QoS routing protocol for WMSNs based on differentiated services
|
Abstract:
Aiming at large data transmission volume and different QoS requirements for various traffic transmission levels in wireless multimedia sensor networks, introduced a data fusion of differentiated services QoS routing algorithm (DF-DSQR). In this algorithm, established two gradient for real-time business and best-effort business during the interest flooding, used the priority queue model when transmited the two businesses and data fusion forwarding mechanisms, provided the QoS path for BE business and RT business. The Simulation results show that the routing can guarantee low latency requirements of real-time business, ensure QoS requirements for the best-effort business, balance the energy consumption and prolong the network lifetime.
