Embodiment Construction

[0038] The system composition of the present invention is:

[0039] 1) Two-layer mobile Agent application model, the application layer and the system service provider layer under the application layer, with a clear boundary between the system and application software;

[0040] 2) The application layer is composed of multiple user-customized dynamic Agents;

[0041] 3) The system service providing layer includes multiple system agents, which provide multiple system services in the form of static agents; most of the general-purpose functions of the system are provided at this layer;

[0042] 4) A mobile agent execution environment located on the network layer;

[0043] 5) An active packet manager located at the network layer;

[0044] 6) The system supports active sensor networks.

[0045]Figure 1 is the active sensor network protocol stack and functional module mapping diagram, which is divided into three layers, node operating system, execution environment and active applic...

Abstract

The invention discloses a design of an active wireless sensor platform based on middleware. The present invention designs a general-purpose middleware system supporting active wireless sensor networks. The middleware system can run on sensor network nodes with limited resources. The system provides network service management, data management and task management functions, and provides user-customizable The network node service function allows it to be applied in different sensor network environments to meet the requirements of code sharing, reduce the development cycle of sensor network application programs, and increase the robustness of sensor network software. The technical solution adopted in the present invention is: a general-purpose middleware system for active wireless sensor networks based on mobile Agent technology, the system includes an application layer composed of a plurality of dynamic Agents, a plurality of system service modules located under the application layer, and a A mobile agent execution environment on the network layer, and an active packet manager on the network layer.

Description

technical field [0001] The invention generally relates to the field of wireless sensor networks, and specifically refers to a middleware system and an implementation method for supporting active sensor networks realized by using mobile Agent technology. Background technique [0002] A wireless sensor network is a special AdHoc network organized by a large number of low-power, multi-functional micro wireless sensors. It has self-organization, multi-hop routing, dynamic topology, limited hardware resources and power capacity, and a large number of nodes. With dense distribution and data-centric features, it can be applied to military, environment, health, family, business and other fields. Compared with traditional networks, sensor networks have the following characteristics: 1) Extremely limited resources; 2) There are no "pure" intermediate nodes such as routers and switches, and each node in the network simultaneously undertakes the functions of routing and "terminal" syste...
