Embodiment Construction

[0075] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings (taking mobile social networking as an example in the field of emergency search and rescue).

[0076] Assuming that an earthquake occurs in a certain area, a group of search and rescue personnel enter the area to carry out search and rescue work, and each search and rescue personnel carries a mobile device (called a node).

[0077] At 12:00 on April 4th, node A (node ​​A's ID is 1) found that a seriously injured patient was buried underground, and this message (data number is 01, message content is EEEE, and the life cycle of the message is 2 hours) sent to the command center (the ID of the command center is 9) to request support, the incident is very urgent, at this time the node selects the TMP-E mode (as shown in Figure 1). Node B (the ID of Node B is 2) is a node within the communication range of Node A. The remaining energy of Node B is 35 (u...

Abstract

The present invention provides a data handover method based on mobility profiles, which introduces and utilizes the mobile behavior of nodes in mobile opportunistic networks in view of the regularity of mobile behavior in mobile social networks and the limited power and storage space of mobile devices To get the mobile summary that can represent the mobile behavior of the node, the mobile summary is combined with other energy and space parameters, and different handover modes are adopted for the urgency of data forwarding, which increases the packet delivery rate, reduces the number of forwarding times, and avoids In order to prevent uneven load; the data is classified and processed to meet the needs of practical applications.

Description

technical field [0001] The invention relates to a data transfer method based on a mobility profile, which belongs to the intersection field of mobile social network and opportunistic network. Background technique [0002] Social network provides a virtual social platform for people to communicate, participate and collaborate with each other. With the rapid development of wireless communication technology and the popularization of smart mobile terminals, the traditional online social platform has shifted from PC to mobile terminal, and the interaction mode has expanded from online to offline, forming a mobile social network (MSN). According to the "2014 China Mobile Social User Demand and Behavior Research Report" released by Nielsen, a world-renowned market research company, as of June 2014, the number of mobile Internet users in my country reached 530 million, accounting for 83.4% of the total number of Internet users. One of the main applications on the mobile side. Smartp...
