abstract = {Dynamic dual-hop relaying network topologies that enable access to end-users through intermediate individual and commercial, static as well as moving, infrastructures are expected to become fundamental pillars of the sixth-generation wireless systems. Their main requirement is to ensure end-users information privacy. Motivated by this, the current contribution focuses on introducing a dual-hop blockchain radio access network (DH-BRAN) topology for dynamic coverage expansion. To analyze the performance of this topology, we present the theoretical framework that captures its characteristics. Building upon it, the DH-BRAN performance, in terms of latency and waiting probability, is quantified. Our results reveal that DR-BRAN can be employed in several realistic use-cases and that there exists a trade-off between latency and security.},

abstract = {Machine-to-machine (M2M) communications have emerged as a cost-effective, flexible and efficient solution of facilitating the penetration of independent 'things' and machines in local networks and systems. the latest releases of long-term evolution (LTE) such as LTE-Advanced (LTE-A) are being transformed to support the migration of M2M devices to end terminals. 3GPP supports the definition of technical requirements and functional specifications that allows the adapting of existing technologies to support machine type communications (MTC) and the optimization of the design of advanced standards (e.g., LTE-A) for efficient data delivery. According to ETSI M2M architecture three types of MTC access methods are supported, the direct access, the gateway access and the coordinator access. An MTC can access an evolved NodeB (eNB) with or without relay nodes. Hence coverage and connectivity issues appear on designing and deploying MTC architectures. This work is focused on studying and analyzing the probability of having at least k machine devices connected in modern cellular network, where the deployedM2Mdevices are directly or indirectly connected to the eNB node.e provided analytic framework is verified by simulation results that indicate suitable deployment conditions in specific MTC scenarios. © 2017 EAI.},
