“…Actual game-play security is not a primary concern of this paper. However, the specific issue of game-state fidelity (i.e., consistency and cheat-resistance) forms a fundamental requirement [McCoy et al, 2005]. The reason we advocate strongly for singular arbitrators is given by examining past approaches:…”

“…A naively built system results in quadratic growth of bandwidth usage, with each and every peer expected to communicate with every other peer [Hu et al, 2006, Bharambe et al, 2008. Adding to this issue is the increased sensitivity to high latencies that certain classes of VEs exhibit [McCoy et al, 2005, Safaei et al, 2005. Games such as Everquest are more tolerant of latency issues [Chen et al, 2009], whereas First Person Shooter (FPS) games exhibit some of the tightest upper-bounds [Zhou et al, 2008].…”

“…The term resource could be taken to mean either bandwidth, processing, storage resources or even an aggregation of all three. We are inclined to use bandwidth capacity as our measure, as it is usually the most constrained with regards to DVEs and MMOGs [McCoy et al, 2005].…”

“…Improving actual connection speed between arbitrators and peers is beyond the scope of the work here. However, this issue is indirectly addressed by using upload capacities (currently the most limiting resource [McCoy et al, 2005, Bharambe et al, 2008) as the metric for the Z-axis.…”

“…Distributed VEs (DVE) remain an exciting frontier of research, exposing many theoretical problems due to its unique constraints. Foremost is its time-sensitivity, resulting from the need to provide a responsive experience to users [McCoy et al, 2005]. The most stringent subset of DVEs is that of First-Person Shooter (FPS) games, where the gameplay emphasizes fast reflexes and accuracy.…”

My deepest gratitude goes towards the following people:• My primary supervisor, Dr Ibrahim Khalil, who has stood by me and supported me throughout my candidature and whose patience is indeed at the level of saints.• My secondary supervisor, Mr Geoff Leach, for the technical discussions into geometric algorithms, and more importantly, all the advice and support as I began my journey.• Prof Zahir Tari, for his perseverance and continuous support throughout my candidature, and the School of Computer Science and IT, for the scholarships that sustained me during the early years.• My beloved brother, Saifullizan Almashor, and dearest mother, Sarah Abdullah, without whom I would have literally and figuratively not even be here.To all my friends and extended family, the gratitude within me is immense, and its receivers too numerous to mention succinctly. I love you all.

Predictive contract mechanisms such as dead reckoning are widely employed to support scalable remote entity modelling in Distributed Interactive Applications (DIAs). By employing a form of controlled inconsistency, a reduction in network traffic is achieved. Previously, we have proposed the Dynamic Hybrid Strategy Model (DHSM) as an extension to the concept of dead reckoning that adaptively selects extrapolation models based on the use of local performance criteria. In this paper, we formalize the notion of the DHSM as a generalized framework for network traffic reduction in DIAs, alongside a set of consistency metrics for use as local performance criteria.Keywords -distributed interactive applications, predictive contract mechanisms, dead reckoning, consistency, scalability. __________________________________________________________________________________________ I INTRODUCTIONA Distributed Interactive Application (DIA) is a distributed virtual reality system through which individuals can share information via individual and collaborative interaction with each other and their environment [1]. Distributed Interactive Applications offer the realization of simulated virtual worlds that embody a modern extension of communication, encompassing the concepts of shared time, shared space and shared presence [2]. The definition of a DIA encompasses a diverse range of applications that have seen rapid advances in technology and global popularity due to the widespread availability and ease-of-use of the Internet [3].The two primary factors limiting the large-scale deployment of a DIA are network latency and network bandwidth. Network latency refers to the delay in communication between two end-points, while network bandwidth refers to the rate at which data can be communicated per unit time between two end-points. High network latency and low network bandwidth capacity represent the largest contributors to the difficulties faced by DIAs in maintaining and supporting: (a) shared state consistency, (b) potential scalability, and (c) real-time interactivity.In this paper, we are concerned with the use of predictive contract mechanisms for the reduction of network traffic in DIAs, including the well-known dead reckoning algorithms formally defined in the IEEE Standard for Distributed Interactive Simulation (DIS) [4]. Traditional dead reckoning mechanisms often ignore available contextual information that may be influential to the state of an entity, sacrificing remote predictive accuracy in favour of low resource and computational overhead [2]. Previously, we have proposed an extension of dead reckoning, known as the Dynamic Hybrid Strategy Model (DHSM), that builds upon the foundation of the Hybrid Strategy Model (HSM) technique [5,6]. Both the HSM and the DHSM are hybrid predictive contract techniques that dynamically select remote extrapolation models based on local evaluation of current entity dynamics.In this paper, we formalize the concept of the DHSM as a generalized framework for the reduction of network traffic in D...
