Problems solved by technology

[0006] In the process of application program development, the original technology uses the unique API of wireless sensor network for network access, which brings difficulties to the parallel development in the development process. Application program developers must wait for wireless network card firmware developers to complete the protocol stack The development of the network part can only be carried out after the construction of the network. At the same time, the non-standardization of the network access API function brings difficulties to the portability and versatility of the application program. When the network form changes, the application program will also become invalid. Application program development Personnel carry out new development for new network forms, reducing work efficiency and duplicating labor. Therefore, this has also become a shortcoming that wireless multimedia sensor networks cannot be compatible with SOCKET network programming specifications

Embodiment Construction

[0032] Below, the substantive features and remarkable progress of the present invention will be further elaborated through specific embodiments. However, the invention is by no means limited to the specific embodiments described.

[0033] In the specific implementation, the platforms are mainly PCs and handheld devices. Taking the PC running the Windows operating system and the handheld device running Windows CE as examples, the specific embodiments are described in detail. Its specific hierarchical structure diagram is as follows Figure 4 shown.

[0034] Applications that comply with the SOCKET specification call Windows API, and data enters the operating system from the APP. The Windows operating system maintains an IP protocol stack and provides an NDIS interface to the outside to adapt to physical network cards of different network forms. Here, the virtual gateway is constructed In the lower layer of NDIS, it is used to obtain the IP data packet transmitted from the ope...

Abstract

The invention relates to a method for processing an IP network to a wireless multimedia sensor network. The method is characterized in that the virtual gateway mode is utilized to access the wireless multimedia sensor network to the IP network; the virtual gateway obey that the wireless multimedia sensor network can be accessed through the application program of SOCKET network programming code; the virtual gateway is capable of dynamically loading to convert IP data and multimedia sensor network protocol data on different operation platforms and is corresponding to a network driving program of an operation system. According to the method, a virtual gateway middleware is developed to solve the problem of transparent transmission of data of the wireless multimedia sensor network and the IP network and the problem of poor transferability and universality of the application program of the wireless multimedia sensor network.

Description

technical field [0001] The invention relates to the problem that a wireless multimedia sensor network is connected to other networks such as an IP network, which can be used for a wireless multimedia sensor network system running a private protocol, and belongs to the field of information technology. Background technique [0002] With the development of wireless sensor network technology, the type of data packets transmitted in the network has gradually developed from a relatively simple data packet to a multimedia type of data packet, and the demand for data by applications has gradually increased, and existing network applications directly access The form of wireless network card data can no longer meet the needs of development. How to make IP data packets "transparent" in wireless multimedia sensor networks, how to increase the portability of applications, and how to significantly reduce the burden on developers have become problems that need to be solved in wireless multi...
