GSM Modem Based Data Acquisition is a process control system. It helps in collecting data from various processes present at distant places. It helps one to monitor parameters like temperature, rainfall, humidity etc. the Service personnel need not to visit distant sites for data collection .the data is collected automatically formed a data base and ...

The autonomous nodes used for monitoring environments are known as Wireless Sensor Networks. The major use of Multi-Objective particle swarm optimization for maximizing coverage & life time using wireless sensor networks is described. Wireless sensor networks are being tremendous popular due to increasing number of applications for these networks. This paper introduces a proposal to ...

Wireless sensor networks have emerged as a technology that are being quickly adopted due to their flexibility and use in a variety of environments. However, they consist of small, inexpensive devices or nodes that have severe constraints such as limited bandwidth, limited processing power, short battery life, small storage capability and are physically prone to ...

IEEE 802.1AE and IEEE 802.1AF are two IEEE 802.1X standards providing security to the data link layer. The IEEE 802.1AE is the IEEE MAC Security standard (also known as MACSec), it defines data confidentiality and integrity for media access independent protocols but lacks in providing key management and the establishment of secure associations. IEEE 802.1AF ...

A novel design of an Electromagnetic Band Gap (EBG) structure based on the Uniplanar Compact EBG (UCEBG) concept is proposed in this paper. The structure is realized by inserting split-ring slots inside two reversely connected rectangular patches, which is known as a Split-Ring Slotted Electromagnetic Band Gap (SRS-EBG) structure. The bandgap properties of the EBG ...

Renewable energy technologies have become a promising solution to reduce energy concerns that arise due to limited battery in wireless sensor networks. While this enables one to prolong the lifetime of a sensor network (perpetually), the realization of sustainable sensor platforms is challenging due to the unstable nature of environmental energy sources. In this paper, ...

A parametric analysis is performed for a wideband Archimedean spiral antenna in recognition of an emerging concept to integrate RFID along with several applications by using a single antenna. The antenna is fabricated using state-of-the-art inkjet printing technology on various commercially available paper substrates to provide the low-cost, flexible RF modules for the next generation ...

The authors present Odin, an SDN framework to introduce programmability in enterprise Wireless Local Area Networks (WLANs). Enterprise WLANs need to support a wide range of services and functionalities. This includes authentication, authorization and accounting, policy, mobility and interference management, and load balancing. WLANs also exhibit unique challenges. In particular, Access Point (AP) association decisions ...

Managing smartphones and tablets is only half the MDM story. Securing the data and access points between corporate systems and your workers’ iOS, Android, Windows, and BlackBerry devices requires just as much consideration and planning as protecting the devices themselves. This white paper explores ten policy best-practices for secure and compliant enterprise mobility, including: Industry ...

Stethoscopes are used to listen to acoustic signals from the internal organs of the human body. Although stethoscopes play a very important role in the diagnosis process, the chest piece and the connecting cable are known to facilitate transmission of pathogens from patient to patient and from patient to the user. Replacing the connecting cable ...

The benefits of BYOD become clearer, driven by instances of successful implementations and technological advancements. The biggest challenge will be managing not just the devices but the applications. This whitepaper highlights and addresses the challenges CIO’s face ensuring a single user experience across multiple platforms while supporting multiple operating system and how Enterprise Mobility Management ...

The global cyber threat landscape continues to evolve, unleashing increasingly sophisticated and persistent attack techniques at internet scale. DDoS attacks have never been more, innovative, dynamic or consequential. Espionage and crimeware activity continues to grow, as actors in this space develop and unleash increasingly sophisticated attacks worldwide, causing billions of dollars in damage and impacting ...

The reality is that DDoS attacks have been around for over 20 years. And most organizations have some form of protection in place from DDoS attacks. But over the last few years DDoS attacks have increased dramatically in size, frequency and complexity. As the threats evolve, so too do NetScout Systems’ defense strategies need to ...

The global cyber threat landscape continues to evolve, unleashing increasingly sophisticated and persistent attack techniques at internet scale. Today, attackers can release enormous terabit-per second-scale DDoS attacks. They routinely harness hundreds of thousands of Internet of Things (IoT) devices to launch attacks against specific targets that may be oceans and continents away. NETSCOUT Threat Intelligence ...
