Wireless networks, one of the most growing fields in research area suffers from a lot of problems. Wireless networks deals with connecting devices in a wireless fashion. These networks are usually deployed and managed with the help of radio communication. Wireless networks offers a lot of advantages over traditional wired networks such as flexibility, durability, ...
Wireless Sensor Network (WSN) consists of a large number of sensor nodes. Determining the actual position of each sensor node is thus difficult. Finding the exact position of each sensor forms the basis of localization. Localization in wireless sensor network refers to finding position of unknown nodes based on position of known nodes known as ...
One of the main problems with the existing ad hoc network especially in the military area is the security issue. Since the network works normally in heterogeneous mode, they may have nodes belonging to some enemy forces also which may intrude the network, get the confidential information or get hold of some other nodes and ...
Efficient design and implementation of Wireless Sensor Networks (WSNs) remain one of the most challenging researches due to their wide range of applications. As the use of Wireless Sensor Network (WSN) grow vastly, so it should require effective security mechanisms. These sensor networks may interacts with the sensitive data and operating in hostile unattended environments ...
To meet large demand for system capacity, high data rate and widespread services, the next generation wireless communication systems uses Multi Carrier Code Division Multiple Access (MC-CDMA) as its multiple access scheme. MCCDMA combines the benefits and limitation of both Code Division Multiple Access (CDMA) as well as Orthogonal Frequency Division Multiplexing (OFDM) techniques. The ...
In this paper, the authors present a new approach that is to increase the performance of a biometric system. The iris is a highly accurate biometric identifier. However widespread adoption is hindered by the difficulty of capturing high-quality iris images with minimal user cooperation. This paper also describes to increase performance of iris system designed ...
A Mobile Ad-hoc NETwork (MANET) is a self-organized wireless short-lived network consisting of mobile nodes. Therefore, security in MANET is the most important concern for the basic functionality of network. MANETs must have a secure way for transmission and communication and this is a quite challenging and vital issue as there is increasing threats of ...
Wireless Sensor Network (WSN) is used in many applications like in military, environmental monitoring, traffic, security, industrial sensing, intelligent homes, context aware computing, power grid, infrastructure protection etc. In every application of wireless sensor network, energy is a scarce resource for nodes. Nodes deplete more energy in communication and computation. This energy can be saved ...
