Design and Implementation of Meta-Routing with QoS Support over Heterogeneous Network in M2M Systems

Most Machine-to-Machine(M2M) systems use single radio for communication. However, different types of radios have different characteristics. For example, ZigBee and Z-Wave are low-cost, low-power whileWi-Fi is just the opposite. Heterogeneous network can provide various communication service to upper-layer applications. In addition, applications in M2M systems might cover and contain many different types of devices in the future, and this leads to various quality of service (QoS) requirements of applications. Hence, meeting a variety of QoS requirements is also an important issue in M2M systems. Therefore, our goal is to design and implement meta-routing with QoS support over heterogeneous network in M2M systems. Applications can set their own QoS requirement, and our meta-routing will make route decision based on those requirements. The best effort approach is used to satisfy QoS requirements. If the requirements can not be met, the transmission will be abandoned to save network bandwidth. Since devices in M2M systems usually have resource-limited hardware, such as small memory space, our work keeps minimum routing information on individual device instead of global routing tables. The node failure and node mobility are also taken care in our work to keep the quality of transmission.
