Network Environments

This research aims at describing a method to subjectively measure specific parameters in a wired or wireless network environment using the Simple Network Management Protocols for the purpose of improving Reliability, Maintainability, and Availability of the network devices. This is of importance in cases where the network is in remote or hard to access locations such as space, defense, or polar applications. Furthermore, the results can be used for troubleshooting and/or failure prediction of the network devices. Applications of health monitoring and prediction in network environments are expanding as are the networks.

CERN is using an increasing number of DNS based load balanced aliases (currently over 700). This article explains the Go based concurrent implementation of the Load Balancing Service, both the client (lbclient) and the server (lbd). The article describes how it is being progressively deployed using Puppet and how concurrency greatly improves scalability, ultimately allowing a single master-slave couple of Openstack virtual machines to server all the aliases. It explains the new implementation of the lbclient, which, among other things, allows to incorporate Collectd metrics to determine the status of the node and takes advantage of the Go language concurrency features to reduce the real time needed for checking the status of the node. The article explains that the LBD server acts as an arbiter getting feedback on load and health from the backend nodes using snmp (Simple Network Management Protocol) to decide which IP addresses the LB alias will present. While this architecture has been used since long at CERN for DNS based aliases, the LBD code is generic enough to drive other load balancers. A proof of concept using HAProxy to provide adaptive responses to load and health monitoring has been implemented.

Wireless security is the prevention of unauthorized access to computers using wireless networks .The trends in wireless networks over the last few years is same as growth of internet. Wireless networks have reduced the human intervention for accessing data at various sites .It is achieved by replacing wired infrastructure with wireless infrastructure. Some of the key challenges in wireless networks are Signal weakening, movement, increase data rate, minimizing size and cost, security of user and QoS (Quality of service) parameters... The goal of this paper is to minimize challenges that are in way of our understanding of wireless network and wireless network performance.

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.

Proses monitoring jaringan access point terkadang membuat penyedia layanan harus selalu mendatangi titik access point untuk melakukan controlling. Tidak akan menjadi masalah apabila titik layanan access point hanya 1, namun jika dalam sekala yang cukup besar maka hal ini tentu akan menyita waktu cukup banyak. belum lagi administrator juga harus selalu mematikan dan menghidupkan perangkat guna mereset data cache nya setiap minggu. Untuk memecahkan masalah tersebut usaha yang dilakukan adalah dengan membangun sistem monitor access point menggunakan protokol sederhana yaitu dengan Simple Network Management Protocol(SNMP). Sistem monitoring jaringan access point menggunakan protokol SNMP merupakan sebuah rancangan sistem yang dapat membantu penyedia layanan access internet untuk memonitor kondisi access point di beberapa titik. Dengan adanya system monitoring ini penyedia layanan dapat melakukan controling dan monitoring jaringan berskala cukup besar tanpa harus mendatangi titik hotspot nya satu persatu.  Hasil pengujian dari sistem monitoring jaringan access point menggunakan Simple Network Management Protocol(SNMP) dapat disimpulkan bahwa sistem berjalan dengan hasil yang cukup baik dan sesuai harapan. pengujian terhadap progam juga dilakukan melalui beberapa peramban yang umum seperti  Mozilla Firefox, Microsoft Edge dan Google Chrome. Pengujian sistem juga dilakukan pada beberapa sistem operasi, yaitu windows, linux serta Android
