5. The method of claim 1, wherein the first polling messages are sent to the wireless transceiver unit over a Common Link Channel and the status information sent in response to the first plurality of polling messages is received from the wireless transceiver unit over a Common Access Channel....
At this point node i becomes the new end node of the chain. This 296 procedure continues until all sensor nodes have joined the chain, so that a branching chain is finally 297 formed. Figure 8 is showing the chain between node for every sector. Algorithm 2: ChainFFciioggnuusrreter8u8.....
Moreover, the selected device for image capture, such as a video camera or webcam, must have USB and must adapt its hardware characteristics to the hardware characteristics of the access point or wireless router. Finally, the camera should be able to rotate, with the aim of having a larger...
Regarding FDMA—Frequency Division Multiple Access and CDMA—Code Division Multiple Access MAC protocols, the medium can be accessed using a frequency band or a specific code, respectively. TDMA-based are the mainly used MAC protocols in WSNs, since the implementation of FDMA requires nodes that ...
In Figure 1b, each station in Figure 1a is represented as a point in a 2-dimensional space, whose x and y dimensions are distance and price, respectively. Comparing two stations a and b, both the distance and the price of a are lower than those of b. In this case, a is said to...

A point that should be considered when combining VF and PSO or CPSO is that the force computed in VF algorithm is inserted only on the position parameters of sensor, which means, to compute the speed of position change, parameters such as direction from the force inserted on the sensors, ...

Code division multiple access (CDMA) is considered for physical transmission. A novel multiple access scheme for aerial sensor networks employing adaptive antenna arrays with spatial reuse is proposed in [25]. A priority-based optimized frame selection (POFS), a circularly optimized frame selection ...
The point is that we cannot use acknowledgement messages all the time due to their high resource consuming nature. The reputation-based trust model of the social network research field will help us to find the upstream nodes that have more opportunities to be informative for any time other than...
