基于北斗系统的QoS保障地理位置路由算法
QoS-supported Geography Position Routing Algorithm Based on Baidu System
摘要
Abstract
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.关键词
