Research on Improved Capacity Algorithm of Wireless Sensor Network Based on QoS Fusion Technology
Providing high-quality service guarantee(QoS)has become a focal point of wireless sensor network research while ensuring network capacity is not compromised.By integrating the QoS parameter information of the network layer with the classical network ca-pacity model proposed by Gupta and Kumar,a cross-layer network capacity calculation strategy is then designed,which combines physi-cal and network layer characteristics.Firstly,a mathematical model of the Grover node state is constructed,describing QoS parameters such as network latency and node energy consumption.Then,D-S evidence theory is used to integrate QoS information to calculate the probability of network links.Finally,traditional formulas are modified and algorithms are developed for the capacity of multi-layer net-works.To validate the multi-layer network capacity algorithm,a simulation environment is constructed and the proposed algorithm is compared with the classical network capacity algorithm.The results show that the multi-layer network capability algorithm is more stable and reliable.
