“…They propose two heuristic algorithms based on the steepest descent approach to solve the optimization problem. Aijaz et al [72] further extend [71] by introducing the notion of statistical QoS (i.e., probability of exceeding a specific delay threshold) and solve the optimization problem with canonical duality theory (CDT).…”

A huge increase of machines attached to wireless networks is expected in the next few years. A large part of these machines will be covered by some wireless wide area networks. The arrival of cellular M2M (machine-to-machine) communication poses new requirements due to its specific characteristics. For most of the cellular M2M applications, the essential requirement is low energy consumption level or high energy efficiency. This survey provides a global view of the network technologies previewed for cellular M2M. In this survey, we study the existing classifications of M2M applications according to different criteria in the literature. The comparison of traffic characteristics between M2M and human-to-human is also proposed. Quality of service (QoS) requirements for typical M2M applications are resumed. The advance of reference M2M network architectures proposed by the Standard Development Organization (SDO) is investigated. We identify two possible effort directions to improve the energy efficiency for cellular M2M. The first one is to evolve the current existing 3rd Generation Partnership Project (3GPP) Consortium cellular networks to effectively support MTC (Machine Type Communication). The other direction is to design M2M-dedicated networks from scratch, which are often called low-power wide-area (LPWA) networks. We review, compare and categorize the proposals related to energy issues of cellular M2M mainly over the period 2011-2015 for the first direction. We introduce the development of LPWA networks for the other research directions. We highlight that the cooperative relaying, the design of energy-efficient signaling and operation, the new radio resource allocation schemes, and the energy-efficient random access procedure are the main points of improvement. It is important to jointly use the aforementioned approaches, for example, joint design of random access control and radio resource allocation, to seek for a trade-off between energy efficiency and other system performances.

Abstract-In this paper, we conduct theoretical analysis and numerical simulation on the sensor network spectrum detection technology based on Internet of Things. In the field of Internet of things, information service system as a means of information, intellectualized, is an important research direction. In structure, Internet information service system is mainly composed of persistent database. Wireless sensor network foot a composed of a set of information collection, processing, and wireless transmission in the integration of wireless self-organizing network composed of micro sensor nodes. Sensor nodes structure will be designed according to different application scenarios, the structure of the wireless sensor network node is used to describe the different periods and different types of sensor nodes. If the realization of cognitive radio technology in wireless sensor network, not only can alleviate the congestion of public frequency band, and reduce the work frequency of the wireless sensor network also makes the node after single jump coverage is wide and change.

“…The authors in [11] have proposed a delay QoS provision algorithm, which evolved an effective capacity model to capture the effect of channel fading on the queuing behavior of the link in wireless OFDM networks. The authors in [12] have investigated the resource allocation scheme for the uplink of the LTE network under statistical delay QoS guarantees. However, the previous works about resource allocation under statistical delay guarantees in RF-OFDM systems adopted the centralized scheme and required a coordinator with powerful functionality, which conflicts with the low-complexity design idea of coordinator in local area networks.…”

“…Although gradient-based approaches have been proposed to solve the convex optimization problem, these schemes show many defects [12] such as oscillatory behavior, sensitivity to choice of initial values, etc. In our research, we target to support heterogeneous statistical delay QoS constraints, which inevitably aggravate the oscillatory behavior of gradient-based techniques.…”

In this paper, we explore a low-complex bandwidth allocation (BA) scheme with multi-level service guarantees in VLC-OFDM systems. Effective capacity theory, which evaluates wireless channel capacity from a novel view, is utilized to model the system capacity under delay QoS constraints of the link layer. Since intensity modulation of light is used in the system, problems caused by frequency selectivity can be neglected. Then, the BA problem can be formulated as an integer programming problem and it is further relaxed and transformed into a concave one. Lagrangian formulation is used to reformulate the concave problem. Considering the inefficiency of traditional gradient-based schemes and the demand for distributed implementation in local area networks, we localize the global parameters and propose a quasi-distributed quadratic allocation algorithm to provide two-level service guarantees, the first level is QoS oriented, and the second level is QoE oriented. Simulations have shown the efficient performance of the proposed algorithm. The users with more stringent QoS requirements require more subcarriers to guarantee their statistical delay QoS requirements. We also analyze the effect of subcarrier granularity on the aggregate effective capacity via simulations.
