Communication in IoT Devices

Communication in the wireless network is a backbone for performing the network tasks. Recently, Internet of Things (IoT) devices are used to remotely monitor the system’s performance. Small-sized, smart sensing IoT devices are utilized in wireless network for this purpose. These devices are energy constrained, have less processing power, are used to sense the required environmental parameters, and communicate to the base station via Internet. Sometimes, these devices are communicating with each other for sharing the gathered information. This communication should be efficient enough to collect maximum information in the network. Hence, better communication among the devices leads to the superior performance of the network. Moreover, throughput of the network can be increased by uninterrupted and quality of service (QoS) communication among the devices. To establish a perfect communication anywhere, IoT uses communication technology. There exist various standard communication protocols for wireless network to exchange the information. This chapter provides the role and applicability of different communication protocols used in IoT devices under IoT ecosystem. Furthermore, we also present the comparison of a variety of communication protocols utilized in wireless network based on their behavior, coverage range, power consumption, and other related features. Finally, we suggest the direction and guidelines for selecting an appropriate communication protocol for IoT devices in different applications.
