Abstract

The invention discloses a self-organization method of a sensor network and a mobile terminal system based on the same. According to the self-organization method of a sensor network, a sensor self-organization network can be formed by all nodes according to a multi-hop route protocol based on link prediction survival time, the node can be directly communicated with a node within a node communication range and communicated with a node not within the node communication range through transfer of other nodes in a multi-hop manner. The mobile terminal system comprises more than three terminals which form a sensor network by using the self-organization method of the sensor network. The system can obtain position, speed and motion direction information of other terminals through position acquisition; terminals with abnormal occurrence can inform the abnormal information of left terminals; and multi-hop voice and video two-direction transmission can be realized. The self-organization method ofthe sensor network and the mobile terminal system based on the same have the advantages of good performance, multiple functions and wide application prospect.

Description

technical field [0001] The invention relates to sensor network technology, in particular to a sensor network self-organization method and a multifunctional mobile terminal system. Background technique [0002] With the continuous development of information technology, people's research on sensor network continues to heat up. The essence of sensor network is a kind of Adhoc network. At present, most mobile communication systems are centralized and controlled (centered), and the operation of the network depends on the pre-deployed network infrastructure, such as cellular mobile communication systems and wireless local area networks. However, for some special occasions, such as: coordinated communication of troops on the battlefield, post-disaster rescue of earthquakes or sudden accidents, inter-vehicle communication networks, field scientific investigations, temporary meetings, etc., the communication in these occasions cannot rely on any pre-established network. facilities, ...
