The invention realize wireless sensor network applications and management separation of the distribution and management, it is convenient and flexible to manage systems and wireless sensor networks scale of the complexity of the application and user needs change, thereby reducing the wireless sensor network system workload.
Description
Technical field
The present invention relates to a kind of management method of wireless sensor network, mainly utilize distributed computing technology to solve the monitoring and the control problem of wireless sensor network, belong to Distributed Calculation, wireless sensor network and network management interleaving techniques application.
Background technology
Wireless sensor network is by having perception, the network that the sensor node of processing and wireless communication ability forms by the self-organizing mode, it can make us extend to more wide interactive space, obtain to center on our dynamic state information on every side, realization is for the peripheral world more accurate and deep understanding and control, thereby in military affairs, environment, healthy, family, traffic, manufacturing industry, commercial, facilities management, transportation, safety, there is wide application prospect in fields such as space exploration and disaster rescue, to people's live and work mode, industry development and change produce revolutionary impact.
But wireless sensor network be a kind of wireless self-organizing, fault-tolerance is high, dynamic, use relevant, data-centered novel information network, but under developments such as existing low-consumption wireless electrical communication technology, embedded computing technique, microsensor technology and integrated circuit technique, show as the little rapid large-scale of node volume dispose, can unmanned guard, but power supply energy is limited, communication capacity is limited, calculating and storage capacity are limited.Therefore, be necessary wireless sensor network is managed and reasonable distribution and control, to improve operational efficiency and reliability, to finish set application target, whole network is moved more economically, but the management to wireless sensor network is different from other existing information networks, needs to be fit to the management method of its characteristic.
Mobile proxy technology is a kind of based on network distributed computing technology, diffusing, loosely-coupled with a component in essence, movably intelligence structure realizes in distributed network environment that high efficiency cooperates with uniting mutually between colony and finds the solution, and solves conflict and contradiction under multiple cooperative strategy and the scheme.Mobile agent has independence, initiative, reactivity, mobility, characteristic such as social and intelligent, form with hardware or software, can realize the collaborative and autonomous of system, can finely be applied in the network management, and solve more insoluble key issues in present this field.Especially in wireless sensor network limited bandwidth, energy constraint, unsettled dynamic radio environment, mobile agent helps to dispose flexibly and extended network management intelligence, makes up efficiently, the management system of autonomy initiatively; Make distribution and control as close as possible information source, save bandwidth, reduce the perception data redundancy, reduce data traffic and communication overhead; Realize the task scheduling strategy of dynamic management mode and high flexible; Conserve energy effectively prolongs network system life cycle.
Existing wireless sensor network way to manage often cause aggregation node and (or) the outer application system work load of network is overweight; When the wireless sensor network scale enlarged, wireless sensor network management overall response time was longer, system's poor astringency; Because system scale and application become increasingly complex, and add the change of user's request, the wireless sensor network management logic is difficult for the expansion upgrading.
Summary of the invention
Technical problem: the objective of the invention is to make up an Efficient and Flexible distributed monitoring and control method for wireless sensor network, improve wireless sensor network operational efficiency and reliability, a kind of wireless-sensor network distribution type management method based on mobile agent is provided, make Internet resources obtain the most effective utilization, and continuous, reliable and stable service is provided.
Technical scheme: wireless-sensor network distribution type management method of the present invention is: the mobile agent of example, in hardware is distributed in the wireless sensor network, these mobile agents have sufficient energy supply, stronger processing and wireless communication ability, safety assurance ability reliably than the general node in the wireless sensor network, use movably dynamic management network (being called the mobile agent net) of concrete composition in service at wireless sensor network, monitoring and control service to wireless sensor network are provided.
One, architecture
Architecture of managing based on the wireless-sensor network distribution type of mobile agent of the present invention comprises three-decker: network layer, mobile agent layer, service layer.Network layer is based on the support system of the wireless-sensor network distribution type management of mobile agent, and being embodied in the all-network node self-organizing that comprises the general node of wireless sensor network and aggregation node and mobile agent is the hardware infrastructure of whole architecture.The mobile agent layer is based upon on the basis of network layer, is displaced in the wireless sensor network of being managed with example, in hardware, has the mobile agent of showing as net, forms the management infrastructure of whole architecture.Service layer is based on the wireless-sensor network distribution type management of mobile agent and uses abstraction hierarchy, be embodied in the basic management service of using, comprise performance management service, fault management service, configuration admin service, accounting management service and safety management service etc. towards wireless sensor network.
