The main idea is using hierarchical fuzzy soft \u0000clusters enabling non-exclusive overlapping clusters, thus allowing \u0000partial multiple membership of a node to more than one cluster, whereby for \u0000each cluster the clusterhead (CH) takes in charge intra-cluster issues of \u0000aggregating the information from nodes members, and then collaborate and \u0000coordinate with its related overlapping area heads (OAHs), which are elected \u0000heuristically to ensure inter-clusters communication. This communication is \u0000implemented using an extended version of time-division multiple access (TDMA) \u0000allowing the allocation of several slots for a given node, and alternating the \u0000role of the clusterhead and its associated overlapping area heads. Each cluster \u0000head relays information to overlapping area heads which in turn each relays it to \u0000other associated cluster heads in related clusters, thus the information \u0000propagates gradually until it reaches the sink in a multi-hop fashion.","PeriodicalId":58712,"journal":{"name":"无线传感网络(英文)","volume":"05 1","pages":"215-222"},"PeriodicalIF":0.0,"publicationDate":"2013-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70899040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If a capacitor is charged using a current \u0000transformer (CT) and a rectifying circuit, the charging time depends on the \u0000current flowing through a power line. In the case that the node transmits data \u0000every time when voltage of the capacitor exceeds a threshold voltage, we can \u0000indirectly measure the current by measuring the transmission intervals.

However, the measurable \u0000range is about single digit because the transmission interval decreases \u0000suddenly as the current increases. In this work, we have ex- panded \u0000the range using one CT, one wireless transmission module, and two charging \u0000circuits that include different load resistors connected in series.

Placing the short packets into appropriate slots and subslots in the TDMA frames transfers the information about the measured values and node identity.

The simulations and the testbed measurements confirm that the DTS protocol can provide energy savings up to 30% when compared with the IEEE 802.15.4 standard in unslotted Carrier Sense Multiple Access with Collision Avoidance (CSMA-CA) mode at 2.4 GHz frequency band.","PeriodicalId":58712,"journal":{"name":"无线传感网络(英文)","volume":"5 1","pages":"158-167"},"PeriodicalIF":0.0,"publicationDate":"2013-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70899835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
