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 …

Design of a Transport Layer Protocol for 4G Wireless Systems, Mobility
… paradigm of the future. Future network protocols will be 4G defined over an entirely packet-switched network with digital network elements, high bandwidth and built-in network security. The bandwidth provided will be 100Mbps for stationary objects and 20 Mbps while in motion. 4G wireless …

Evaluation of Transport Layer Protocols for wireless multi-hop networks
… networks, coordinated management, intelligent transportation system. WMN is gaining significant attention as a feasible way for Internet providers (ISPs) and other end-users to establish robust and reliable wireless broadband service access at a reasonable cost. Quality of Service (QoS) …

TCP congestion control using reinforcement learning
TCP, a transport layer protocol which ensures the reliable delivery of information on the network, is the basis of Internet connectivity, with 85% of the worlds Internet traffic being TCP based. TCP however, is slow to adapt to changes in the network, drastically reducing the throughput at the …

A Novel Approach for Implementing Worldwide Interoperability for Microwave Access for Video Surveillance
… QoS requirements. In the medium access (MAC) layer, this thesis proposes a bandwidth allocation scheme that considers the QoS uniformity of the traffic sources. The proposed bandwidth allocation scheme comprises a simplified bandwidth allocation architecture, a packet-aware bandwidth request …

End-to-end data reliability in optical flow switching
… end-to-end reliable data delivery part of the Transport Layer protocol and propose effective and efficient algorithms to ensure error-free end-to-end communications for OFS. We will analyze the performance of each algorithm and suggest optimal algorithm(s) to minimize the total delay. We …

Experimental Evaluation of Convergence Layers in Delay Tolerant Networks
Traditional Internet protocols like TCP/IP and UDP/IP are not designed to perform efficiently in Delay Tolerant Networks (DTN) environments that operate in environments with high delays, significant losses, and intermittent connectivity. DTN uses the Bundle Protocol (BP) in the Bundle layer for …

Providing availability in the lower layers of a wireless network: philosophies and case studies
… of information security. Indeed, a device, protocol, or network can enjoy the highest level of confidentiality and integrity, but still be of very little value to its clients if it is not available. In this dissertation, I consider the availability of wireless networks, which have permeated …

Simulation of the error control procedures in the Xpress Transport Protocol
… media, the demand for a more efficient transport layer protocol is increasing. Many research activities have been devoted to this area. The Xpress Transport Protocol (XTP) is one such example. XTP was designed to fix some deficiencies in the Transmission Control Protocol (TCP), and to …

From specification to realization: implementing the express transfer protocol
… described in this thesis deals with effective protocol specification. The primary question addressed is whether the Express Transfer Protocol (XTP), a "real-time" Transport layer protocol, is sufficiently specified or are there "holes" in its specification? A new protocol evaluation process is …

Cater: An Opportunistic Medium Access Control Protocol for Wireless Local Area Networks
An adaptive MAC protocol is developed and analyzed that offers a "best case" scenario by allowing the MAC to control medium parameters thereby fully exploiting the channel of an ad hoc wireless LAN. This new, opportunistic medium access control protocol is called CATER (Code Adapts To Enhance …

Application-specific reliable data transfer in wireless sensor networks
… dependent. </p> <p>We present a reliable protocol for data transfer from a base station to sensor nodes for time-critical applications in WSNs with zero tolerance for data loss. The protocol is based on hop-by-hop detection and recovery of lost data packets, out-of-sequence forwarding of …

Methods for Testing QUIC Network Protocol Implementations
QUIC is a secure transport layer protocol optimised for performance. It was ratified by the IETF in May 2021 and represents a key part of the HTTP/3 standard experiencing rapid adoption. The protocol offers an alternative to secure transport currently offered with TLS over TCP. QUIC’s main …
