Novel approach for localization in Ad-Hoc sensor networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
The ability of a sensor node to move itself or to otherwise influence its location will be critical in sensor networks. Today, the wireless community is putting great effort on the possibility of deploying thousands of ...
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 ...
Energy efficient secret aggregation for wireless sensor networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Sensor networks involves large amount of nodes spread over a region. Data aggre¬gation is an important technique for reducing the amount of data to be transmitted in the networks. Data confidentiality is a crucial requirement ...
FPGA implementation of direct sequence spread spectrum techniques
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This work presents the performance, noise analysis and FPGA implementation of Direct Sequence Spread Spectrum technique. Performance of signal increases as increasing parity bits in Hamming code algorithm. Increasing parity ...
Game theory based strategies for cooperation in ad hoc wireless networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
In self-organized ad-hoc wireless networks, nodes belong to different authorities, pursue different goals, have constrains like energy; therefore, cooperation among them cannot be taken for granted. Non cooperation of nodes ...
Localization for a habitat monitoring sensor network for ground turtles
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This thesis work deals with the localization problem (i.e. finding the location of the sensor nodes) in sensor networks. This work is specifically concerned with the localization of the sensor nodes on small ground turtles ...
Lifetime analysis of wireless sensor nodes using queuing models
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Prolonging the lifetime of wireless sensor networks (WSN) is one of the key issues for wireless sensor network applications. For increasing the lifetime of network, each node should conserve its energy. Sensor nodes consume ...
Detection of unauthorized vehicle movement across the forest boundary using wireless sensor networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Wireless sensor network is a collection of small sensor nodes. These nodes consist of sensing, communication and computation capability that attracts a large number of applications. Wireless sensor networks are deployed ...
Application of network coding in wireless sensor and relay based ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Network Coding (NC) is a new area which brings radical change in the way we
treat information flow in networks. NC considered being a layer 3 operation has been
shown to improve the throughput of wired networks especially ...
Distributed clustering for heterogeneous wireless sensor network in data gathering applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Wireless Sensor networks have revolutionized the paradigm of gathering and processing data in diverse environment such as, wildlife area, kindergarten or agriculture farm. The nodes in these networks usually have a very ...
