Wireless Sensor Network has been recognized as an attractive candidate among the telecommunication, meteorology, and sensor industries for the last few years owing to its wide range of applications, including environmental- and industrial-monitoring. In this paper, the authors propose an Energy Balanced Multi-hop Routing Scheme (EBMRS) at both the inter- and intra-clustering level to discover the optimal route to the Base Station (BS) for maximizing energy efficiency. It selects the required number of sensor nodes as Cluster-Heads (CHs) based on their Probability of Selection (PS) metrics like the residual energy, the number of hop-counts, and the distance to the BS. Inside inter-cluster communication, each sensor node decreases their energy consumption by using nearest intermediate sensor node to communicate with the CH. During intra-cluster communication, CHs adopt multi-hop approach to transmit the aggregated data to the BS by finding a suitable CH that locates on the way to the BS. Moreover, to avoid unbalance cluster-formation, EBMRS ensure that the CHs locate at a minimum distance from each other. The outcomes report an improvement of a minimum of 40% in the network’s lifetime of the demonstrated WSN network employed with the proposed EBMRS strategy in distinction with the existing energy-efficient routing approaches.

由于近几年来无线传感器网络的广泛应用，包括环境监测和工业监测，无线传感器网络已被公认为在电信，气象和传感器行业中有吸引力的候选者。在本文中，作者提出了一种在集群间和集群内级别的能量平衡多跳路由方案（EBMRS），以发现通往基站（BS）的最佳路由，以最大程度地提高能效。它根据传感器的选择概率（PS）度量标准（例如剩余能量，跳数的数量和到BS的距离）选择所需数量的传感器节点作为簇头（CH）。在集群间通信中，每个传感器节点通过使用最近的中间传感器节点与CH进行通信，从而降低了能耗。在集群内通信期间，CH通过找到位于通往BS的途中的合适CH，采用多跳方法将聚合数据传输到BS。此外，为了避免集群形成不平衡，EBRMS确保CH相互之间的距离最小。结果表明，与现有的节能路由方法不同，与拟议的EBMRS策略一起使用的WSN网络在网络生命周期中至少提高了40％。
