Description: Example: Distributed Wireless Control System，可用于无线传感器网络中-This example shows distributed control of a DC-servo using
communication over a wireless network. The example also shows how to
simulate power consumption and how to use the battery block. The model
contains two computer nodes located 20 m apart, each represented by a
TrueTime kernel block. A time-driven sensor/actuator node samples the
process periodically and sends the samples over the network to the
controller node. The control task in this node calculates the control
signal and sends the result back to the sensor/actuator node, where it
is actuated. The wireless communication link is at the same time
subject to a simple power control scheme. Power control tasks running
in both the sensor/actuator node and in the controller node
periodically send out ping messages to the other node to test the
channel transmission. If a reply is received, the channel is assumed
to be good and the transmission power is lowered. If on the other hand
no reply is received, then the transmi Platform: |

Description: Estimating the positions of sensor nodes is a fundamental and
crucial problem in ad hoc wireless sensor networks (WSNs).
In this paper, an accurate node localization method for WSNs
is devised based on the weighted least squares technique with
the use of time-of-arrival measurements. Computer simulations
are included to evaluate the performance of the proposed
approach by comparing with the classical multidimensional
scaling method and Cram´ er-Rao lower bound. Platform: |

Description: 针对煤矿井下巷道狭长，信号多径效应明显，接收信号强度（RSSI）测距算法受井下环境影响大，定位精度低的情况，提出了一种信标节点链式部署结构下的动态RSSI测距算法，该算法以信标节点间的距离和它们间测量到的RSSI值为参考，计算巷道内实际环境下的路径衰落指数，以提高RSSI测距算法对环境的适应性。-A dynamic RSSI location algorithm is proposed based on the beacon nodes chain deployment of tunnel Wireless Sensor Networks and the algorithm takes the distance and the corresponding RSSI between the adjacent beacon nodes into account to calculate the actual path loss parameter in the tunnel, thus improving the environmental adaptation of the location algorithm.

Description: Wireless Sensor Networks (WSN) is different than the Cellular Networks as I mentioned earlier.
A WSN is composed of a large number of sensor nodes that communicate using a wireless medium (air).
The sensor nodes are deployed randomly in the environment to be monitored.
The sensor nodes distributed in ad hoc structure.
In WSN there is no base station and not all nodes hear each other.
The WSN is a multi-hop network.
Basic part of my code is to randomly place the sensor nodes in the given space then connecting each two nodes if the distance between them less than or equal to the communication radius. Platform: |
