Network Coding based Information Security in Multi-hop Wireless Networks
(University of Waterloo, 2010-04-28)Multi-hop Wireless Networks (MWNs) represent a class of networks where messages are forwarded through multiple hops of wireless transmission. Applications of this newly emerging communication paradigm include asset monitoring ... -
Network Robustness: Diffusing Information Despite Adversaries
(University of Waterloo, 2012-08-29)In this thesis, we consider the problem of diffusing information resiliently in networks that contain misbehaving nodes. Previous strategies to achieve resilient information diffusion typically require the normal nodes to ... -
Network-Layer Resource Allocation for Wireless Ad Hoc Networks
(University of Waterloo, 2008-08-14)This thesis contributes toward the design of a quality-of-service (QoS) aware network layer for wireless ad hoc networks. With the lack of an infrastructure in ad hoc networks, the role of the network layer is not only to ... -
