Book excerpt: A PRN (packet radio network) is a collection of geographically distributed, possibly mobile users where each user is capable of transmitting and receiving messages over a shared broadcast medium. In a PRN, messages are divided into packets, which may be fixed or variable in length, and each packet is transmitted through the network individually. Packets are assembled at their destinations to reconstruct the original messages. The data traffic in a PRN is characterized by specifying the average message arrival rates to the network for each o-d (origin-destination) pair. A set of o-d rates is called feasible if there exist network protocols under which the number of packets in the network still not delivered to their destinations remains finite with probability one. The capacity region of a PRN is defined to be the set of all feasible sets of o-d rates. In this thesis, PRNs are studied from the viewpoint of feasibility, i.e., we take an arbitrary set of message input rates as given and try to determine if it is feasible. Our main conclusion is that, unless P = NP, there exists no practical algorithm for characterizing the capacity region of a PRN, in the sense that the decision problem regarding the feasibility of a given set of o-d rates in NP-complete.

This book was released on 2018-07-09 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: An amateur packet radio system operating in the very high frequency (VHF) range has been implemented in the Transport Systems Research Vehicle at the NASA Langley Research Center to provide an economical, bidirectional, real-time, ground-to-air data link. The packet system has been used to support flight research involving air traffic control (ATC), differential global positioning systems (DGPS), and windshear terminal doppler weather radar (TDWR). A data maximum rate of 2400 baud was used. Operational reliability of the packet system has been very good. Also, its versatility permits numerous specific configurations. These features, plus its low cost, have rendered it very satisfactory for support of data link flight experiments that do not require high data transfer rates.

Available in PDF, EPUB and Kindle. Book excerpt: This study is concerned with mobile packet radio networks. These networks are of importance in the context of tactical battlefield communications, where decentralized operation and antijam capability are desirable network attributes. The objective of this study is to conduct and document a survey of the known and available results on techniques for routing information through packet radio networks. We focus on issues that reside within the fust (lower) three layers of the seven-layer open system interconnection (OSI) network architecture modeL Consequently, a greater emphasis is placed on issues, such as network connectivity, media access, and routing. Where available, performance evaluation methods are detailed. Finally, we present examples of commercial, state of the art wireless data networks and discuss some open problems for further study.

Available in PDF, EPUB and Kindle. Book excerpt: It is shown that the decision problem regarding the membership of a given point in the capacity region of a packet radio network (PRN) is NP-complete. The capacity region is the set of all feasible sets of average origin-to-destination traffic rates, where the feasibility is defined as the existence of any set of rules (deterministic or non-deterministic) for moving the data through the network so that the desired rates are satisfied. The analysis includes a linear programming formulation of TDMA (time-division-multi-access) schemes for PRNs and NP-completeness results for some other related problems. Implicit in the analysis is the optimality of TDMA schemes in terms of achieving a given set of link traffic rates. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Packet switched networks provide an efficient and flexible method for interconnecting geographically distributed users for the purpose of digital data transmission. In packet radio networks, nodes transmit packets over multiple-access broadcast radio channels instead of wire, cable or fiber optics links. If the destination node of a packet is not within the power range of its source node, intermediate nodes are needed to deliver the packet in a store-and-forward fashion. Therefore, multihop packet radio networks have both the multiple-access feature typical of broadcast networks and the store-and-forward feature of point-to-point networks. Since only under restrictive assumptions is performance analysis tractable, simulation techniques must be used. (jes).

Available in PDF, EPUB and Kindle. Book excerpt: A terrestrial packet radio network, now a competitive reality, offers a new alternative for local networks. Taking advantage of its adaptability to local environments and to the growing sources of digital communications, permits extension of data communications to remote locations. While adding capabilities for dispersed computer communications, there are limitations in using packet radio due to its bursty nature and less than absolute reliability. But as a message service for short duration communications, terrestrial packet radio may rapidly fill an important gap in communications. This thesis examines the features and design considerations for a practical terrestrial packet radio network. Packet radio equipment, evolving through stages of sophistication and new generation microcircuitry, is approaching the hand held model. While new digital features improve its mobility, the crucial consideration becomes the interconnection with other systems through adaptable protocols. This issue dominates the current research.
