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 ...
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 ...
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 ...
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 ...
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 ...
Energy efficient data gathering protocol for wireless sensor network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Wireless Sensor Network is made up of hundreds and thousands of miniature electronic devices called node, which have sensors built on them. Functionality of a sensor is entirely application dependent. They can perform a ...
Localization of target in wireless sensor networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Advances in hardware and wireless network technology have made it possible to build and deploy dense ad-hoc wireless sensor networks of nodes collecting and disseminating information. One problem that arises in ad-hoc ...
Exploring small world effect in ad hoc network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Small world is a highly clustered i.e., a densely and fully connected network, with low degree of separation between the nodes. These networks have inherited the high clustering property of regular networks and low average ...
Wireless sensor network based automatic meter reading: WSNAMR
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Automatic Meter Reading is technology evolved from 1995[3] or before, for remote collection of utilities measurement data which involve Electricity, Gas and Water etc. In this process of evolution every time new idea was ...
