Abstract

The invention discloses a task-driven multi-gateway cooperation method. A gateway controller in the scheme has global network state information; task scheduling and gateway switching based on a service request and network state information can be realized; multiple gateways exist in a wireless network; the various gateways use different frequencies as data channels, and cover an area together; themultiple gateways are extended to cover a relatively large area; once data of a sensor node is sent to any gateway node, the data can be cooperatively sent to a corresponding aggregation node in themultiple gateways; and thus, low throughput capacity due to multi-hop routing between sensor nodes can be effectively avoided. By means of the method, the gateways can be adaptively switched among 3G,LTE and Ethernet freely according to the network state; furthermore, the quality of service (QoS) of the network can be ensured; and the resource utilization rate, the QoS and the user experience canbe improved.

Description

technical field

[0001] A task-driven multi-gateway coordination method designed by the invention belongs to the technical field of wireless communication. Background technique

[0002] With the leap-forward development of user needs and network technology, the current informatization construction is facing many bottlenecks, mainly reflected in: 1) Various sensor subnets lack unified storage and processing of sensory data. Need to be strengthened; 2) Various heterogeneous wireless network access technologies coexist; 3) Various management service systems lack effective unification and integration, the phenomenon of information islands is prominent, and the coordination of object business processes is insufficient.

[0003] As wireless technology advances, emerging applications such as infrastructure monitoring and healthcare monitoring systems require more gateway nodes. A multi-gateway system can successfully avoid a single point of failure, but there are still many problem...
