So far, the standard solution has been to insert a light shield, called a coronagraph, along a telescope's light-gathering path.
Finally, concluding remarks and future research directions are presented in Section 7. Data-gathering path can be selected based on the diverse criteria.
Thus, the purpose of localized schemes is to reduce the communication overhead for the construction of a data-gathering path, which is desirable for energy-constrained wireless networks.
For data-gathering path construction, nodes have to determine the next node to forward the data to the sink with a parent selection strategy.
Figure 3 The comparison of localized tree construction schemes: the average ETX of data-gathering paths with respect to link threshold.
In mobile data gathering tour path, it is a minimum path for the ME to collect the data from respective sensors.
To illustrate the effect of hop count on the data gathering tour path, N,L and Tr are set to be constant and assigned the values 200, 200 m and 30 m, respectively.
Considering that 1 m/s is the average speed of ME, the time needed to finish the data gathering tour path is obtained by dividing the total distance over the average velocity (i.e. 13.30 m /1 s ).
The ME starts the data gathering tour path from the BS and traverses through all CTPs, collecting data packets from the respective SPPs and then eventually returning to the BS. Figure 3 illustrates the mobile data gathering, where the sub-set of sensor nodes selected as SPPs, denoted by black filled circles, aggregate the data from affiliated sensors.
Katz and I had arrived in the Smoky Mountains to join the gathering of the Green Path.
Towns in the path of gathering cyclones are routinely reported to "brace" for their arrival.
