-based Cluster Head Selection Rounds Supported by the Sensor Network. Figure 10 illustrates the amount of energy consumed by the sensors over a simulation period of 800 seconds.

As stated in Definition 1, nodes in the graph can be distinguished in: Fact nodes, Process nodes, and Technology nodes: Facts nodes model statuses occurring in the observed scenario; they can be directly perceived by the sensor network or be the result of some process implemented in some technology.

The results and conclusions from these figures, which are also supported by data from the sensor network field trials in Section 3.3, are as follows: Figure 2 indicates that the microphone is subject to more noise or rather variations than the geophone, provided that the proposed models are relevant.

Since VSN's energy is usually limited, reducing the energy consumption by 7.58% means that we are increasing the lifetime of the sensor network by 7.58%.

Noting that the measurements of these sensors are generally noisy of certain degree, it is crucial and interesting to analyze how the accuracy of localization is affected by the sensor errors and the sensor network, which may help to provide guideline on choosing the specification of sensors and designing the sensor network.

Every cluster head may be compromised or captured in the sensor network by adversaries.

In particular, we will focus on distributed localization, in which the device is not localized by a central unit that collects and processes the data acquired from the sensor network, but by the network itself.

The initialization provided by the GA succeeded in accelerating the sensor network design procedures.
