In this paper, the authors evaluate the performance of the OLSR pro-active protocol with and without backup routes under varying node densities and with different speed movements in the network. Additionally, this paper assists in ascertaining the effect of varying node densities on the connectivity’s life between mobile nodes in the network. Hence, it showed ...

Wireless communication is widely adopted and application oriented technology There are a huge literature about Mobile Ad-hoc NETwork (MANET) is available. In these studies, the ad-hoc network has two major issues security and performance. In this paper, a feasible and adoptable solution is introduced for enhancing security in MANET. The presented paper utilizes the network ...

In this paper, the authors consider a scenario where nodes in a MANET disseminate data chunks using rate-less codes. Any node in MANET is able to successfully decode any chunk by collecting enough coded blocks from several other nodes without any coordination. Here the problem is to identify malicious nodes that launch a pollution attack ...

Software defined radio implementation is required for LTE (Long Term Evolution) radio transceivers. An SDR (Source Demand Routing) consists of an rf front end and a Digital Processor Platform (DSP). This paper is devoted to the design and implementation of the passive part of the front end; the antennas and bandpass filters. It presents the ...

In this paper, the authors provide a study of how to design and implement Wireless Sensor Network (WSN) in NS2 (Network Simulator version 2). A Wireless Sensor Network (WSN) consists of a number of sensors which are spatially distributed and are capable of computing, communicating and sensing. NS2 is an event-driven simulation tool that is ...

As technology is growing day-by-day. Antenna is fabricated near the ground plane, which affects the overall efficiency of the antenna. In this paper, the wide band antenna with broad bandwidth that can be utilized in different frequency band. Band covers from 750 to 5000 MHZ and GSM, UMTS, Bluetooth, GPS & Wi-Fi applications is examined. ...

The exponential growth in users of computer over the years has impacted environment drastically. A primary concern of this paper is to study the transformation of computer state from grey to green. Green IT is basically referred to green computing. This paper shows how the emerging green technology reduces the negative impact of computing on ...

Clustering is an unsupervised approach to extract hidden patterns from the datasets. There are certain challenges in clustering, though it is very much difficult to produce good clustering, researchers have provided the solutions through various hybrid approaches. The proposed paper is based on enhancing the clustering results by using two algorithms: first Candidate Group Search ...

Now-a-days, the security risk management plays a crucial role, which is applied to the entire life cycle of information systems and communication technologies but still so many models for security risk management are non-practical, therefore, it should be measured and improved. In this paper, a novel approach, in which Analytic Hierarchy Process (AHP) and Quantum ...

Round-Robin (RR) is the vastly used process scheduling algorithm where, all processes are allocated some time shares in a circular order. If a process is able to complete its execution within this time quantum share, it is removed from the ready queue else it goes back at the end of the queue. Round-robin scheduling is ...
