Mobility aware MANET routing protocol using cross layer design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Mobile Adhoc Network (MANET) is a dynamic network with time varying topology and time varying network resources. Due to the error-prone wireless channel and high mobility, traditional protocols of wired networks cannot be ...
Modeling MANETs using queuing networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Mobile Ad Hoc Networks (MANETs) are becoming an attractive solution to the services that require flexible establishment, dynamic and low cost wireless connectivity. Since nodes are mobile, routing results vary significantly ...
Channel estimation in OFDM systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Orthogonal frequency division multiplexing (OFDM) is not a new concept, but its receiver design has constant improvement. OFDM uses available spectrum efficiently and the system provides high data rates. Many standards ...
Design issues in direct conversion receiver
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
The wireless system is being rapidly proliferated in our life. The growing of capacity in wireless communication requires a new type of wireless communication method which does not affect current work on circuits and systems ...
Design of multi-standard RF front end receiver using novel low IF topology
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This thesis presents the multi-standard receiver architecture and the corresponding RF front-end design supporting Bluetooth and IEEE 802.11a WLAN standards. To maximize the level of component share in the proposed ...
Comparative study between exponential back off and dynamic waiting strategies for medium access in wireless ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
IEEE 802.11 DCF (IEEE 802.11 Distributed Coordination Function) is widely used MAC protocol for wireless channel access. Although it is developed for single hop networks where all nodes are in the same radio range, it can ...
