Problems solved by technology

Due to the mobility of the mobile sink node, this method leads to a large control overhead, which affects the performance of the network; 2. The mobile sink node only broadcasts the status update information to the sensor nodes within one hop range of itself, and then these sensor nodes Then broadcast the control message to the whole network to inform itself that there is a mobile sink passing within the range of one hop, which also leads to a large control packet overhead

Embodiment Construction

[0012] Such as figure 1 and figure 2 , the present invention is based on the following assumptions: (1) All sensor nodes in the network are fixed.

[0013] (2) The number of fixed sink nodes and mobile sink nodes can be one or more.

[0014] (3) The deployment of fixed sink nodes can be random, or it can be deployed in a strip sensor network according to a certain optimization method.

[0015] (5) The mobile Sink node can adopt any mobile method.

[0016] (5) The mobile sink node periodically broadcasts Beacon messages to announce its existence as a mobile sink to the wireless sensor network.

[0017] The present invention has the following requirements: each data packet carries the following option (option), namely: Distance_to_MobileSink, to record the distance (in hops) between the current sensor node and a certain mobile sink. When Distance_to_MobileSink==1, it means that the current sensor node has a mobile sink as its neighbor node. If in the system design, the max...

Abstract

The invention relates to a simple network data collecting method of a mobile wireless sensor, which belongs to the technical field of the network data of a wireless sensor. The invention is characterized in that a mobile Sink node only broadcasts the self existence to the wireless sensor node within one-hop range in the moving process, other nodes except the wireless sensor node within the one-hop range of the mobile Sink node judge the option Distance_to_Mobile Sink in a packet to know whether the packet can reach a certain Sink node via a neighbor thereof or not via monitoring the packet of neighbor nodes, and the distance is smaller than the distance between the node and the nearest fixed Sink node thereof, so the broadcasting features of the wireless network are fully utilized, the expense for acquiring a control packet of the existence information of the current moving Sink node is greatly reduced, and simultaneously, the grouping transmission efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks. Specifically, it relates to an efficient and scalable data collection protocol for mobile wireless sensor networks. . Background technique [0002] Fixed Sink nodes and mobile Sink nodes coexist in wireless sensor networks based on mixed Sink (convergence) nodes. The existence of fixed Sink nodes ensures the reliability of data collection. Mobile Sink nodes are added to the wireless sensor network as a supplement to fixed Sink nodes. Reduce the energy overhead and transmission delay caused by long-distance multi-hop transmission from wireless sensor nodes to fixed sink nodes, and reduce the unbalanced energy consumption caused by hot spots, while improving the success rate of data transmission, thereby extending the network life, improving the quality of service of the entire wireless sensor network. [0003] At present, in the existing wireless sensor network data collection ...
