As we all know, the growth of computer networks continues to rapidly grow. The digital revolution has changed the way we work and communicate almost beyond recognition. Provided that, foreseeing the changes and potential compatibility problems, in the mid nineteen eighties, the international standard organization (ISO) developed a networking reference model to standardize how network systems communicate with each other. It is a logical model for how network systems are supposed to communicate with each other. It breaks down the different components of the network communication and puts them into layers which reduce complexity. This reference model consists of seven layers: Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer, and the Physical Layer. Each layer provides a service to the layer above it in the protocol specification and then communicates with the same layer’s software or hardware on other computers. It's important to realize, that these layers are separated into 2 sets: Transportation Set (Laters 1- 4) and Application Set (Layers 5 – 7). More importantly, the OSI model is 7 logical

A communications protocol characterizes the guidelines for sending pieces of information starting with one hub in a system then onto the next hub. Conventions are regularly characterized in a layered way and give all or part of the administrations indicated by a layer of the OSI reference show. A convention characterizes the operation of the convention and may likewise propose how the convention ought to be actualized. It comprises of three sections:

Unlike MQTT, the publish-subscribe model of CoAP uses Universal Resource Identi er (URI) instead of topics. This means that subscribers will subscribe to a particular resource indicated by the URI U. When a node publishes data D to the URI U, then all subscribers are noti ed about the new value as indicated in D. Since CoAP runs on top of the inherently not reliable UDP, it provides its own reliability mechanism through the use of con rmable and non-con rmable messages [55]. The observers register by using the GET request with a special observe option activated. The subject puts the observer, if it is allowed, in the list of the interested entities and responds to the observer with an immediate state of the resource. After the initial response, each subsequent noti cation is an additional CoAP response sent by the server in reply to the GET request and includes a complete representation of the new resource state [56]. CoAP also enables high scalability and e ciency through a complex architecture, which supports the use of caches and intermediaries (proxy) nodes that multiplex the interest of multiple subscribers in the same event into a single association [57] (see Figure

decided by this protocol. This protocol can be used to send data over various area networks like

Requirement for interoperability, interfacing with systems operating environment (including; capability, temperature, humidity, radiation and robustness).

Internet based Wide Area Network virtualization technologies, virtualized network functions, overlays, automation technologies, and virtual network appliance solutions must be implemented where applicable for all network layers to improve infrastructure agility, efficiency, and reduced power consumption and physical foot print.

As this demand for dynamic and unpredictable data grows, more and more devices have to be added to existing networks and configured accordingly. The need of the hour is to regulate networks centrally and as a whole rather than configure individual network devices and gain more control to achieve flexibility in existing networks.

My experience inside the research and development community and product development has given me the unique perspective to understand the mission viability of solutions and its power in making or breaking technology advancement. This perspective enhances my ability to make the most appropriate technology decisions today and tomorrow to ensure the ultimate goal of adoption is not lost in chasing unattainable solutions, those “Technical baubles”.

Cloud computing and the Internet of Things (IoT) have spent the last several years in a sort of maximum-acceleration race where they’ve lapped the other players several times over and have only one another to measure against.

Consumer Electronics Bus (CEBus), a standard proposed by the Electronic Industries Association, is based on the concept of Local Area Networks (LAN’s). CEBus based products consist mainly of a transceiverwhich implements spread spectrum technology along with a controller to run the protocol. The given protocol standards are for radio frequency, twisted pair, power line communication and a number of other networking methods. The CEBus PLDT standard specifies that a binary digit is represented by how long a frequency burst is applied to the channel i.e, a binary ‘1’ is represented by a 100 microsecond burst, whilst a binary ‘0’ is represented by a 200 microsecond burst. CEBus transmission rate varies with how many ‘0’ characters, and how many ‘1’ characters are transmitted. The CEBus standard specifies a language of object oriented controls including commands for volume up/down, temperature up one degree, etc. Due to the high noise level of power line channels, data should be transmitted via short frames, which is assured by the use of the spread spectrum technology. CEBus protocol uses a Carrier Sense Multiple Access/Collision Detection and Resolution (CSMA/CDCR) protocol to avoid data collisions. CEBus is a commercially owned protocol, and thus attracts registration fees.

Logical data store level: the level where the mobile users can share and define the same database structure.

In order to handle the device challenge, you can consider using one of the three strategies:

All the computers, in the logically and physically networks have to follow the same rules known as Protocols such as TCP/IP, IPX/SPX and NETBEUI etc. Today, there are many computer networking technologies such as LAN, MAN, WAN, WLAN, ISDN, ATM, Frame Relay, X.25, Bluetooth,
