Description

Ad-Hoc Routing Protocols checking system based on BeagleBone-Black

Technical field

It the utility model is related to mobile Ad-Hoc network fields, and in particular to a kind of based on BeagleBone-Black's Ad-Hoc Routing Protocols verify system.

Background technology

Under the overall situation of global mobile network communication technology high-speed development, an important branch as its field --- Mobile Ad-Hoc networks become the focus of industry specialists scholar's research already.Mobile Ad-Hoc networks are that one kind has specific use Network structure.

Compared with conventional communication networks, Ad-Hoc networks do not have strict control centre, in ad hoc networks all knots Point function phase is same, is the network of a complete peer-to-peer.Node coordinates respective behavior by agreement and special algorithm upon actuation, Organize themselves into a separate network rapidly under the support of no any network equipment.The simple and quick advantage of networking causes Ad- Hoc network is all widely used in fields such as sensor network, military communication, urgency communication services.

Due to the changeable characteristic of Ad-Hoc Network Mobilities so that the design optimization of Routing Protocol is always research emphasis.But At this stage in the Improvement to Routing Protocol, researcher's majority still rest on it is theoretical with PC ends software emulation, and by In real wireless communication scene, characteristics of radio channels is influenceed by many-sided condition, and Routing Protocol is only carried out The software emulation at PC ends can not go out the performance of Routing Protocol by actual response comprehensively, while also there is following shortcoming：

1）Software emulation is carried out to the performance of Routing Protocol at PC ends, actual environment can be ignored：Such as geographical environment, other letters The interference that number source, weather conditions or other uncertainties work Routing Protocol, therefore, obtained data can not be really and accurately Reflect the performance of Routing Protocol.

2）The checking data of only one-sided software emulation so that the convincingness of data is inadequate, and experimental data is more unilateral, Comprehensive, accurate detailed data can not be obtained.

3）The universality of simulation software is not high, not high to different protocol compatibilities.Use more complicated so that soft The study threshold and learning cost of part are too high.

Utility model content

In view of the shortcomings of the prior art, the technical problem that the utility model solves is that how to solve only to carry out Routing Protocol The software emulation at PC ends can not go out the performance issue of Routing Protocol by actual response comprehensively.

In order to solve the above technical problems, technical scheme provided by the utility model, which is one kind, is based on BeagleBone-Black Ad-Hoc Routing Protocols checking system, the self-organizing network being made up of the identical device node of multiple functions forms, its In connected by wireless signal between each device node, each device node includes：

Data processor, using BeagleBone-Black Open Source Platforms as hardware support, and transplantation scissors ruling system Linux system supports as software, carries ARM Cortex-A8 dominant frequency and has reached 1GHz processor, in 512MB DDR3 Deposit and have abundant extensive interface, be responsible for the processing of experimental data；

Wireless transceiver, formed using Ralink RT3070 as wireless network card, the network interface card integrated MAC/BBP and 2.4G RF one chips, it fully complies with IEEE 802.11n drafts 4.0 and 802.11 b of IEEE/g standards, is responsible for experimental data Forwarding and reception；

Sensor, external camera extraction vision signal, infrared sensor extraction infrared signal, sound it can pass as needed Sensor records voice signal, is responsible for providing experiment transceiving data；

Display screen, is 3.5 cun of LCD displays, running status and parameter for display system；

Movable power source, it is responsible for providing electric energy and there is good mobility.

The data processor is connected with wireless transceiver, display screen, movable power source respectively, and passes through nothing with sensor Line signal is connected.

Working-flow is as follows：

The first step：The software systems kernel of device node is compiled on PC and removes module useless in kernel Component carries out cutting compiling to kernel, and this measure can effectively reduce the lengthy and jumbled degree of software systems, improves system running speed, lifting Performance.By in the BeagleBone-Black systems of compiled Kernel Porting to device node.Treat normally to start After BeagleBone-Black (SuSE) Linux OS, corresponding LCD is installed drives and restart and light display screen.

Second step：The Ad-Hoc Routing Protocols verified will be needed to be transplanted in system and run, while by external wireless network Card insertion enters the USB jack of BeagleBone-Black systems, for carrying out the radio transmission-receiving function of data.Configure wireless network card ginseng Number enables the normal transceiving data of node, and the system initialization of whole equipment single node, which works, just to be completed.

3rd step：Out of doors on the spot in scene, while multiple equipment node is opened, route is run on multiple hardware nodes Agreement, and it is Ad-Hoc to configure device node mode of operation.After a period of time, ordered after treating network stabilization by ping-x The routing behavior of order observation respective nodes.

External environmental signals are collected using the external sensor of system simultaneously, are customized in corresponding slave node by opening upper strata MessageSender softwares find and destination host and forwarded the external environmental signals of collection in a network automatically, Destination host end can be with accurate reaction network Routing Protocol by opening the experimental data for the Test software records write Performance indications, such as transmission delay, the packet loss of data end to end.

The beneficial effect obtained using the technical solution of the utility model：

1st, in the case where resting on theoretical research and software emulation conventional routing protocols, the hardware system of design can be with more Simply and easily the Routing Protocol transplanting of design optimization is got on, has system bulk small, low in energy consumption, researcher can be facilitated to exist Equipment is taken in actual scene to the performance for the Routing Protocol for verifying institute's Improvement.

2nd, whole hardware system node carries a processor for having reached 1GHz based on ARM Cortex-A8 dominant frequency, 512MB DDR3 internal memories, and abundant extensive interface make it that performance is very excellent.Data-handling capacity is entirely capable of reaching and wanted Ask.

3rd, system overall volume only has size as mobile phone, can more conform to mobility and the polytropy of MANET, just In take equipment in actual scene to research.

4th, in terms of system software, Linux it is free, increase income, the advantage such as professional platform independence, researcher can be facilitated to be opened up Malleability is worked, and different upper layer software (applications)s, the checking to performance of route protocol can be customized above according to different experiment demands Can be more comprehensively accurate.
