Problems solved by technology
Video communication has a large demand for bandwidth, but the network topology of the wireless ad hoc network may change in real time as users move, resulting in changes in the network transmission bandwidth, or even drastic changes
The existing wireless ad hoc network video communication technology cannot judge whether the nodes have high bandwidth conditions in real time, so it cannot provide video communication services effectively and stably

Embodiment Construction
[0052] Such as Figure 1-6 As shown in one of them, the present invention discloses a wireless ad hoc network video communication method, which includes the following steps:
[0053] Step 1. Configure an editable logical identification number for each communication terminal. The logical identification number is unique and serves as the calling number and called number for video communication; further, the logical identification number in step 1 is a fixed number of digits Arabic numerals. For example, 001, 020, 980, the logical identification number can be edited, and used as the calling number and called number of video communication. In a wireless ad hoc network, the logical identification number of each terminal is unique and cannot be the same as other terminals.
[0054] Step 2, such as figure 1 As shown in , set the minimum speed R required for video communication, and the terminal connectable measurement period is T c The value of the terminal can communicate and me...

The invention discloses a wireless ad hoc network video communication method and a terminal thereof, which utilize a high-bandwidth wireless ad hoc network and a mobile terminal thereof to carry out mobile video communication. In the wireless ad hoc network, the terminal A searches the optimal path of the terminal B according to the ad hoc network routing protocol, and establishes a video communication connection link through each intermediate forwarding terminal of the wireless ad hoc network after judging that the network bandwidth from the terminal A to the terminal B meets the video communication requirement. Video communication service can be carried out without deploying communication facilities with long construction period, such as a mobile base station, a backhaul network and a core network in advance, and the method is suitable for emergency communication, mountain communication, water / sea communication and video communication in areas where various mobile communication networks are difficult to deploy.
Description
technical field [0001] The invention relates to the field of ad hoc networks, in particular to a wireless ad hoc network video communication method and a terminal thereof. Background technique [0002] The highly flexible wireless ad hoc network not only supports point-to-point, point-to-multipoint, but also multipoint-to-multipoint, so it becomes an ideal wireless communication method in applications such as mobile video surveillance, command and control, or mobile robots. Wireless ad hoc networks generally have the characteristics of limited transmission bandwidth, high bit error rate, and frequent link changes, while multimedia data transmission, especially video stream transmission, has high requirements for bandwidth and is sensitive to delay, packet loss, and bit errors. The video communication problem of ad hoc network not only needs to make full use of its limited resources according to the communication characteristics of wireless ad hoc network, but also needs to d...
