In Wireless Multimedia Sensor Networks (WMSNs), nodes capable of retrieving video, audio, images, and small scale sensor data, tend to generate immense traffic of various types. The energy-efficient transmission of such a vast amount of heterogeneous multimedia content while simultaneously ensuring the quality of service and optimal energy consumption is indispensable. Therefore, we propose a Power-Efficient Wireless Multimedia of Things (PE-WMoT), a robust and energy-efficient cluster-based mechanism to improve the overall lifetime of WMSNs. In a PE-WMoT, nodes declare themselves Cluster Heads (CHs) based on available resources. Once cluster formation and CH declaration processes are completed, the Sub-Cluster (SC) formation process triggers, in which application base nodes within close vicinity of each other organize themselves under the administration of a Sub-Cluster Head (SCH). The SCH gathers data from member nodes, removes redundancies, and forwards miniaturized data to its respective CH. PE-WMoT adopts a fuzzy-based technique named the analytical hierarchical process, which enables CHs to select an optimal SCH among available SCs. A PE-WMoT also devises a robust scheduling mechanism between CH, SCH, and child nodes to enable collision-free data transmission. Simulation results revealed that a PE-WMoT significantly reduces the number of redundant packet transmissions, improves energy consumption of the network, and effectively increases network throughput.
