Energy consumption efficiency during resource allocation is crucial for large scale networks. The evolution of Space Division Multiplexing Elastic Optical Networks (SDM-EONs) has presented tremendous spatial dimensions over single-mode networks to cope with the transmission of large traffic volumes, during peak load of the fluctuating traffic. However, due to large capacity transmission rates, the resource allocation challenges have led to incremental energy consumption. This is due to the impact of crosstalk (XT), which occurs between active adjacent cores, during core switching, and increasing service disruptions caused by rampant link failures. To address the above issues, this paper proposes a Distance-adaptive Energy-aware Resource Allocation (DERA) algorithm using a survival multipath scheme. The DERA algorithm implements the concept of the survival multipath scheme with Spectrum Compactness (SC) to minimize the impact of XT in SDM-EONs, during resource allocation. The objective is to improve spectral efficiency to save energy consumption, during peak load of the fluctuating traffic. During Routing, Modulation, Spectrum, and Core Allocation (RMSCA), the DERA algorithm can efficiently allocate resources in a survival multipath scheme. The performance of the DERA-RMSCA is compared with the two Multipath Protection (MPP) schemes, PRIME-RMSCA, and CMDE-RMSCA. The results demonstrate that DERA-RMSCA can achieve a better performance compared with PRIME-RMSCA, and CMDE-RMSCA.
