A smart grid (SG) is an intelligent electricity network that integrates the actions of all users that are connected to it and make use of advanced information, control, and communication technologies in order to efficiently deliver sustainable, economic and secure electricity supplies [1]. The high-speed, bi-directional, real-time, and integrated communications system is the foundation of SG [2]. In addition to counting and pricing in smart metering, one of its most prominent requirements is to support users in smart energy utilization. Therefore, residential and enterprise consumers have to be enabled by the SG infrastructure to become aware of their energy consumption behavior.
Automated metering is one of the subsystems of SGs and plays

The communication infrastructure in SG must support the expected SG functional- ities and meet the performance requirements. As the infrastructure connects an enor- mous number of electric devices and manages the complicated device communications, it is constructed in a hierarchical architecture with interconnected individual subnet- works and each taking responsibility of separate geographical regions [7]. Some of the key communication networks in enabling SGs are long term evolution (LTE) and wireless sensor network (WSN). LTE is considered a strong candidate for handling SM communication as it provides ubiquitous wide area coverage, high availability and strong security [3]. The LTE network will provide faster and more accurate use, load and disruption information, which will help utility companies to plan and manage their resources. The WSN represents a good candidate to be adopted as the communication solution for the last mile connection in process monitoring and control applications [8]. Further, WSNs have been widely recognized as a promising technology that can en- hance various aspects of today’s electric power systems, including generation, delivery, and utilization, making them a vital component of the next-generation electric power system, the SG [7]. WSN solutions are based on standardized protocols. There are many different protocols for the upper
