In the design of routing algorithm for wireless multimedia sensor networks, aiming at how to meet QoS requirements as well as to improve the energy efficiency, an efficient Optimal Number of Clusters Algorithm (ONCA) was proposed. ONCA divides network region into uneven virtual grids based on the optimal number of clusters. ONCA selects and prioritizes the cluster-head and forwarding candidate set in an efficient manner, which considers the remaining energy of nodes. In the stage of data transmission, packets transmission rate can be optimized dynamically. Simulation results show that ONCA meets the requirement of QoS in real-time and reliability domains and can extend the network life cycle.
