“…In [28], the metric used to evaluate the prediction error takes temporal aspects into account in order to optimize the perceived inconsistency. Chen and Zarki [10] provide an objective evaluation framework for Quality of Experience (QoE) in Games. QoE takes not only the precision but three basic perceptions into account: responsiveness, precision, and fairness.…”

“…While we do not provide a user study of how better predictions improve the quality of game play for players, the effects of these prediction errors, as the inconsistencies perceived by players, have been well studied [8,10,27,28]. Therefore, AntReckoning can be used to both improve the network requirements of games as well as the quality of game play.…”

Interest modeling in games: the case of dead reckoning

In games, the goals and interests of players are key factors in their behavior. However, techniques used by networked games to cope with infrequent updates and message loss, such as dead reckoning, estimate a player's movements based mainly on previous observations. The estimations are typically made by using dynamics of motion, taking only inertia and some external factors (e.g., gravity, wind) into account while completely ignoring the player's goals (e.g., chasing other players or collecting objects). This paper proposes AntReckoning: a dead reckoning algorithm, inspired from ant colonies, which models the players' interests to predict their movements. AntReckoning incorporates a player's interest in specific locations, objects, and avatars in the equations of motion in the form of attraction forces. In practice, these points of interest generate pheromones, which spread and fade in the game world, and are a source of attraction.To motivate and validate our approach we collected traces from Quake III. We conducted specific experiments that demonstrate the effect of game-related goals, map features, objects, and other players on the mobility of avatars. Our simulations using traces from Quake III

Abstract-Multi-player online games are inherently distributed applications, and a wide range of distributed architectures have been proposed. However, only few successful commercial systems follow such approaches, even given their benefits, due to one main hurdle: the easiness with which cheaters can disrupt the game state computation and dissemination, perform illegal actions, or unduly gain access to sensitive information. The challenge is that any measures used to address cheating must meet the heavy scalability and tight latency requirements of fast paced games.We propose Watchmen, the first distributed scalable protocol designed with cheat detection and prevention in mind that supports fast paced games. It is based on a randomized dynamic proxy scheme for both the dissemination and verification of actions. Furthermore, Watchmen reduces the information exposed to players close to the minimum required to render the game. We build our proof-of-concept prototype on top of Quake III. We show that Watchmen, while scaling to hundreds of players and meeting the tight latency requirements of first person shooter games, is able to significantly reduce opportunities to cheat, even in the presence of collusion.

“…Several recent studies have been conducted in order to elaborate objective models to assess the quality of experience (QoE) in the context of online games. In [7], the authors have identified three key parameters to measure the QoE : responsiveness, precision and fairness. The responsiveness is related to the perception of the player to the overall game process.…”

Online games are more and more popular, resulting in an increasing share in the Internet traffic. These games generate a huge number of packets with typically small payloads, which overloads the network and deteriorates its efficiency. To mitigate these problems, it was proposed to use the tunnelling, compression and multiplexing (TCM) technique. Even though it was claimed via a set of emulations that this technique would enhance the network performance, there were no theoretical nor simulation studies to demonstrate its benefits on online gaming experience. In this paper, we implement TCM in NS-3 and set up online games scenarios in order to evaluate the performance of this technique in terms of delay, jitter and order of packets. The results show that with TCM the delay and jitter are more important than the native traffic for a small number of players due to the multiplexing periods. However, this situation is reversed when the number of players is high. Furthermore, the disorder of packets is always more important with TCM. In order to reduce the delay and the packets disorder, we propose a scenario where the online players are partitioned into subgroups based on their location on the game map. Simulations show that this leads to a significant performance improvement.
