Description: 定向扩散(Directed Diffusion, DD)协议在omnet++模拟器上的实现。原理:Sink 向所有传感器节点发送兴趣(兴趣是通过分配不同的属性值来表示不同任务的描述符) , 每个传感器节点在收到兴趣后将其保存在各自的 CACHE 中。每个兴趣项包含一个时间标签域和若干个梯度域。当一个兴趣传遍整个网络后, 从 Source 到 Sink 之间的梯度就建立起来了,梯度反映了网络中节点对匹配请求条件的数据源的近似判断。一旦Source 采集到兴趣所需的数据, 那么它将沿着该兴趣的梯度路径传输数据到汇集点或基站。-Directional proliferation (Directed Diffusion, DD) agreement omnet++ Realize simulator. Principle: Sink to all sensor nodes send interest (interest is through the distribution of different attribute values to express a different mission descriptors), each sensor node after the receipt of interest in the preservation of their respective CACHE. Interest of each tag contains a time domain and a number of gradient domain. When an interest throughout the network, from the Source to Sink gradient between the built up, the gradient reflects the network node on the request of the conditions of matching the data source to determine approximate. Once the Source of interest collected the required data, it would be interested in the gradient along the path to transmit data to the focal point or base station. Platform: |

Description: matlab 仿真程序可用于kalman滤波应用。- INTRODUCTION
This example simulates distributed control of a DC-servo. The example
contains four computer nodes, each represented by a TrueTime kernel
block. A time-driven sensor 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
to the actuator node, where it is subsequently actuated. The
simulation also involves an interfering node sending disturbing
traffic over the network, and a disturbing high-priority task
executing in the controller node Platform: |

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: MATSNL is a package of MATLAB M-files for computing wireless sensor node lifetime/power budget and solving optimal node architecture choice problems. It is intended as an analysis and simulation tool for researchers and educators that are easy to use and modify. MATSNL is designed to give the rough power/ lifetime predictions based on node and application specifications while giving useful insight on platform design for the large node lifetime by providing side-by-side comparison across various platforms. The MATSNL code and manual can be found at the bottom of this page. A related list of publications describing the models used in MATSNL is posted on the ENALAB part of the 2 project at http://www.eng.yale.edu/enalab/aspire.htm -MATSNL is a package of MATLAB M-files for computing wireless sensor node lifetime/power budget and solving optimal node architecture choice problems.

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: |
