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.

Due to various advantages of multipath routing over single path routing, multipath routing is considered as a suitable solution to guarantee the desired level of QoS in WMSNs. Many multipath geographic routing protocols have been proposed to satisfy multimedia QoS requirements in WMSNs. Moreover, disjoint multipath routing protocols can achieve bandwidth optimization and high reliability than multipath routing protocols. A large number of research works focuses on routing data through multiple disjoint paths in WMSNs. In this section, we present and discuss the most famous routing protocols designed for WMSNs in the literature.
