The incorporation of cognitive radio (CR) and energy harvesting (EH) capabilities in wireless sensor networks enables spectrum and energy-efficient heterogeneous CR sensor networks (HCRSNs). The newâ€¦ (More)

In general, an element k of a ring R is said to be (von Neumann) regular if there is an x âˆˆ R such that k = kxk. Let n > 1 be an integer with prime factorization n = p1 1 Â· Â· Â· p Î½r r . An integer kâ€¦ (More)

In this paper, we study sustainable resource allocation for cloud radio access networks (CRANs) powered by hybrid energy supplies (HES). Specifically, the central unit (CU) in the CRANs distributesâ€¦ (More)

The contradiction between the limited capability of lightweight Internet-of-Things (IoT) devices and ever-increasing user demands is a fundamental and challenging problem in the era of IoT. One ofâ€¦ (More)

Block-stream as a service (BaaS) has been considered as a promising service provisioning model for lightweight devices, in which the server streams code blocks partitioned from an APP to devices inâ€¦ (More)

By equipping with the advanced smart meters and two-way communications infrastructure, smart grids, as a key component of future smart cities, are able to improve the energy efficiency and reduce theâ€¦ (More)

In this paper we consider a class of functions U of arithmetical functions which includeËœP (n)/n, whereËœP (n) := n p|n (2 âˆ’ 1 p). For any given U âˆˆ U, we obtain the asymptotic formula for nâ‰¤x U (n),â€¦ (More)

Let âˆ† 1 (x; Ï•) be the error term of the first Riesz means of the Rankin-Selberg zeta function. We study the higher power moments of âˆ† 1 (x; Ï•) and derive an asymptotic formula for 3-rd, 4-th and 5-thâ€¦ (More)
