Optimization of Congestion Avoidance and Multipath Routing in Wireless Sensor Networks with Node Addition and Reduction
摘要
Abstract
The increase or decrease of nodes in wireless sensor networks results in a network topology change,increasing the likelihood of random path selection and affecting transmission efficiency.Therefore,a congestion avoidance multipath routing optimization method for wireless sensor networks with node increase or decrease is proposed.The energy consumption of each node on the path is calculated based on the energy consumption calculation method of wireless sensor network nodes to determine whether node increase or decrease has occurred.A node increase/decrease function based on the changes in energy consumption after node increase/decrease is set,and the node increase/decrease function,node congestion prediction,and forwarding satisfaction are comprehensively considered to construct a multipath routing optimization objective function.The MPSO algorithm is used to solve the objective function and adjust the number of nodes in the candidate path,thus achieving congestion avoidance optimization in multipath routing.The simulation results show that when the number of paths is 40,the network congestion level remains below 0.4％,the node buffer queue utilization rate of this method remains above 98％,the highest network packet loss rate is 2.0％,the maximum power consumption of the node is 3.1 W,idicating that the efficiency of network node data transmission is improved.关键词
