Table 8: Main characteristics comparison of the IoT Device Management platforms. Platforms and new solutions are based on the SNMP architecture protocol, as shown in [115; 116], such as the use of the OVSDB protocol for the SDN architecture and the XMPP protocol shown in IoT-PIC. SNMP uses more efficient resources thus responding to a processing request up to ten times faster than NETCONF according to the study presented in [7; 117; 118]. The OpenDayLight modular platform supports more network protocols for IoT, such as SNMP, NETCONF, IoT-PIC/XMPP, OVSDB, and additional features. Then, it can be considered the best platform among the studied IoT Network Management platforms. Figure 30 presents the percentage of the main resources obtained from the surveyed protocols and platforms for IoT management. The studies presented in [6; 11; 93; 119] show the percentage of use of the main raised resources are accounted and demonstrated. As may be seen, almost all the IoT Device Management platforms solved the heterogeneity and interoperability issue but, for network management, it stills a challenge given they only propose 6 LoWPAN network management but SDN and Mesh networks are not supported. Given the protocols and platforms, only about 50% used a standard communication model of networks and devices. Security and context awareness of networks and devices are challenges that stills open. Both types of management have an adoption of open-source protocols and platforms with about 60% of all the surveyed technologies. Some protocols or platforms have a range of features but requirements such as security and interoperability are developed in different ways for each one. Thus, no IoT management platform and protocol meets all the requirements. Based on this study, it is concluded that IoT Device Management stills in an early stage. The requirements have not been completely explored. Nevertheless, ManIoT and ONEM2M can be considered the best open-source solutions. ONEM2M supports a wide range of management protocols. Xively is the best proprietary platform according to the mapped characteristics. No solution can cover all the requirements of a RAs. Thus, there are open research issues due to divergences between the available technologies and research approaches.
