World is seeing a rapid growth in mobile communication and along with it is becoming difficult to maintain secrecy. There are device developments going on to mitigate this problem. The paper proposes a Mobile detection device which can be used as a metal detector to detect cell phones from the range of few centimeters to few feet's depending upon the Cell phones transmission strength and other parameters...
In this paper we present a Mobile Ad-Hoc Network (MANET) which securely transmits Audio data. Even though studies on network security has been done before, secure transmission of audio has not been given much importance since both audio and Ad-Hoc network are both complex to handle. So some simple and efficient methods are required to encrypt Audio data. We aim to provide double security by encrypting...
In this paper we analyze the performance of different channel estimators under different antenna correlation conditions. This analysis is performed for various spatial multiplexing techniques considered in 3GPP Long term evolution (LTE) Release 8 (R8) using extensive simulations. By considering the LTE downlink system parameters and the LTE channel model, we measure the performance of channel estimators...
Cognitive Radio Ad Hoc Networks (CRAHNs) constitute a viable solution to solve the current problems of inefficiency in the spectrum allocation, and to deploy highly reconfigurable and self-organizing wireless networks. Cognitive Radio (CR) devices are envisaged to utilize the spectrum in an opportunistic way by dynamically accessing different licensed portions of the spectrum[1]. However the phenomena...
The objective of the paper is to propose a power aware routing method in a geographical zone, using Bluetooth sensor's for efficient Irrigation Management System (IMS). Research on wireless sensor networks has recently received much attention as they offer an advantage of monitoring various kinds of environments by sensing physical phenomenon. The dynamic and heterogeneous nature of pervasive environment...
In the field of wireless health monitoring for specially old age people cognitive wireless sensors which can monitor the daily activities have been reported to be of great importance. Usually a large number of sensors like motion sensor, current sensor, force sensor and flow sensors are widely employed. However there are redundancies in the system and it is required to reduce the number of sensor...
Data caching is a one of the most attractive approaches used to improve the data retrieval performance in wireless mobile network. In Mobile ad hoc networks (MANETs), data items in the cache need to be updated frequently due to the high mobility of the nodes. This frequent communication leads to additional overhead and latency. In this paper, we propose to develop a cluster based cooperative caching...
Security is a major concern while implementing Mobile Ad Hoc Networks (MANET) for communication in an adverse environment. The dynamism in network topology and the absence of centralized administration, MANET is susceptible to security attacks from malicious users. This paper introduces the concept of anonymity for an informant who identifies and discloses anonymously the malicious behavior of other...
The objective of the work is to propose a dynamic authentication system for consumer supplies using Quick Response (QR) code in a Mobile Cloud Computing environment. In recent years, extensive research has been carried out on vision-based automatic identification technology that recognizes image codes using smart phones to provide various services that can recognize the authenticity of any product...
Wireless Sensor Networks (WSN) is a significant technology that has a considerable attraction in many areas, particularly in health sector. On the other hand Wireless Mesh Networks (WMN), which are an extension of LAN, have far better range and also reduce the amount of cabling needed to connect to the backbone network. In this paper a scheme that is Wireless Sensor based Mesh Networks, which is an...
