Group communication in machine-to-machine environments

Abstract

M2M systems bring new horizons to the current concept of smart environments, since M2M enables a new set of services and applications. One of the main M2M features is the large number of resourceconstrained devices that usually perform collective communication. This characteristic requires the design of network solutions that support the Data Aggregation (DA) of groups of Low Duty Cycling (LDC) devices. If LDC and DA are not designed jointly, the intermittent periods caused by Low Duty Cycling make the execution of Data Aggregation impracticable or with low performance. To address this problem, this book chapter describes the Group Communication Architecture for M2M Environments (GoCAME). This architecture enables the joint execution of DA and LDC, taking into account two-way latency tolerance, and multiple data-types. GoCAME also assures the concurrent execution of data requests, managing groups of nodes to provide the best strategy to reply to each data request.
