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. ...
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 ...
Learning to rank: using Bayesian networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Ranking is one of the key components of an Information Retrieval system. Recently
supervised learning is involved for learning the ranking function and is called 'Learning to Rank' collectively. In this study we present ...
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 ...
Mobility models and its application in ad-hoc network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
The Performance of MANET application depends on several parameters like no. of nodes,
node density, communicating traffic pattern, communication range of a node, routing
protocol, battery power of a node, mobility etc. ...
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 ...
Policy based resource allocation on infrastructure as a service cloud
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Cloud computing refers to the provision of computational resources on demand. Resource
allocation is an important aspect in cloud computing. Cloud user asks for resources in
terms of a lease. Lease stores the information ...
Service integration on social network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Microblogging services are part of social network platforms, which allow people to
exchange short messages. Social networks provide people to play an active role in
collecting, analyzing and reporting news and information. ...
Generalized data extraction protocol for habitat monitoring applications in WSNs
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Habitat monitoring applications use WSNs to gather data about environment and migration patterns of animals. This data is used by biologists to analyze the life and behavior of animals in different environments. The ...
