Embodiment Construction

[0044] The attribute-related data aggregation method proposed by the present invention is described as follows with reference to the drawings and embodiments.

[0045] The present invention is characterized in that a data aggregation layer is added between the routing layer and the application layer, and the routing layer provides an interface to the data aggregation layer: getDanymicParent (), this interface provides the next-hop dynamic address of the data packet based on the potential energy field model, and can make the data packet containing Packet spatial aggregation of related information is enhanced. The data aggregation layer controls the aggregation operation through the queue length in the buffer pool and the timer. The protocol is event-driven, and the main steps are as follows:

[0046] The present invention applies the potential energy field theory to design an attribute-related data aggregation protocol ADADR supported by dynamic routing, with the purpose of im...

Abstract

The invention discloses a data aggregation method with attribute correlation, comprising the steps of: S1, making a request for acquiring data; S2, if data packets come, executing step S2, and if a counter is started, executing step S6; S3, modifying the delay for modifying packet headers into the time for waiting local nodes, and placing the data packet into a DA queue; S4, ordering according to the delay size, if a timer is not started, starting the timer according to the minimum time delay, or, if the delay rate of the data packets newly monitored is less than the remaining time of the current timer, modifying the timer into the delay of the data packets newly monitored; S5, updating the size of the DA queue, and returning to the step S2; S6, taking out all the data packets which have the same application program with a queue head of the DA queue so as to carry out aggregated operation; and S7, based on a potential energy field model, determining a data packet of next-hop address for transmitting aggregated data packets. The method can adapt to various applications, and according to the method, the aggregation degree of the data packets containing related information is improved, and energy validity and expandability are achieved.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks (WSN), in particular to an attribute-related data aggregation method supported by dynamic routing. Background technique [0002] In the past ten years, wireless sensor networks have developed vigorously, which can be conveniently and quickly deployed in various environments to form networks independently and collect information. For example, environmental monitoring, intrusive monitoring, accident monitoring, etc. However, energy resources in wireless sensor networks are very limited, and it is difficult to be supplemented in time. Since the nodes in the wireless sensor network are usually relatively dense, the raw data collected by the nodes has a high degree of redundancy. The data aggregation protocol can compress the collected data on the intermediate nodes, thereby reducing the communication volume, saving energy and prolonging the life of the wireless sensor network. The ...
