Considering the aforementioned fact, the architecture of C. Service Management layer IoT should be flexible layered 1. As there is no It is a middleware layer that after identifying the names commonly accepted IoT architecture, authors proposed and address provides service to its requestors. It is the various architectures, few among them are SoA based layer with the help of which IoT is capable of connecting architecture proposed by Atzori et al. 2 and five-layered with heterogeneous things. architecture 86. D. Application layer The Application layer is associated with delivering services to the customers. For instance, it can give the acceleration of the vehicle as well as an exact location of the vehicle. Various application domains include Smart Home, Smart Grid, Intelligent Transport, Smart Factory, Quick-witted HealthCare intelligence and more. Application layer incorporates CoAP (Constrained Application Protocol), AMQP (Advanced Message Queuing Protocol), DDS (Data Distribution Service), MQTT (Message Queue Telemetry Transport), XMPP (Extensible Messaging and Presence Protocol) protocols. These protocols are discussed in next section. E. Business layer The Business layer also named as management layer (a) manages all layers, activities, and service of IoT. It incorporates certain graphs, flowcharts, and models based on the data acquired from the application layer. This layer is capable of making effective decisions for big data analysis. IV. PROTOCOLS ASSOCIATED WITH APPLICATION LAYER OF IOT The Application layer of IoT system architecture furnishes user services by following certain rules and procedures called Application layer protocols. These protocols include: CoAP (Constrained Application Protocol). MQTT (Message Queue Telemetry Transport). (b) XMPP (Extensible Messaging and Presence Protocol). Fig.3.

A detailed description of these protocols is no acknowledgment is received. discussed as follows: 2) Delivered at least once – Message is delivered at least once and for each delivery acknowledgment A. Constrained Application Protocols (CoAP) is received. 3) Delivered exactly once – In order to guarantee CoAP is a retransmission protocol that features request and response messaging. It was standardized by Internet message delivery, 4-way handshake procedure opts. Engineering Task Force (IETF) constrained Restful environment. CoAP was basically designed for resource The Client-Server of MQTT comprises of 3 elements: constrained devices like WSN (Wireless Sensor Networks). The main functionality of CoAP is 1) Subscriber. monitoring, controlling remote devices as well as guarantying message delivery. CoAP leverages HTTP 2) Publisher. 3) Broker. commands GET, POST, PUT and DELETE for interactions between client and server. It relies on UPD Every server in this architecture is referred to as broker. (User Datagram Protocol). CoAP is divided into two sub-layers namely message Client subscribes to a topic generated by the publisher. The Publisher on the other hand forwards the generated sub-layer and request/response sub-layer. The former ensures reliable communication based on exponential topic to the broker. For Instance, Consider three clients A, B, and C. Here Client A is a Publisher that publishes a back off and later deals with REST communications. CoAP is proficient in providing Datagram transport topic „air humidity‟ and Client B and C subscribes to this topic. Now, whenever Client A publishes the value of air layer security (DTLS) that provides privileged message communication, minimizing communication overhead humidity says 49 then the intermediate broker gives access of this value to all the subscribed Clients. and monitoring resources by utilizing publish/subscribe mechanism. Confirmable, Non-Confirmable, Acknowledgment (Piggybacked) and Separate Response are four types of CoAP messages. CoAP has a 32 bit message format. Fig. 4 shows CoAP message format. It incorporates CoAP version (V), Transaction Type (T), OC (Option Count), Code and Message ID (M ID) in header field followed by Token, Options and Payload fields. Fig.5.

Message Queue Telemetry Transport(MQTT) MQTT is a lightweight messaging protocol that supports machine to machine communication. It relies on TCP. In comparison to CoAP, MQTT has higher throughput but lower Latency 88. It was developed by IBM in collaboration with Arcom in 1999 and later was standardized as OASIS in March 2013. MQTT utilizes Publish/Subscribe messaging mechanism and provides SSL (Service Socket Layer) encrypted link between client and Broker. It has 3 QoS levels: Fig.6.

XMPP has its applications in social networking such as Fig. 8 represents AMQP message format. multi-user chat, video/voice calling and more. It is a platform independent protocol, have no QoS support and supports Publish/Subscribe and Request/ Response. Two or more users exchange data in the form of XML Stanza. XML stanza is cleaved into 3 components. 1) Message – it identifies source and destination address, type and IDs. 2) Presence – it notifies updates to the customers. 3) Info/query – It pairs sender and receiver.

It is a broker-less Publish/Subscribe architecture in comparison to MQTT, AMQP, and XMPP. DDS is highly reliable which provides both SSL and DTLS secure message communication. It supports both TCP and UDP transmission and has 23 QoS policies namely Security, durability, priority, reliability, etc. Table 3 demonstrates the comparison between Fig.7.

Automatic Sensor Selection Based on Task (Context IX. CONCLUSION Awareness) IoT is an emerging paradigm; it aims at providing IoT is present in everything around us; sensors are quality life by connecting things around us and deployed in these things. Since these things are billion in integration with various technologies such as Cloud number the data (big data) sensed by these sensors Computing, Big Data, Wireless Sensor Networks, etc. become difficult both for technical and non-technical IoT is considered to be highly dynamic. It automates the users to collect and interpret and process. Perra et al. 51 world around us thus providing a Smart Environment. identified this opportunity as Sensing-as-a-service and Leveraging IoT can lead to economic growth and better proposed a context-aware architecture. The challenge of sustainability. By 2025, approximately 2-3 billion people collecting and processing of sensed data is of great will access the internet also economic growth caused by concern in IoT and has become a new research area. IoT is estimated to be in the range of 2.7 trillion to 6.2 B. Heading toward Green-IOT (Constructing least trillion 55.
