Embodiment Construction

[0054] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0055] The present invention provides an opportunistic data transmission method based on multi-behavior locations. The method describes the multi-behavior attributes of mobile users, uses weights as the data forwarding basis for multi-behavior locations, and can effectively transmit data to users with multi-behavior locations. In the user group of attributes. The specific implementation process of this method is as follows: figure 1 shown. This method requires the support of a cloud server to store and calculate user data and perform real-time data interaction. User / cloud platform interaction model such as figure 2 shown.

[0056] The specific implementation steps are:

[0057] Step 1: Set the number of users as n and the number of locations as m, the time consumed by user i∈{1,…,n} at the behavior location j∈{1,…,m} is expressed as the number of time slices...

Abstract

The invention provides an opportunity-type data transmission method based on multiple behavior sites, aiming to solve the problem of incapability of accurately sending data to attribute users of the behavior sites. According to the method, the user performs site behavior registration on a cloud server, the cloud server stores a user / behavior site combined matrix, and a server updates the matrix timely and returns a newest time slice vector to the user. A source user starts a data forwarding process after applying data from the cloud server. In the process of data forwarding, a circuit is initiated and messages are transmitted to the attribute users of h different behavior sites, wherein the h refers to the number of the sites. In the progressive gradient increase stage of forwarding, the messages are forwarded to intention receivers of the behavior sites layer by layer. The data are sent to the intention receivers of all the surrounding behavior sites in a multicast mode. The data are forwarded to the users of the behavior sites by taking user behavior attribute weights as forwarding conditions, so that data transmission rate is improved effectively and energy consumption is lowered.

Description

technical field [0001] The invention proposes an opportunistic data transmission method based on multi-behavior locations, which belongs to the intersecting fields of opportunistic networks and social networks. Background technique [0002] At present, there are some shortcomings in traditional sensor networks: (1) A large number of sensing devices need to be manually pre-deployed, which is not only expensive, but also increases the complexity of the system with the expansion of scale. (2) Static deployment of sensing devices is generally not densely deployed, making the perception perspective single and unable to perceive objects in an all-round way. (3) Forwarding data according to the node ID is not suitable for highly dynamic mobile network scenarios, nor can it be applied to networks with specific interest preferences. [0003] With the development of technology, a large number of mobile smart devices with rich sensors have emerged. As a next-generation sensing technol...
