Abstract:

Wireless networks technology has broad prospects in today's society. With the increase in wireless network nodes, network latency has become an important problem to be solved. In order to provide quality of service (QoS) and increase throughput, we propose a model based on priority queuing delay of each packet by pre-setting priorities to distinguish their importance and timeliness, while each of the AP according to the priority queue is divided into three types, and the default priority packets into which transmission, thus effectively reducing the sender queuing delays. Simulation shows that compared to non-prioritized queue of nodes in the network, this program greatly reduces both the delay of a single node and the average delay across the network, thus a significantly improved overall network performance.
