Future microcellular systems will require distributed network control. A packet-switched network is particularly suitable for this requirement. Moreover, packet switching naturally accommodates speech activity detection to improve Vation-ALOHA protocol for packet speech transmission from wireless terminals to a base station. Because PRMA is a statistical multiplexer, the channel becomes congest...

Nowadays, developed and developing countries using smart systems to solve their transportation problems. Parking guidance intelligent systems for finding an available parking space, are considered one of the architectural requirements in transportation. In this paper, we present a parking space reservation method based on adaptive neuro-fuzzy system(ANFIS) and multi-objective genetic algorithm....

This paper studies resource reservation mechanisms that can be incorporated into distributed multi{path Quality{of{Service (QoS) routing algorithms. Three resource reservation schemes, the forward reservation scheme, the backward reservation scheme and the hybrid reservation scheme, are investigated. Protocols that combine these resource reservation schemes with a ticket{based distributed QoS r...

Fault tolerance is a key aspect of the dependability of complex computer-based systems. Fault tolerance may be difficult to measure directly in complex real world systems, and we propose here to measure it in terms of integrity preservation of the system under the assumption of a particular fault occurrence distribution. We measure the integrity preservation ability of the system by measuring t...

This paper studies resource reservation mechanisms that can be incorporated into distributed multi–path Quality– of–Service (QoS) routing algorithms. Three resource reservation schemes, the forward reservation scheme, the backward reservation scheme and the hybrid reservation scheme, are investigated. Simulations are carried out to compare the performance of the protocols and to study the impac...

In wireless cellular networks, a roaming mobile station (MS) is expected to move from one cell to another. In order to ensure that ongoing calls are not dropped while the owner mobile stations roam among cells, handoff calls may be admitted with a higher priority than newly generated calls. Predictive channel reservation (or pre-reservation) schemes allow the reservation of a channel for an ong...

This paper presents the dynamic reservation protocol for supporting variable-rate data services on time-division multiple-access based wireless networks. It allows a large number of data terminals to access data applications by sharing a reserved data-carrier. Through dynamic reservation data terminals can get their needed radio channels for uplink transmission without contention. The protocol ...

This document describes the use of a single RSVP (Resource ReSerVation Protocol) reservation to aggregate other RSVP reservations across a transit routing region, in a manner conceptually similar to the use of Virtual Paths in an ATM (Asynchronous Transfer Mode) network. It proposes a way to dynamically create the aggregate reservation, classify the traffic for which the aggregate reservation a...
