v11 v12 33 33 In a WSN, there are two types of nodes, the normal sensor nodes which form the network, and the sink. The data packets from the normal nodes are periodically collected by the sink after some basic processing at the CH, e.g. data aggregation. The following provides the detailed information about the structure and the content of the EMR software package: 34 34 * Node \\ 35 * {{{EMRAPPc.nc}}} Contains the configuration files and the wiring between interfaces\\35 * {{{EMRAPPc.nc}}}\\ Contains the configuration files and the wiring between interfaces 36 36 * {{{EMRCHC.nc}}}\\ Contains all relevant actions and behavior of the Cluster Head (CH), e.g. collecting the informaiton of the member nodes like how many member nodes belong it, receiving the data packets from the member nodes, and forwarding the summary packet of the cluster towards the sink 37 37 * {{{EMRClusteringC.nc}}}\\ Contains the procedure about how the clusters are formed … … 89 89 90 90 * Operation\\ 91 92 91 * First, turn on all normal nodes. After a normal node is powered on, its red led will on, meaning that this node is waiting for clustering indication from the sink node\\ 93 94 92 * Then, turn on the Sink node\\ 95 96 93 * When the sink node is on, the network starts operation, e.g. the CHs are selected, the clusters are organized and the data packets from the member nodes are collected by the CHs\\ 97 98 94 * During the operation, you should be able to see that different leds are on on the nodes from time to time, where a bue led means a CH, a green led means a member node and a red led means that this node has depleted its energy and died. Please note that each change of the node led means a novel round.\\ 99 95
