The mining process in blockchain requires solving a proof-of-work puzzle, which is resource expensive to implement in mobile devices due to the high computing power and energy needed. In this paper, we, for the first time, consider edge computing as an enabler for mobile blockchain. In particular, we study edge computing resource management and pricing to(More)
An important issue in Wireless Sensor Networks (WSNs) is to maximize the network lifetime while guaranteeing the desired coverage requirement. Recent studies have demonstrated that using rechargeable sensor nodes with energy harvesting capability has a great potential to extend the network lifetime. However, due to the high cost of rechargeable nodes,(More)
This paper studies the three-dimensional coverage of an underwater wireless sensor network (UWSN) consisting of anchored nodes. As anchored nodes are first randomly deployed on the ocean surface and can only move in the z-axis direction, we propose a two-stage node selection and sinking scheme to maximize the network coverage. In the first stage, we adopt a(More)
