Acceptance Test for Fault Detection in Component-based Cloud Computing and Systems

Abstract Fault Detection is considered as one of the main challenges in large-scale dynamic environments and thus, for maintaining the reliability requirements of Cloud and Mobile Cloud systems. Most of the popular existing techniques for fault detection applied on the Cloud Computing environment in general, are based on system-monitoring despite the extreme difficulty of keeping track of all machines with their huge number in Cloud systems. In this paper, we propose a Fault Detection framework for the Component-based Cloud Computing by using Recovery Blocks’ Acceptance Test. This framework aims to construct Fail-Silent Cloud modules which have the ability of Self-Fault detection. In this, the detection process of transient hardware faults, software faults, and response-time failures is performed locally on each computing machine in the Cloud system. Background of the research issue, our mechanism, thorough analysis, and appropriate case study are presented. The efficiency and practicality of the proposed framework are proved by Safety verification using the model-checker.

MMSMAC: A Multi-mode Medium Access Control Protocol for Wireless Sensor Networks with Latency and Energy-Awareness

In this paper, we propose a new medium access control (MAC) protocol for wireless sensor networks called MMSMAC (multi-mode sensor MAC protocol), which operates according to the application requirements and traffic load, in three main modes: synchronous, asynchronous, and hybrid. In the synchronous mode, MMSMAC organizes the sensor nodes under even and odd clusters. Each sensor node has its own active/sleep and send/receive periods according to its cluster identifier, which ensures better load balancing among nodes. In the asynchronous mode, sensor nodes communicate freely without the utilization of even and odd clusters. We propose a mechanism to wake up the destination node and minimize the overhead. In this mode, we propose another mechanism to circumvent the problem of hidden host. In the hybrid mode, the features of asynchronous and asynchronous modes are combined. Our simulation results and analysis show that each of the MMSMAC modes shows convincing performance gains and outperforms B-MAC and Hybrid CSMA/TDMA protocols.

The state-of-the-art wireless body area sensor networks: A survey:

Wireless body area sensor network is a sub-field of wireless sensor network. Wireless body area sensor network has come into existence after the development of wireless sensor network reached some level of maturity. This has become possible due to the tremendous technological advancement leading to easy-to-use wireless wearable technologies and electronic components that are small in size. Indeed, this field has gained significant attention in recent time due to its applications which mostly are toward healthcare sector. Today, tiny-sized sensors could be placed on the human body to record various physiological parameters and these sensors are capable of sending data to other devices so that further necessary actions could be taken. Hence, this can be used for diagnosis of disease and for developing serious health-complication alert systems. Considering this recent hot topic, the intent of this work is to present the state-of-the-art of various aspects of wireless body area sensor network, its communication architectures, wireless body area sensor network applications, programming frameworks, security issues, and energy-efficient routing protocols. We have tried to cover the latest advancements with some discussion on the available radio technologies for this type of network. Future visions and challenges in this area are also discussed.

IEEE Access Special Section Editorial: Health Informatics for the Developing World

We live in a world with growing disparity in the quality of life available to people in the developed and developing countries. Healthcare in the developing world is fraught with numerous problems such as the lack of health infrastructure, and human resources, which results in very limited health coverage. The field of health informatics has made great strides in recent years towards improving public health systems in the developing world by augmenting them with state-of-the-art information and communication technologies (ICT). Through real-world deployment of these technologies, there is real hope that the health industry in the developing world will progress from its current, largely dysfunctional state to one that is more effective, personalized, and cost effective. Health informatics can usher a new era of personalized health analytics, with the potential to transform healthcare in the developing world. In conjunction with mHealth and eHealth, many other important health informatics trends—such as artificial intelligence (AI), machine learning (ML), big data, crowdsourcing, cloud computing—are also emerging. Exponentially growing heterogeneous data, with the help of big data analytics, has the potential to provide descriptive, predictive, and prescriptive health insights as well as enable new applications such as telemedicine and remote diagnostics and surgery. Such systems could enhance the overall process of monitoring, diagnosis, and prognosis of diseases.

MMSMAC: A multi-mode medium access control protocol for Wireless Sensor Networks

In this paper, we propose a new Medium Access Control (MAC) protocol for Wireless Sensor Networks (WSNs) called MMSMAC (Multi-Mode Sensor MAC protocol), which can operate and switch among three modes: synchronous, asynchronous, and hybrid, according to the application requirements. In the synchronous mode, MMSMAC organizes the sensor nodes under even and odd clusters. Each sensor node has its own active/sleep and send/receive periods according to its cluster identifier, which ensures better load balancing among nodes. In the asynchronous mode, sensor nodes communicate freely without the utilization of even and odd clusters. In this mode, we also propose another mechanism to circumvent the hidden host problem. In the hybrid mode, the features of synchronous and asynchronous modes are combined. Simulation results and analysis show that each of the MMSMAC modes shows convincing performance gains and outperforms B-MAC and CSMA/TDMA protocols.

Hybrid data dissemination protocol (HDDP) for wireless sensor networks

Wireless sensor networks (WSNs) are often used for monitoring environmental conditions. One of the most important tasks in a WSN is to gather sensed data for the users to utilize the network with adequate flexibility. In this process, it is also very important to employ energy-efficient communication protocols since sensor nodes are usually battery-powered and hence their lifetimes are relatively short. Considering these practical aspects of WSN deployment for various types of application scenarios, in this paper, we propose a data query dissemination scheme and data gathering solution. By considering energy conservation and latency, we provide parameterized query which can be adapted according to the user’s profile to collect the required readings from sensor nodes. Simulation results prove that the proposed protocol is more energy-efficient compared to the other alternatives of the same kind.

Two energy and time-efficient data dissemination protocols for large-scale wireless sensor networks

In a wireless sensor network (WSN) where positioning information is not assumed or is partially available, efficient data access is a very challenging issue especially in an environment with multiple random sources and sinks. Few years back, an interesting rumor-agent based protocol named rumor routing (RR) was proposed. The key concept RR introduced is that the agents are used to spread request and environmental information in an attempt to not affect the limited bandwidth of WSN. Moreover, in this protocol, the cooperation of agents helps build optimal paths leading to events with low energy cost. In this paper, we first review the major RR extensions classifying them into two categories: location-based and free location-based. Then, based on this classification, we propose two rumor-based data dissemination protocols designed to ensure both energy and time-efficient data access for realistic WSN deployments. The two proposed protocols have been compared with the relevant previous works through simulation campaigns. Performance evaluation results show that our proposed protocols achieve significant improvements in terms of data accessibility, generated traffic, and query latency.

Security mechanisms and data access protocols in innovative wireless networks

Wireless networks play a vital role in shaping today’s network infrastructure. Although in the past, the use of wireless communications was limited to the last-mile connectivity of the network, their convenience and adaptability has led to a variety of innovative wireless technologies that are now arriving at the scene. These include mobile technologies, 4G (LTE, WiMAX), 3G (UMTS, HSPA), Bluetooth, wireless sensor network (WSN), radio frequency identification (RFID), nearfield communication (NFC), mobile ad hoc network (MANET), vehicular ad hoc network (VANET), wireless mesh network (WMN), wireless body area networks (WBAN), and Wi-Fi. An amalgamation of these different technologies will dramatically enhance the usefulness of small-sized Internet-capable devices and potentially would offer a world of truly ubiquitous computing.

ECL-EKM: An enhanced Certificateless Effective Key Management protocol for dynamic WSN

To solve the key management related problems encountered in symmetric as well as asymmetric key based schemes, recently a public key based scheme known as Certificateless Effective Key Management protocol (CL-EKM) has been proposed for dynamic Wireless Sensor Networks (WSNs). In spite of showing numerous advantages over the previously proposed schemes, this protocol shows some critical limitations. One among these is the method of relying on unicast transmission mode to transmit messages from the Base Station (BS) to all cluster heads in the network. This is because when the network grows in size or when the number of messages to be transmitted at a given time is large, this would cause severe negative impact on the overall performance. Hence, in this paper, we consider the optimization problem of the protocol and propose a solution which enhances CL-EKM by avoiding intensive use of encryption and unicast operations that reduces the energy and delay associated with the communications between the BS and the cluster heads. The performance gains are depicted in the presented results.
