QoSPMR: QoS-Aware and Priority-Based Multipath Routing Algorithm for WMSNs

摘要

A QoS-aware and priority-based multipath routing (QoSPMR) algorithm is proposed for WMSNs. The proposed algorithm comprehensively considers the categories and priorities of multimedia streams, the residual energy of nodes, the local link reliability between nodes, the local congestion status and the distance from the candidate next hop nodes to the sink. Simulation results show the QoSPMR algorithm is more effective than the TPGF algorithm.
