Secure data delivery in mobile ad hoc network using multiple paths
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
A mobile ad hoc network (MANET) is a self configurable, self organized, infrastructure less multi hop mobile wireless network.Characteristics of ad hoc network make security a critical issue i.e. any node can join the ...
Optical wireless sensor network design for a conducting chamber
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Now a day’s majority of the wireless sensor networks (WSNs) are based on Radio Frequency (RF) communication technology. But RF when used in an environment like that of metallic, conducting chamber exhibits large amount of ...
Low noise amplifier design at 2 GHz
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Low Noise Amplifier (LNA) is one of the most important building blocks of any wireless
receiver. In this an attempt has been made to study two types of LNA designs. The first
design is the conventional which consists of ...
Wireless LAN 802.11 security using elliptic curve cryptography
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
IEEE 802.11 is a standard defines the specification of Wireless Local Area Network (WLAN), came into existence in 1997. As communication medium is wireless, security is a major concern to protect the data from adversary. ...
Power management of wireless sensor node by dynamic power measurement
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Wireless sensor network(WSN) is a collection of spatially distributed autonomous sensor nodes, which cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or ...
Packet forwarding strategies for cooperation enforcement in mobile wireless ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
In self-organized ad hoc networks, all networking functions rely on the contri-
bution of the relay nodes. Nodes have to forward packets for each other in order
to enable multi-hop communication. In recent years, researchers ...
Effect of location inaccuracy on deterministic coverage and connectivity protocol in wireless sensor network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Sensor networks have a wide range of potential, practical and useful applications. Energy saving is one critical issue for sensor networks since most sensors are equipped with non rechargeable batteries that have limited ...
Pulse shaping for linear time varying channels
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Pulse shaping is the one of the important an critical area for wireless communication. In this article we show the relation between pulse shaping for wide sense stationary uncorrelated scattering (WSSUS) channels and
the ...
Hardware implementation of multiband and multimode modem for software defined radio/ cognitive radio
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Present day programmable hardware and SDR (Software Defined Radio) have enabled radio processing to switch from analog to digital. The work presented here describes a method of designing a multiband & multimode modulator ...
