VoIP applications are being broadly employed in present networks challenging their abilities to offer an experience level of good quality to the users. Specially, new wireless broadband techniques i.e. WiMAX, deployed and their performance requires to assess for checking the performance levels of VoIP services. The quality of service is the primary challenge of implementation ...

In global mobile network, it is required to authenticate mobile users, provide secure communication channel between a user and a foreign agent using session key and guarantee users’ anonymity and untraceability. In order to improve the security of mobile roaming service, two-factor authentication which employs smart card and pass-word was introduced to global mobile network. ...

In this paper, a S-shaped multi frequency antenna is designed. The S-shaped patch is obtained from conventional rectangular patch by using a rectangular slot. The antenna is excited by the use of simple probe feed. This antenna has a very simple and compact structure and thus is easy to be fabricated. The proposed antenna is ...

In this paper, the authors describe PIC18F46k22 microcontroller based design and implementation of energy meter using IoT concept. The proposed system design eliminates the human involvement in electricity maintenance. Buyers need to pay for the usage of electricity on schedule, in case that they couldn’t pay, the electricity transmission can be turned off autonomously from ...

Wireless Sensor Network (WSN) is being emerged as a prevailing technology in future due to its wide range of applications in military and civilian domains. These networks are easily prone to security attacks. Unattended installation of sensor nodes in the environment causes many security threats in the wireless sensor networks. There are many possible attacks ...

A country which has its borders made by land faces major security threat from enemy infiltrations, with the help of ultra-modern techniques like concertina fencing, unmanned aerial vehicle and advanced imaging devices also fails to reduce the infiltration. This paper is to stop the infiltrators with the help of a simple mechatronic robot with GSM ...

Data center systems or subsystems that are pre-assembled in a factory are often described with terms like prefabricated, containerized, modular, skid-based, pod-based, mobile, portable, self-contained, all-in-one, and more. There are, however, important distinctions between the various types of factory-built building blocks on the market. This paper proposes standard terminology for categorizing the types of prefabricated ...

In this paper, the authors present an experimental study on the performance of spatial Interference Alignment (IA) in indoor wireless local area network scenarios that use Orthogonal Frequency Division Multiplexing (OFDM) according to the physical-layer specifications of the IEEE 802.11a standard. Experiments have been carried out using a wireless network testbed capable of implementing a ...

Contemporary advances in wireless sensor networks have resulted in many new protocols specifically designed for sensor networks where power awareness is most important consideration. Most of the attentiveness, however, has been given to the routing protocols on the grounds that they would differ depending on the applying and network structure. This paper surveys latest routing ...
