As redes de sensores sem fio alcançaram um papel de destaque no cenário atual das novas de tecnologias de comunicação, centradas em aplicações de Internet das Coisas e Cidades Inteligentes, sobretudo quando câmeras são utilizadas para obter dados visuais do ambiente monitorado. Nessas redes, questões de eficiência energética são centrais, uma vez que, frequentemente, sensores são alimentados por bateria. Para tanto, um correto e eficiente planejamento energético de redes de sensores sem fio é fundamental para diversas aplicações, levando à escolha mais apropriada dos sensores, dos protocolos de comunicação e das unidades de monitoramento. Visando dar suporte a estimativas de desempenho de redes de sensores visuais sem fio, permitindo análises teóricas sem necessitar da implantação física das redes, este artigo propõe um novo modelo matemático para estimativas de consumo de energia de sensores equipados com câmeras, permitindo importantes avaliações de desempenho antes da implantação da rede real. Além do modelo é apresentada uma nova ferramenta computacional, EnergyWVSN, desenvolvida para facilitar o uso prático do modelo proposto.References
