Design of WSN traffic forecasting system with delayed self-sensing

ABSTRACT

In order to achieve the load balancing between network nodes, improve the utilization of system resources and network throughput, and reduce network delay. Therefore, based on the Optimized Link State Routing (OLSR) protocol, this paper proposes an improved protocol of OLSR based on traffic load balancing and QoS. OLSR-TLB protocol takes the traffic load balancing and QoS into account. For real-time traffic, focus on the traffic load of the access point. If the access point traffic load is too high, it cannot be connected with the routing. However, for non-real-time traffic, QoS but not traffic load is considered, making routing decisions based on hop counts. In addition, the traffic service is divided into real-time traffic and non-real-time traffic. The former considers the real-time, making routing decisions based on traffic load, while the latter considers QoS, making routing decisions based on hop counts. Simulation results show that the proposed OLSR-TLB protocol can effectively improve the throughput and reduce the delay performance. Compared with the traditional OLSR protocol, the throughput of OLSR-TLB protocol is improved to 3.5Mbps, and the delay is reduced to 50 ms.
