Innovative mobile applications are transforming today’s enterprises as they evolve to adapt to a complex competitive landscape and a highly mobile workforce. Apps can streamline business processes, help drive innovation, reduce expenses and boost revenues, without costing the earth. Take a closer look at the facts and case studies outlined in this whitepaper to keep ...

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, 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 ...

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 ...

There is lot of energy wastage in sensor nodes of wireless sensor network. But there are many techniques and protocols that conserve energy. There are many leach protocols like leach-f, leach-c, leach-r, etc. This paper is accomplished as an improvement to the leach-r protocol thereby giving another name to this protocol i.e. enhanced leach-r protocol. ...

Ad hoc is wireless, in dependable infrastructure dynamic and self-organize network creates among different mobile host. Network generally exists in a Disaster recoveries, military activities emergency operation. Routing protocol has a major role in mobile network, which are affected from different attacks. Ad hoc On demand Distance Vector (AODV) routing protocol is suitable for routing ...

In Third Generation Partnership Project (3GPP) Long Term Evolution (LTE), the frequency planning with reuse of one is aim to provide high bandwidth service to the user but such a frequency planning strategy can lead to unacceptable inter-cell interference levels experienced especially by users located at the cell edge area. In this paper, two methods, ...

A structure less network is termed the mobile ad-hoc network, wherever all the nodes square measure independent. In MANET (Mobile Ad hoc NETwork), there’s a group of mobile nodes that from temporary network. Those nodes are act sort of a host or sort of a router. The safety issue is that the main drawback of ...

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 ...

As everyone know that TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are internet protocols which are used for communication through internet. The communication takes places through TCP and UDP using packets. In this paper, the authors purpose to analysis packets of TCP and UDP while sending an e-mail using a tool called wireshark. ...

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 ...

The microstrip patch antenna is now very famous due to its compact size, good gain and directivity bandwidth is mostly not very good in microstrip patch antenna but in this paper bandwidth of the antenna is very high, satellite communication there is a need of very compact antenna. This paper presents the designs of compact ...

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. ...

For the ad-hoc networks requiring strong privacy protection, privacy-preserving routing protocol is a crucial need. Unfortunately, none of the proposed or available protocols such as routing offers properties such as complete unlinkability and unobservability, the data and control packets being linkable and distinguishable. The USOR protocol has given a try to fulfil the requirement of ...
