摘要
在无线多媒体传感器网络路由协议设计中,针对如何满足QoS传输需求并尽可能提高能量效率的问题,提出一种分簇结构的实时路由协议CBRP。将地理位置路由和非均匀的虚拟网格分簇技术有效地结合,动态调整数据包在簇头组成的骨干网络中的传输速率。仿真实验结果表明,该路由协议满足实时性、可靠性等质量域的QoS需求,能有效延长网络的生命周期。
In the design of routing protocol for Wireless Multimedia Sensor Networks(WMSNs), aiming at how to meet QoS transmission requirements as well as to improve the energy efficiency at the same time, an efficient routing protocol called Cluster-based Real-time Routing Protocol(CBRP) is proposed. CBRP can effectively integrate the geographic forwarding mechanism with uneven virtual grid-based clustering routing protocol and dynamically adjust the data packets transmission rate. Simulation results show that CBRP meets the requirement of QoS in real-time and reliability domains and can prolong the network life cycle.
