Embodiment Construction

[0033] Such as figure 1 As shown in FIG. 2 , it is a schematic diagram of an organizational structure of a congestion control method for a wireless multimedia sensor network. A congestion control method for a wireless multimedia sensor network described in the present invention revolves around one cache queue, a set of cache queue management mechanism, and two congestion control strategies.

[0034] The role of the cache queue is to receive and cache local data packets and data packets that need to be forwarded in the network. When a data packet arrives, the data packet carries the priority information of the data packet. If the priority is high, a correspondingly smaller discard probability is assigned, and if the priority is low, a larger discard probability is assigned.

[0035] In this embodiment, the discarding probability is assigned according to the following formula, where A is a constant, which can be set differently to meet different requirements, where A=1 is take...

Abstract

A congestion control method in a wireless multimedia sensor network relates to wireless network communication technology and is used for coping with network congestion in the wireless multimedia sensor network. The invention revolves around two congestion control strategies of node cache queue and data priority. First, a priority-based queue management mechanism is adopted for the cache queue of the node; the utilization rate and priority ratio are calculated according to the queue management mechanism of the present invention, and congestion detection is performed; then, by monitoring the congestion degree of the sub-node, the allocation of the sub-node is dynamically adjusted Adaptive sending rate; finally use the congestion flag, congestion processing flag and good state flag to make node marks, so as to select the backup route. The above congestion control method in the wireless multimedia sensor network is suitable for high-speed wireless sensor networks, and also suitable for wireless sensor networks with different priority requirements for services. The congestion control method in the wireless multimedia sensor network can improve network throughput and reduce network packet loss, has a good effect on congestion control, and is low in cost and easy to implement.

Description

technical field [0001] The invention relates to wireless sensor network communication technology, in particular to a congestion control method in wireless multimedia sensor network communication. Background technique [0002] With the continuous development and intersection of wireless communication, computer network and multimedia technology, wireless sensor network has been developed explosively. However, as the demand increases, the wireless sensor network needs to meet the needs of detecting more environmental parameter information. Wireless multimedia sensor networks are used in more and more detection and monitoring applications. Network congestion often occurs when the network is used for event monitoring. This causes problems such as a decrease in the overall throughput of the network, a shortened life cycle, and an increase in network energy consumption. [0003] Therefore, it can be seen from the above problems that it is necessary to propose a congestion contro...
