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 ...
Vehicle detection and tracking
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
