Incorporation of mobility model of nodes in zone routing protocol for mobile ad hoc wireless networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Ad Hoc wireless networks are characterized by dynamically changing network topology due to relative motion of the nodes. This leads to the exchange of large number of control packets between the nodes to maintain the network ...
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 ...
Symbol detection in MIMO systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Multiple input multiple output symbol detection methods are observed under frequency flat fading AWGN channel condition. The modulation method employed is Quadrature amplitude modulation (QAM). The various symbol detection ...
Model based channel shortening technique for IEEE 802.11a OFDM system
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Channel shortening tehniques for IEEE802.11a OFDM system are studied. Their performance is evaluated for various standard channel models. A model based channel shortening technique is presented, which reduces the computational ...
Multi band fractal antenna for satellite application
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Fractal Antenna is the current topic for the research engineering because Fractal Technology allow us to design miniature antennas and integrate multiple band in single device. This antenna is a type of Micro strip antenna ...
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 ...
