The energy of sensor nodes\r\nshould be saved to prolong lifetime of the network. Energy consumption can be reduced by\r\ndividing the sensor nodes into groups, clusters. Clustering protocols are executed in\r\nrounds, one round includes usually four steps: cluster head selection, cluster formation,\r\ndata aggregation and data transfer. The selection of the clustering protocol can be\r\nchallenging, due to many factors that influence the choice of the right protocol. Objectives\r\nof the clustering protocols can vary and often depend on the application\r\nrequirements. Cluster head properties can also vary a lot and the cluster head can be\r\nselected probability based, deterministic or preset. In the cluster formation phase for\r\ninstance, you should consider the number of clusters, the size and density as well as the\r\ninternal topology of the clusters. In addition, the data aggregation point must be positioned\r\ncorrectly and evaluate the effects that aggregation delay may cause. Also intra-cluster and\r\ninter-cluster communication must be taken into account when choosing the clustering\r\nprotocol. Routing is discussed in own chapter in this study, because communication is a\r\nkey part of the clustering protocol activities. This study also discusses about the noise and\r\nnoise monitoring in the wireless sensor networks. It also presents the wireless sensor\r\nnetwork that monitors noise of the stone crusher, as well as compares operation of MHLEACH\r\nand DSBCA clustering protocols in that network.", "language": "", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Jukka Nissi (juanniss) on 2016-01-10 08:54:15.149735.
