Implementing A Flexible Open Architecture Based Radio System

The proposed concept is implemented as a prototype and this document gives a detailed insight about the prototype. The prototype considers wired and wireless communication and the data exchanges between them. All the simulations are executed on a windows laptop.

Using the COM-5102, the SDR will transmit the radio signal, this pulg in will add associated MAC addresses and UDP headers onto the project automatically [15]. The VHDL code has values that can be changed slightly to accommodate UDP or TCP transmission. For the project, UDP headers will be used.

Picture being inside of a lovely building. The walls glisten as the light reflects off bouncing and giving indebtedness to the still air that holds stiff. People can be heard talking down the hall in a distance. Soon, the mind wonders to pessimistic scenarios where safety is the number one priority. A fire, a flood, the walls collapsing in on a single soul. Medical teams have to respond and silence falls down all around.

It is important to know that all access points are not safe. There are precautions Party Plates may implement when using public accesses. We should avoid connecting to unknown public access points. Never use public “open” networks to access your banking, credit card or other sensitive sites and always establish a VPN connection as soon as you connect to the Wi-Fi ("The Pros and Cons of Using Computer Tablets," 2011, p. 1)

A field programmable gate array (FPGA) is a semiconductor device that can be designed by the designer or the customer after manufacturing, hence it is known as “field programmable”. Field Programmable gate arrays (FPGAs) are truly innovatory devices that combine the benefits of both hardware and software. FPGAs are programmed with the logic circuit diagram or the source code in Hardware Description Language (HDL) to determine how the chip will work. They may be used to perform any logical function that an Application Specific Integrated Circuit (ASIC) might perform but the capacity to update the functionality after shipping provides advantages for many applications. FPGAs contain programmable logic components also called “logic blocks”, and a hierarchy of reconfigurable interconnects that permit the blocks to be “wired together” like a 1 chip programmable breadboard. Logic blocks can be designed to implement complex combinational functions or simply logic gates like AND and OR. In most FPGAs, the logic block also consists of memory elements, which can be simple flip flops or complete blocks of memory. They perform circuits just like hardware performing huge area, power and performance advantages over software, still can be programmed again economically

Mobile Networks: Mobile networks today are dominated by proprietary hardware. Having physical resource increases expenditure for the operators. Scaling of such resources may require replacement of hardware. Implementing NFV means that the hardware resource pool can be efficiently utilized based on demand. A virtualized mobile core network would also help minimize the signaling traffic on the network by grouping certain network functions together [1]. This paper will discuss more on a virtual Core network in section IV.

Nowadays most technology is becoming wireless. These inventions are making our lives much easier, and in this fast-paced world we really need it. Although some of the technological developments are just making us lazy, like the remote control. Although it makes it easy for us, some people take advantage therefore it contributes to obesity. Most of the technology has been invented for the great demand on them, it has also helped medical advances. Wireless technology just helps makes our lives run by smoother, than if we still had everything wired.

Since embedded system are targeted at very specific tasks this makes it much easier to optimize for the particular application than you could with general purpose computer[3].

It’s an undeniable fact that the Network systems domain is growing rapidly and almost on a daily basis there are new applications and systems that require Networking processors and controllers. Also with each new application the features required from a controller or processor also keeps changing. Various microcontroller manufacturers have come up with various microcontroller families to cater to these requirements. But the problem with these is that of interoperability i.e. the architecture, the programming tools, languages, debugging and testing tools vary vastly and hence becomes a major limiting factor.

Over all the world there are software programmable devices for all applications for different uses and purposes. Also there are software programmable devices that are used only for networking applications, they are called Network Processors. Network Processors have evolved over the years and have a lot of different types for same and different purposes. Network Processors are used for moving data from place to another as Routing, Switching, and Bridging, providing Services as Traffic Shaping, Security, and Monitoring, also they execute programs to handle packets in a network. They are one of the most complex systems ever created by Humans. There are many types of network processors as RISC, CISC, Mainframe, and Vector processor architectures. They uses Instruction Set Architecture (ISA) that are used for design techniques for the set of processors and for implementing the instruction work flow.

Based on the design requirement and specifications, the system block diagram shown on Figure 2.1 is developed. This block diagram defines all the function to be performed by the system. A modular approach to project design was taken. The system is designed around an Arduino Mega2560 which is based on an Atmel2560 microprocessor.

Embedded systems are found in wide range of application areas. Originally they were used only for expensive industrial control applications, but as technology brought down the cost of dedicated processors, they began to appear in moderately expensive applications such as automobiles, communication and office equipments and television Today's embedded systems are so inexpensive that they
