A system and a method. The system may include a node of a network of nodes, wherein the network is configured as a modified time division multiple access (TDMA) network. The node may include a processor and a transceiver communicatively coupled to the processor. The processor may be configured to: collect data received from each other node of the network during a data collection phase of a given modified TDMA cycle, the collected data including information of connectivity between pairs of nodes of the network; and output the collected data for transmission to each other node of the network during a data distribution phase of the given modified TDMA cycle.

Modified time division multiple access (TDMA) network

A method is provided for time synchronization in a MEMS (MicroElectroMecahnical system) based system having a MEMS processor and a plurality of MEMS devices. In a specific embodiment, the method includes, in the MEMS processor, transmitting a synchronization signal to the plurality of MEMS devices and saving a local time upon transmitting the synchronization signal. The MEMS processor also receives sampled data and time information from the plurality of MEMS devices, when the data and information become available. The method also includes, in one or more of the MEMS devices, receiving the synchronization signal from the MEMS processor and storing a local time upon receiving the synchronization signal. The MEMS device also performs a sensing operation and stores sampled sense data and sense time information.
