The Adaptive Level of Detail for Human Animation (ALOHA) system is a platform for animating virtual humans within a virtual environment using levels-of-detail for geometry, motion and conversational behaviour. Until now the behaviour of these humans has been determined using pre-defined scripts. This paper describes the integration of the intelligent agent based role-passing technique into the ...

Vehicular Ad Hoc Network (VANET) is considered one of the most promising Mobile Ad Hoc Network (MANET). One-hop broadcast which is time-triggered plays a leading basic role in VANET. Since the primary applications in VANET are life-safety related, there is a strong need of high reliability related to packet transmission and reception. Though IEEE 802.11p has been defined as an international sta...

<span>With the increase of number vehicles on road, several traffic congestion problems arise in big city, and this has a negative impact economy, environment citizens. The time spent looking for parking space generated contributes to mobility management problems. Hence need smart help drivers find vacant spaces car park shorter time. Today, researchers are considering scenarios which lar...

Prior investigations on the Aloha network have primarily focused on its system throughput. Good system throughput, however, does not automatically translate to good delay performance for the end users. Neither is fairness guaranteed: Some users may starve, while others hog the system. This paper establishes the conditions for bounded mean queuing delay and nonstarved operation of the slotted Al...

Simultaneous random access of massive machine type communications (MTC) devices are expected to cause congestion in the radio access network. Not only the performance of MTC, but the coexisting human to human (H2H) communications would also degrade dramatically without an appropriate medium access control (MAC) protocol. However, most existing solutions focus on the random access procedure with...

Absmct-In two companion papers a method for multiplexing a population of terminals communicating with a central station over a packet-switched radio channel was introduced; this method is known as Carrier Sense Multiple Access (CSMA). CSMA, as with ALOHA multi-access broadcast channels, has the unfortunate property that the throughput falls to zero as the channel load increases beyond a critica...

Recently, contention resolution diversity slotted ALOHA (CRDSA) has been introduced as a simple but effective improvement to slotted ALOHA. It relies on MAC burst repetitions and on interference cancellation to increase the normalized throughput of a classic slotted ALOHA access scheme. CRDSA allows achieving a larger throughput than slotted ALOHA, at the price of an increased average transmitt...

Renewed interest in ALOHA-based Medium Access Control (MAC) protocols stems from their proposed applications to wireless ad hoc and sensor networks that require distributed and low complexity channel access algorithms. In this paper, unlike in the traditional work that focused on mean value (throughput) and stability analysis, we study the distributional properties of packet transmission delays...

The prevailing labor market models assume that minimum wages do not affect the labor supply schedule. We challenge this view in this paper by showing experimentally that minimum wages have significant and lasting effects on subjects’ reservation wages. The temporary introduction of a minimum wage leads to a rise in subjects’ reservation wages which persists even after the minimum wage has been ...
