Embodiment Construction

[0045] exist figure 1 Above, it shows the key components and their respective roles in the routing unit, as well as the data and control traffic flow within a layered network reference model (such as the OSI model). The first layer (L1) is responsible for the physical transmission of data bits. This layer is used to measure and obtain the state and quality of physical characteristics, such as the capacity and state of the channel, the number of data packets sent (sending rate) and the queue size. These The information is passed to the third layer (L3) to the data collection device 102 . The data acquisition device transmits the obtained and analyzed status information to the routing unit 101 . This unit 101 performs routing calculations to determine the route for the data packet currently to be sent, it also determines when and how the routing table should be updated. Routing unit 101 handles sending and receiving data traffic and control traffic. It handles the processing ...

Abstract

The invention puts forward a measuring system of stability of a wireless self-organized network route and method thereof relating to the field of Adhoc network and stability measurement of the network. The system is composed of a positioning module, an obtaining module and a calculation module. Firstly a node translational speed vector and a position vector datum obtained by the positioning module and a transmission speed and a channel capacity datum obtained by the obtaining module are added to a RREP package of a route protocol to send to a source node, then analyzing and calculating the data information according to measuring calculation method provided by the invention and obtaining the dynamic stable domain of the network route by the source node. Furthermore, the dynamic stable domain obtained rapidly and linearly judges stability of the route.

Description

technical field [0001] The invention relates to an evaluation system of routing stability in a wireless self-organizing network, and in particular provides an adaptive routing stability measurement system suitable for Ad hoc networks with strong node mobility. Background technique [0002] In recent years, a mobile communication network called wireless self-organizing network (also known as Ad hoc network) has developed rapidly. It is a temporary self-organizing network composed of a group of mobile nodes (usually computers) with wireless transceiver The network system has the characteristics of no central control, node mobility, and multi-hop wireless connection. It can be widely used in hostile environments where it is difficult to build fixed communication facilities, such as field communications, emergency search and rescue, and temporary meetings. In this network, each mobile node is capable of operating as a base station or router for other mobile nodes, thereby elimin...
