Wenyin Yang · Jisuanji gongcheng · 2012
Based on Baidu system,the accurate localization/position technology is discussed about how to use it to design a geography position routing algorithm.By using greedy policy and geography position information,a new QoS-supported routing algorithm is designed for Wireless Multimedia Sensor Networks(WMSNs).As the main novel point,the algorithm guarantees an end-to-end delay upper bound for real-time communication inspired from SPEED firstly.Then a cost function is introduced to provide QoS support and balance the energy,lifetime,and the bandwidth performance.The soft/hard delay and others QoS parameters of the algorithm are analyzed in theory,and results show that the algorithm can provide more QoS supports for multimedia communication in WMSNs.
