Spectrum reservation is emerging as one of the potential solutions to cater for the communication needs of massive number of wireless Internet of Things (IoT) devices with reliability constraints particularly in mission-critical scenarios. In most mission-critical systems, the true utility of a reservation may not be completely known ahead of time as the unforseen events might not be completely...

We study the regulation of one-way station-based vehicle sharing systems through parking reservation policies. We measure the performance of these systems in terms of the total excess travel time of all users caused as a result of vehicle or parking space shortages. We devise mathematical programming based bounds on the total excess travel time of vehicle sharing systems under any passive regul...

The use of bus in traveling is a large growing business the world. Hence, reservation system deals with maintenance records each passenger who had reserved seat for journey. Moreover, ticketing includes schedule, fare and details traveling. This paper web-based application that will manage scheduling buses all terminals transport company also analyses basic needs passengers design requirements ...

In this correspondence, a dynamic reservation multiple access (D-RMA) protocol for third generation cellular mobile radio systems is proposed and its behavior is investigated under variable multimedia traffic conditions. D-RMA is a protocol which is explicitly designed to support multimedia traffic. Its structure is based on traditional PRMA++ protocol, but in addition to what PRMA++ provides, ...

Due to the On/Off nature of voice traffic, resource reservation for voice traffic in ad-hoc network is a very challenging task. On one hand, allocating resource to voice sources for all the duration of the connection results in bandwidth wasting because of the Off periods. On the other hand, releasing resources during the Off periods and reallocating them during active periods causes large and ...

In reservation-based MAC protocols, adversaries that have compromised a node can perform an efficient denial-ofservice attack by sending excessive reservation requests. Attackers, having thus prevented legitimate users from using some fraction of the bandwidth, can then use their power for jamming the legitimate transmissions instead of transmitting on the reserved channel. We propose a counter...

Most hotels increasingly emphasize direct web bookings, pursuing consumers by promising best rate guarantees. Abundant information has indicated that the proliferation of wireless Internet via mobile device is increasingly important in developing hospitality business. Mobile commerce allows consumers and businesses to build connectivity by transcending time and place. So, we believe that mobile...

Online reservation systems have grown over the last recent years to facilitate the purchase of goods and services. Generally, reservation systems require that customers provide some personal data to make a reservation effective. With this data, service providers can check the consumer history and decide if the user is trustable enough to get the reserve. Although the reputation of a user is a g...
