This paper is concerned with the application of
hierarchial and parallel computing structures to digital
data communications processing in a multi-access telecommunications
environment. Designs are analyzed and
evaluated in terms of data collected from remote access
tele-communications traffic and in terms of the application
to several processing problems in the...
An important objective of tactical ad hoc networks is to deliver threat information from sensors to shooters efficiently and quickly. The information sent to a particular shooter should contain warnings about threats that are within some distance and/or within some time of the shooter's current location. In this thesis we...
Network coding is a transmission paradigm that is known to achieve better network throughput in certain multicast topologies; however, the practicality of network coding has been questioned due to its high computational complexity. One of the drawbacks of using network coding is the long decoding times, this is mainly due...
Rapid advances in technology have seen computing move from a
large central computer to desktop microcomputers.
This advance was also
seen in the design of dedicated computers, computers designed to perform a
few specialized tasks or duties.
These computers, or microcontrollers, are
often controlled by a central computer and themselves...
This paper describes the design and implementation of
COLAN V, a High Performance Local Area Network for
Communications and Control utilizing a Communications Coprocessor.
The main objective of this thesis is to improve upon
the performance of previous COLANs in speed, switching
techniques and error detection techniques. This was
possible...
EDLAN is a simple, inexpensive local area network suitable for
educational applications. In EDLAN, a number of personal computers are
connected through an RS-485 global bus which carries the data
transmission among the computers. CSMA/CD protocol is used to control
the access of the global bus. The communications are controlled...
This thesis discusses the design and development of a
viable local area network (LAN) which supports both
communications and control applications. The emphasis was
to develop a practical and cost effective system which
offered high performance while utilizing low cost
components. System cost was kept low by utilizing a
twisted-pair...
COLAN (Control Oriented Local Area Network ) is a
redesign of the Task-Master, a daisy-chain structure
distributed control system. COLAN is a simple bus structure
communication subnetwork intended for distributed control
applications. Low cost and simplicity are two main design
criteria. Point-to-point and broadcast communications are
possible. A packet switching...
COLAN III is a control oriented LAN designed to achieve reasonable
network performance and flexibility at low cost. These objectives are
achieved by utilizing inexpensive microcontrollers (8031s) and hardware
support. The CSMA/CD network protocol with single bus structure has
been employed in COLAN III as an arbitration method to control...
The performance of multi-user workstations that access files
over a local area network is studied. Such file systems, called
distributed file systems, provide access of remote file systems with a
great degree of transparency. The main objectives are
To study the principles of distributed file systems. specifically
NFS from Sun...
