In this paper, we have proposed two energy-efficient heuristics: (i) CMDE-RSCA (crosstalk-aware), and (ii) FMDE-RSCA (fragmentation-aware) to address the issues of inter-core crosstalk, and fragmentation within the core respectively- to ensure quality transmission of the optical signal for dynamic traffic in space division multiplexing elastic optical network (SDM-EON), while maintaining survivability of the network against single link failure. These heuristics based on multipath based survivability are compared with three existing survivable approaches based on p-cycles and shared path in terms of bandwidth blocking, energy consumption, crosstalk, and fragmentation. Both these algorithms outperform all three existing heuristics in terms of all parameters. In between CMDE-RSCA and FMDE-RSCA, CMDE-RSCA leads to consume lesser energy, whereas FMDE-RSCA produces lesser bandwidth blocking.
