Embodiment approach

[0042] figure 1 It is a schematic diagram of the scene of the present invention, and its specific implementation is as follows:

[0043] (1) Due to the limitation of geographical environment, figure 1 In the network scenario shown, each sensing area can only rely on mobile nodes moving randomly along a given route to deliver sensing data to the sink node. Opportunistic sensing networks run for a while [t 0 ,t τ ], network topology transformation such as figure 2 shown.

[0044] (2) Will figure 2 The relevant information is merged to obtain a Temporal Graph, such as image 3 shown. The time symbols (t 1 ,t 2 ,t 3 ) indicates the sequence relationship of link generation, which can reflect the accessibility (Sink node) of sensing data (generated by each sensing area). For example, although the perception area R3 has a "path" It leads to the Sink node, but the link R2→F2 is generated after the link F2→F1, so that the data can only be transmitted to F2, and the data ...

Abstract

The invention discloses a method for expressing the connectivity of an opportunistic sensor network by using the connectivity of the entire network. This method is suitable for practical application scenarios such as environmental monitoring and communication in remote mountainous areas. Due to the limitation of terrain, the sensor network is divided into multiple areas. The network connectivity in the area is good, but the areas are not connected to each other. Specific mobile nodes collect and transmit the sensing data generated by the region, thus forming an opportunistic sensor network with disconnected regions. The present invention firstly defines a key parameter reflecting network connectivity—the connectivity of the entire network according to the transmission characteristics of opportunistic sensor network perception data; then, according to the topology transformation characteristics of the network, regularly obtains snapshots of the entire network; then the obtained The snapshot set is converted into an ordered adjacency matrix set; finally, the connectivity of the entire network is calculated through the adjacency matrix set to represent the connectivity of the opportunistic sensor network. The invention fully considers the transmission characteristics of the opportunistic sensor network perception data, and uses the connectivity of the entire network to accurately reflect the connection status of the opportunistic sensor network.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a method for expressing the connectivity of an opportunistic sensor network by using the connectivity of the entire network. Background technique [0002] In Opportunistic Sensor Networks (OSN, Opportunistic Sensor Networks), mobile nodes move randomly or according to certain rules to achieve data collection in the target area. Compared with a large number of deployed static sensor networks, OSN achieves large-scale sensing at a lower cost, and has the basic characteristics of opportunistic networks (OppNet, Opportunistic Networks) and general delay tolerant networks (DTN, Delay Tolerant Networks), namely intermittent connections, frequent Fragmentation, high latency, etc. In practical application scenarios such as environmental monitoring and communication in remote mountainous areas, due to terrain constraints, the sensor network is divided into mult...
