As mudanças de temperatura, salinidade e correntes oceânicas no ambiente subaquático têm efeitos adversos no alcance de comunicação dos sensores e fazem com que eles se tornem falhas temporárias. Esses sensores que se comportam temporariamente mal são chamados de nós burros. Neste artigo, é proposto um esquema de restabelecimento da conectividade com eficiência energética (EECR). Ele pode reconstruir a topologia de redes de sensores acústicos subaquáticos (UASNs) com a existência de nós burros. Devido à dinâmica do ambiente subaquático, a geração e recuperação de nós burros também mudam dinamicamente, resultando na interrupção intermitente da topologia da rede. Portanto, um modo de transmissão multibanda para nós burros é projetado primeiro. Ele garante que os dados atuais armazenados de nós burros possam ser enviados a tempo. Posteriormente, é desenhado um esquema de restabelecimento da conectividade dos subnós. A reconstrução da topologia é implementada de forma adaptativa, alterando o caminho de transmissão atual. Este esquema não precisa organizar os nós do sono com antecedência. Portanto, pode reduzir bastante as despesas com mensagens e o consumo de energia. Os resultados da simulação mostram que o método proposto apresenta melhor desempenho de rede nas mesmas condições que os algoritmos clássicos denominados LETC e A1. Além do mais, nosso método tem uma taxa de transferência de rede mais alta quando o comportamento burro dos nós tem uma duração mais curta.

Abstract: The changes of temperature, salinity and ocean current in underwater environment, have adverse effects on the communication range of sensors, and make them become temporary failure. These temporarily misbehaving sensors are called dumb nodes. In this paper, an energy-efficient connectivity re-establishment (EECR) scheme is proposed. It can reconstruct the topology of underwater acoustic sensor networks (UASNs) with the existing of dumb nodes. Due to the dynamic of underwater environment, the generation and recovery of dumb nodes also change dynamically, resulting in intermittent interruption of network topology. Therefore, a multi-band transmission mode for dumb nodes is designed firstly. It ensures that the current stored data of dumb nodes can be sent out in time. Subsequently, a connectivity re-establishment scheme of sub-nodes is designed. The topology reconstruction is adaptively implemented by changing the current transmission path. This scheme does't need to arrange the sleep nodes in advance. So it can reduce the message expenses and energy consumption greatly. Simulation results show that the proposed method has better network performance under the same conditions than the classical algorithms named LETC and A1. What's more, our method has a higher network throughput rate when the nodes' dumb behavior has a shorter duration.
