Currently, new technologies have enabled the design of smart applications that are used as decision-making tools in the problems of daily life. The key issue in designing such an application is the increasing level of user interaction. Mixed reality (MR) is an emerging technology that deals with maximum user interaction in the real world compared to other similar technologies. Developing an MR application is complicated, and depends on the different components that have been addressed in previous literature. In addition to the extraction of such components, a comprehensive study that presents a generic framework comprising all components required to develop MR applications needs to be performed. This review studies intensive research to obtain a comprehensive framework for MR applications. The suggested framework comprises five layers: the first layer considers system components; the second and third layers focus on architectural issues for component integration; the fourth layer is the application layer that executes the architecture; and the fifth layer is the user interface layer that enables user interaction. The merits of this study are as follows: this review can act as a proper resource for MR basic concepts, and it introduces MR development steps and analytical models, a simulation toolkit, system types, and architecture types, in addition to practical issues for stakeholders such as considering MR different domains.

“…Augmented Reality (AR), also referred to as Mixed Reality, is a technology that layers computer‐generated enhancements (eg, images, links to web pages, and 3D objects) on top of the existing reality (ie, physical world). () It has a common origin with Virtual Reality (VR) but it differs as it immerses the user in a world with both physical objects and virtual ones.…”

Interactive applications as online games and mobile devices have grown in popularity. From their combination, new and interesting cooperative services could be generated. For instance, gamers endowed with Augmented Reality (AR) visors, connected as wireless nodes in an ad-hoc network, can interact with each other while immersed in the game. To enable this vision, we discuss here a hybrid architecture enabling game play in ad-hoc mode instead of the traditional client-server setting. In our architecture, one of the player nodes also acts as the server of the game, whereas other backup server nodes are ready to become active servers in case of network disconnection, ie, due to low energy level of the currently active server. This allows to have a longer gaming session before a disconnection occurs due to energy exhaustion. In this context, the server election strategy with the aim of maximizing network lifetime is not so straightforward. To this end, we have analyzed this issue through a Mixed Integer Linear Programming (MILP) model considering static network topologies and both numerical and simulation-based analysis shows that the backup servers solution fulfills its design objective. Contemplating for mobility, we present a simulation study employing actual packet routing protocols and discuss the tradeoffs that emerge. KEYWORDSbackup server, MANET, mixed integer linear programming, online game INTRODUCTIONIn recent years, interactive applications such as online games and mobile devices have become more and more popular, generating a huge market.This success is also accompanied by tough technical challenges that have attracted the interest of researchers and practitioners all around the world.Indeed, although online games require only a little amount of bandwidth, their performance is subject to strict per-packet delay requirements and to scalability issues that can be solved only through specific solutions and architectures. 1-3The combination with wireless-enabled mobile devices fosters new gaming scenarios. For instance, think of a multiplayer game based on the user position and proximity, ie, a game that is played outside, on the street, or in courtyards, or close to cultural heritage sites. 4 Players may gather around a certain spot and start a gaming session on their mobile devices, exploiting the device features (eg, connectivity, GPS, gyroscope, etc), rendering the game play more attractive. These applications may be coupled with Augmented Reality (AR), or even with Virtual Reality (VR), through helmets and wireless connectivity so as to enable players to interact with the AR/VR world and with each other (eg, see Figure 1). [5][6][7][8] In these envisioned scenarios, players will be engaged in an outdoor, connectivity-, and proximity-based game. However, in order to enable this scenario, we have to address at least three main issues. First, the main model for networked games is client-server, with the client run by the player's PC and the server located remotely in the Internet. 9-11 Clearly, we could ha...

“…Augmented Reality, also known as Mixed Reality, is the technology that enables to superimpose digital data (e.g., images, links to web pages, 3D objects) upon a user's view of the real world [16][17][18]. It is clear how AR descended from Virtual Reality (VR), however, whereas the latter completely immerses a user in a digital environment, the former combines digital and physical world.…”
