HE Xiao, SHI Wei-ren, WANG Xiao-gang, et al. A DPSO-based QoS routing algorithm for wireless sensor networks[J]. 2012, 31(4): 123-126. DOI: 10.13873/j.1000-97872012.04.020.
Aiming at different QoS requirements in different services
a QoS routing algorithm based on discrete particle swarm optimization(DPSO-QR)for wireless sensor networks is proposed.In DPSO-QR
the routing establishment process is Abstracted as multi-objective optimization process.The propagation loss
time-delay
bandwidth and packet loss rate between the communication nodes are the optimization goals.The algorithm can provide network services which have different QoS requirements with optimized routing.The simulation results comparing with typical QoS routing algorithm show that DPSO-QR can effectively reduce the average end-to-end delay
