Embedded Networks in Mobile Devices

Abstract

The concept of a mobile phone has recently transformed into a new concept of mobile multimedia devices capable of performing multiple complex tasks and integrating multiple functionalities. It has resulted in a significant increase of device integration costs and complicated deployment of new technologies. Device integrator companies favor modularity everywhere possible, which results in a new trend toward networked architectures for the mobile devices. However, comparing to the best-known embedded network solutions, e.g., SoC and NoC, these architectures have unique constraints and requirements, which also are significantly different from the wide area networks. The main constraints are power consumption and having a modular architecture to allow reuse of the components. Transition to the new architectures for mobile devices is a time consuming task that requires the analysis of many solutions applied in other contexts, especially for embedded protocols, QoS and resource management. This article reviews the state of the art in embedded networks research and the key assumptions, restrictions and limitations faced by designers of embedded networks architectures for mobile devices.

Quality of Service in Embedded Networks

“…Networked embedded systems are essentially spatially distributed embedded nodes (implemented on a board, or in a single chip in future) interconnected by means of wired or/and wireless communication infrastructure and protocols, interacting with the environment (via sensor/actuator elements) and with each other, and, possibly, a master node performing some control and coordination functions to coordinate computing and communication in order to achieve certain goal(s), (Zurawski, 2006). There are wireless, sensor and wired embedded networks, (Balandin, 2010). If we take into consideration only wired embedded networks, than they could be classified to Chip-to-chip, Die-to-die, On-chip networks based on nature of the physical interconnection, (Balandin, 2010).…”

“…Performance of modern embedded systems depends on network architecture and structure. Some embedded networks support data transmission with QoS, (Balandin, 2010). Currently many different standards are used in network design.…”

A Survey of Multi-Modal Image Fusion Methodologies

“…Embedded devices are often smaller in size and have lower CPU power. Furthermore, a devoted system is one that has been designated to perform particular tasks [1]. For instance, the library's web host and the web servers can be hosted on various computing systems, and this is considered as dedicated systems if the objective of these systems is to completely host the web servers or offer the information.…”
