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 ...
Channel quality prediction and localization
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
In this thesis we focus on two problems, Channel Quality Prediction and Localization in wireless network. In High-Speed Downlink Packet Access (HSDPA) architecture of Universal Mobile Telecommunications Services (UMTS), ...
Bidding strategies for dynamic spectrum allocation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Dynamic Spectrum Allocation is the process of assigning spectrum licenses in terms of the chunks of the spectrum band to the Wireless Service Providers (WSPs). This allocation assignment is being done as per the WSPs' ...
Cache performance evaluation in DSR protocol through cross-layering for mobile ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Wireless mobile ad-hoc networks are being actively studied by many researchers these days. These networks are suitable to be used in various situations because of (i) their infrastructure-less property and (ii) the mobility ...
Ant colony optimization in routing algorithms of mobile ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
The study on performance of On-demand Ant Routing Algorithm for Mobile Ad Hoc Network is done. An ant routing algorithm based on swarm intelligence and especially on Ant Colony Optimization (ACO). It describes a noval on ...
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 ...
Testbed based experimental analysis of transport protocols over wireless ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Ad hoc networks are networks with no infrastructure and self-organized in nature. ad hoc networks allow nodes to form network when they come into range of each other provided nodes are configured in ad hoc mode. But these ...
Privacy preservation in vehicular ad-hoc networks (VANETs)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Vehicular Ad-hoc Networks (VANETs) are the special application of Mobile Ad-hoc Networks (MANETs). Due to increase in the number of road accidents, VANETs provide security to road traffic by sending safety messages to other ...
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 ...
