Description
Technical field
The present invention relates to the wireless sensor network technology field, particularly relate to a kind of wireless sensor network and intend real analogue system.
Background technology
Wireless sensor network and mobile Ad-hoc network are approximate; Form by thousands of up to a hundred communication nodes; The problem that the research of the two need solve is approximate; But wireless sensor network has the characteristics of self: (1) wireless sensor network protocols layer operation is the physical measurement data-driven that is obtained by bottom sensor with using, and the measurement data characteristic has determined network traffics, even topology.(2) energy of wireless sensor network node is limited.
The These characteristics of wireless sensor network makes that the true performance of analytical model and prediction upper-layer protocol and network system is comparatively difficult.Emulation is that the research wireless sensor network is requisite, is used for testing new application and agreement.
Emulation testing realizes network state and node state with software approach, abstract node hardware characteristics and channel characteristics simply, thus estimate the performance of wireless sensor network.Emulation testing can be carried out a plurality of comparisons with quasi-protocol; Good method of testing and evaluation means are provided on functional layer; But emulation testing depends on Mathematical Modeling, because computation complexity, when solving practical problem; Mathematical Modeling need be done to simplify in large quantities and handle, thereby greatly reduces emulation testing result's confidence level.Wireless sensor network is deployed in the complicated rigorous environment usually, and there are the height dynamic in network state and node state, and the ideal model of emulation testing is difficult to describe this complicated rigorous environment influence.Invisible, uncontrollability just because of hardware characteristics and channel characteristics; The result that emulation testing obtains can not be used as complete credible foundation and remove to dispose wireless sensor network; Need further test through actual environment, thus the state evaluation of acquisition wireless sensor network.
Summary of the invention
Technical problem to be solved by this invention provides a kind of wireless sensor network and intends real analogue system, can reduce or avoid the reciprocal of wireless sensor network system design, improves development efficiency.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of wireless sensor network to intend real analogue system, comprise emulation tool, physical testing module, database, model correcting module and parameter correcting module; Said emulation tool is used to carry out the real emulation of plan of wireless sensor network, and wherein simulation model obtains through said model correcting module, and parameter is obtained through said parameter correcting module; The simulation protocol that the said emulation tool of said physical testing module online updating obtains is used to obtain various physical testing parameters; Said database is used to preserve the physical testing data; Said model correcting module is used for the physical testing data correction simulation model according to said database, and the encapsulation simulation model; Said parameter correcting module is used for carrying out intellectual analysis according to the physical testing data of said database parameter is set.
Said physical testing module is wireless sensor network physical testing platform or the physical testing platform built certainly.
Said database is database or the non-database of increasing income of increasing income.
Beneficial effect
Owing to adopted above-mentioned technical scheme; The present invention compared with prior art; Have following advantage and good effect: the present invention constantly removes to revise simulation model according to the result of physical testing; Make simulation model approach each element of real wireless sensor network (like node, channel, power consumption etc.), also the parameter setting near true environment is provided simultaneously for emulation tool.Intend real emulation and make emulation testing and physical testing interactive, reduced that because of simulation model or parameter the improper wireless sensor network design error that causes being set.
Description of drawings
Fig. 1 is a structured flowchart of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Execution mode of the present invention relates to a kind of wireless sensor network and intends real analogue system, and native system couples together previous emulation testing and two tests of not theing least concerned of physical testing, and the emulation testing of true environment more true to nature is provided.As shown in Figure 1, wireless sensor network is intended real analogue system and is comprised emulation tool, physical testing module, database, model correcting module, parameter correcting module.Emulation tool mainly is to intend real emulation as wireless sensor network, and wherein simulation model obtains through the model correcting module, and parameter is obtained through the parameter correcting module; The simulation protocol that the physical testing module can the online updating emulation tool obtains is used to obtain various physical testing parameters; Database is used to preserve the physical testing data, conveniently calls; The model correcting module then is according to the physical testing data correction simulation model in the database, as according to the actual energy consumption data correction energy consumption model that records, approaches actual consumption and changes, and the encapsulation simulation model; The parameter correcting module carries out intellectual analysis according to the physical testing data in the database parameter is set, and as the size of packet data package in the suitable network is set according to test data, helps reducing the reasonless humour that simulation parameter is provided with, and improves simulation efficiency.Wherein, the physical testing module can be a wireless sensor network physical testing platform, also can be from the physical testing platform of building.Database can be the database of increasing income, and also can be the non-database of increasing income.
Emulation tool and physical testing module exist alternately each other among the present invention, and this is through following dual mode alternately: the 1) simulation protocol that can the online updating emulation tool obtains of physical testing module; 2) the physical simulation module realizes through changing simulation model and parameter the influence of emulation tool.Interaction through above-mentioned dual mode has reduced because of simulation model or parameter are provided with improperly, causes wireless sensor network design error.
Be not difficult to find; The present invention constantly removes to revise simulation model according to the result of physical testing; Make simulation model approach each element of real wireless sensor network (like node, channel, power consumption etc.), also the parameter setting near true environment is provided simultaneously for emulation tool.Intend real emulation and make emulation testing and physical testing interactive, reduced, cause wireless sensor network design error because of simulation model or parameter are provided with improperly.
