A cooperative Internet of Things (IoT) for rural healthcare monitoring and control

Internet of Things (IoT) concept enables the possibility of information discovery about a tagged object or a tagged person by browsing an internet addresses or database entry that corresponds to a particular active RFID with sensing capability. It is a media for information retrieval from physical world to a digital world. With cooperative wireless communication, the wireless node entities can increase their effective quality of service (QoS) via cooperation. In developing countries the death rates due to lack of timely available medical treatments are quite high as compared to other developed countries. The majority of these deaths are preventable through quality care. This paper proposes a cooperative IoT approach for the better health monitoring and control of rural and poor human beings health parameters like blood pressure (BP), hemoglobin (HB), blood sugar, abnormal cellular growth in any part of the body, etc.

Cooperative opportunistic large array approach for cognitive radio networks

Cognitive Radio (CR) seems to be a promising solution to the radio spectrum congestion problem by opportunistic uses of the spectral holes to achieve efficient use of the frequency resource by allowing the coexistence of licensed (primary) and unlicensed (secondary) users in the same bandwidth. According to the cooperative wireless communication (CWC) concept the active nodes may increase their effective QoS via cooperation. For cognitive radio networks, sharing of primary users spectrum by secondary user is possible only when the QoS of the primary system is guaranteed. Cooperative diversity is a strong technique which can provide the maximum throughputs. Cooperative Opportunistic Large Array (OLA) algorithms can improve the reliability as well as the energy efficiency of the communication. Power and diversity gains can be exploited with the help of cooperative transmission in the cognitive radio. In this paper, the novel cooperative OLA approach for Cognitive Radio Networks (CRN) is proposed, which is proved to be energy efficient and scalable. With the help of OLAs, the cognitive network can be built without GPS.

Receiver Sensitivity in Opportunistic Cooperative Internet of Things (IoT)

In Cooperative communication, a source message is relayed through a locally connected network by means of cooperating network nodes. Recently, the cross layer cooperative schemes have been shown to offer multiple advantages over the single layer approaches. In distributed cooperation schemes, the cooperating nodes make transmission decisions based on the quality of the received signal, which is the only parameter available locally. Receiver sensitivity is the most important parameter of the physical layer and has a direct impact on the MAC layer. This paper proposes a novel cooperative approach for analysis of receiver sensitivity.

Reliable and Secure Cooperative Communication for Wireless Sensor Networks Making Use of Cooperative Jamming with Physical Layer Security

Interference is generally considered as the redundant and unwanted occurrence in wireless communication. This research work proposes a novel cooperative jamming mechanism for scalable networks like wireless sensor networks which makes use of friendly interference to confuse the eavesdropper and increase its uncertainty about the source message. The communication link is built with the help of Information theoretic source and channel coding mechanisms. The whole idea is to make use of normally inactive relay nodes in the selective Decode and Forward cooperative communication and let them work as cooperative jamming sources to increase the equivocation of the eavesdropper. In this work, eavesdropper’s equivocation is compared with the main channel in terms of mutual information and secrecy capacity.

SDN Control Plane Security in Cloud Computing Against DDoS Attack

In Software Defined Networking a Denial-of- Service (DoS) or Distributed Denial-of-Service (DDoS) attack is an attempt to make a machine or network resources unreachable for its particular users. so, the require for security of such network controller against attacks from within or outside a network is very more important. Although network devices in OpenFlow can also be targeted by attackers and so required a Defense mechanism to avoid problems in smooth packet forwarding attack. SDN Give the Functionality to Overcome DDoS Attack use Control plan and data plan. Also, they manage the network use SDN controller to monitor network. SDN network flexibility provides they interface OpenFlow and switches network by Mininet. That all are merge to single centralized control point.

Enhancement of spectral efficiency, coverage and channel capacity for wireless communication towards 5G

In this paper, we are trying to improve spectral efficiency, coverage, data capacity and channel capacity for 5G technology. Improvement in these parameters for 5G will make it more advanced, efficient and flexible. In order to achieve above parameters one can follow encoding technique based on Fastqz compression algorithm, then interleaving concept by using Prime interleaver. Afterwords, Trellis Coded Modulation with advanced technique of Extended Min-Sum algorithm (T-EMS), can be implemented to improve spectral efficiency followed by tunable polyphase filter.

Forthcoming Fifth Generation wireless network will be converged version of all the available wireless and wired networks including cognitive radio network, Wi-Fi, cellular, Wi-Max, WSN, IoT, Li-Fi, satellite communication and optical fiber network. Presently in the era of 4G, numbers of researchers have designed different antennas which can integrate maximum four services.

The antenna planed to be designed and optimized by making using of commercially available software-High Frequency Structure Simulator (HFSS).

Implementation of Costing Model for High Performance Computing as a Services on the Cloud Environment

Every enterprise is moving towards the cloud platform. High Performance Computing (HPC) is a necessity for many industries for their data analytics or huge computations tasks. All enterprises cannot afford supercomputers. Moving towards HPC systems on the cloud environment is costly for small scale industry. This paper focus on costing model for HPCaaS on the Cloud environment. So that small organization can afford to have their own HPC systems at the low costs. In this Paper authors propose and Implement a costing model and algorithms with respect to resource pool. Furthermore, the Authors Implement a simple calculation Tool and discuss one scenario based on proposed model and algorithms.

Computer vision for green and secure cooperative augmented reality in Next Generation Converged Wireless Networks

With the help of digital resources, self-description of smart objects causes some limitation into the input qualities because of the long established physical appearances. Also to realize the capability of objects to understand and recognize the data. If an uninstrumented surface is provided, the object should be able to sense gestures and touches upon the surface. To design an area for supporting whole body metaphors physical movements and position of entire body .Objects such as sensors, processors and radios are integrated invisibly into smart sensitive objects for user interaction. In this paper, we propose to rectify the excitation and response imbalance by augmentation of smart objects with natural appearance of it. To achieve this, we propose the implementation of computer vision for cooperative augmented reality by open CV using matlab.
