Abstract (EN): Typical wireless multimedia sensor networks are composed of many randomly deployed nodes which can retrieve information from the monitored field and relay packets following a hop-by-hop communication model. The transmission of packets from source nodes to the destination may flow across multiple paths, each one comprised of a number of intermediate nodes. The simple existence of a sensing unit in intermediate nodes or the estimation of cameras' Field of View over a monitoring target may turn relevant some sensors that compose a particular available path. We propose two coverage-aware node-disjoint multipath selection algorithms to distribute multimedia traffic over the available paths considering the sensing relevance of the intermediate nodes, potentially prolonging the lifetime of more relevant sensors for the application monitoring tasks.
