Multimedia applications in wireless multimedia sensor networks (WMSNs) demand a high level of quality of service (QoS) requirements. The multipath routing approach is considered as an effective solution to meet these requirements. However, the high-energy consumption in WMSNs is a critical concern for lifetime of network contains sensor nodes with limited battery. Many proposed works have designed multipath routing protocols to provide load balancing between discovered paths, although there is a trade-off between power efficiency and data delivery. This paper proposes a link quality and load balancing multipath geographic routing (LQLB-MGR) protocol for WMSNs. This protocol consists of two phases. The first phase is responsible to find multiple node-disjoint paths with high link quality and the second phase allows load balancing between the discovered paths based on nodal residual energy. Simulation results show that LQLB-MGR provides better performance compared to other protocols.
