Network Manager

The use of industrial wireless networks has been growing continuously and it hasbecome an alternative to wired networks. One of the main elements of an industrial wireless network is the network manager, this component is responsible for tasks related to the network construction and maintenance. This work presents the development of a network manager compatible with the WirelessHART protocol, but also customizable, where it is possible to make modifications in order to carry out studies with this protocol. Case studies are presented where the developed tool was used for studies related to communications scheduling, adaptive channel mapping and fast data collection, thus proving the efficiency of the proposed manager.

Management of wireless networks as well as wired networks by using software-defined networking (SDN) has been highlighted continually. However, control features of a wireless network differ from those of a wired network in several aspects. In this study, we identify the various inefficient points when controlling and managing wireless networks by using SDN and propose SDN-based control architecture called Proxcon to resolve these problems. Proxcon introduces the concept of a proxy SDN controller (PSC) for the wireless network control, and the PSC entrusted with the role of a main controller performs control operations and provides the latest network state for a network administrator. To address the control inefficiency, Proxcon supports offloaded SDN operations for controlling wireless networks by utilizing the PSC, such as local control by each PSC, hybrid control utilizing the PSC and the main controller, and locally cooperative control utilizing the PSCs. The proposed architecture and the newly supported control operations can enhance scalability and response time when the logically centralized control plane responds to the various wireless network events. Through actual experiments, we verified that the proposed architecture could address the various control issues such as scalability, response time, and control overhead.

Network is a technology used to connect computers and devices together. They allow people the ability to move easily and stay in touch while roaming the Internet in the coverage area. This increases efficiency by allowing data entry and access to the site. Comparing wireless networks wired networks in terms of cost, we find that wired networks are more expensive due to the cost of the network connections of electricity and running and add computers and change their positions to suit the network supply.   As a result, the use of widespread wireless networks. But there are security gaps in these networks may cause problems for users Security holes intended problem or weakness in the wireless network system may make it easier for hackers to penetrate and steal sensitive data and causing material losses to individuals and companies. Knowing security holes and contributes significantly to the wireless network is immune from attempts to infiltrate and penetration design Keywords—Protocol: Language is between computers connected via the network, in order to exchange information. If we define the language of the Protocol technology, we say that a formal description of the bodies messages and rules that must be followed on two computers to exchange those messages.

Management Conflicts

The communication protocols used in industrial wireless networks are designed to meet requirements of security and reliability in communications. These requirements are guaranteed by techniques like message enciphering and radio frequency interference avoidance. The WirelessHART protocol was the first one developed specifically to meet the needs of industrial applications. WirelessHART networks use centralized control where one element, the network manager, is responsible for configuring, creating and maintaining the network. This feature increases reliability as management conflicts will not occur, but the rout of communications between network manager and field devices may need several hops on the network due to the mesh topology employed in the protocol. Procedures such as joining new devices require the exchange of a series of commands with the network manager, which takes a large period of time to be executed. This paper presents a technique designed for mobile devices aiming the reduction of time needed for the publishing service. The proposed technique favors the use of mobile devices with strict time constraints under the range covered by the wireless network and precedes the study of an efficient handover process. The results present a time comparison between the standard and proposed data collection.

Planning Capacity

Abstract In densely populated urban centers, planning optimized capacity for the fifth-generation (5G) and beyond wireless networks is a challenging task. In this paper, we propose a mathematical framework for the planning capacity of a 5G and beyond wireless networks. We considered a single-hop wireless network consists of base stations (BSs), relay stations (RSs), and user equipment (UEs). Wireless network planning (WNP) should decide the placement of BSs and RSs to the candidate sites and decide the possible connections among them and their further connections to UEs. The objective of the planning is to minimize the hardware and operational cost while planning capacity of a 5G and beyond wireless networks. The formulated WNP is an integer programming problem. Finding an optimal solution by using exhaustive search is not practical due to the demand for high computing resources. As a practical approach, a new population-based meta-heuristic algorithm is proposed to find a high-quality solution. The proposed discrete fireworks algorithm (DFWA) uses an ensemble of local search methods: insert, swap, and interchange. The performance of the proposed DFWA is compared against the low-complexity biogeography-based optimization (LC-BBO), the discrete artificial bee colony (DABC), and the genetic algorithm (GA). Simulation results and statistical tests demonstrate that the proposed algorithm can comparatively find good-quality solutions with moderate computing resources.
