Protocol design for scalable and reliable group rekeying
… The objective of this dissertation is to design a scalable and reliable rekey transport protocol and evaluate its performance. Rekey transport differs from data transport because rekey messages require scalable, reliable, and realtime delivery. Furthermore, each user needs only a small …

Transport layer protocol design over flow-switched data networks
In this work, we explore transport layer protocol design for an optical flow-switched network. The objective of the protocol design is to guarantee the reliable delivery of data files over an all-optical end-to- end flow-switched network which is modeled as a burst-error channel. We observe that …

MAC protocol design considerations for efficient mobility in wireless sensor networks
… computational algorithms and communication protocols for WSNs focus more on energy conservation rather than throughput and delay as in other wireless networks. Recently, WSN research has grown from static to mobile sensor networks (MSNs). However, there are some weaknesses in the standard …

Protocol design and analysis for a dynamic hierarchical local area network
In this thesis, the design and performance issues of a protocol for a dynamic hierarchical local area network are addressed. The dynamic hierarchy is an extension of the static hierarchical topology with the exception that the apex node can vary among a prescribed set of candidates. A simulation …
