Adaptable Protocol Selection for Reliable Smart City Services.

The Machine-to-Machine (M2M) communication intends to promote seamless interaction between connecting devices to enable the automation of decision making based on aggregated data. This forms the new Internet of Things (IoT) paradigm, which aims to increase the level of system automation by enabling devices and systems to exchange and share data, facilitating the communication for other industry branches. This article addresses the requirements of implementing reliable Smart services, with consideration to the heterogeneous traffic patterns rises from the huge variant devices. The main challenges for M2M communication are driven from integrating lowpower devices, each produce a different pattern of traffic, and low bandwidth networks. The heterogeneity of integrated communications technologies, targeted service domain and data representation, highlights the need to study the communication requirements of various services and the traffic patterns in the system.
