In a sensor network, sensor nodes are the potential source of information and they need to send their sensed/collected information to a remote base station (BS)/Sink. Generally, it needs a fixed amount of energy to receive one bit of information and an additional amount of energy to transmit the same. This additional amount depends on the transmission range. So, if all nodes transmit directly to the BS, then they will quickly deplete their energy. Therefore, a multi-hop routing protocol is needed to give longer life of the network. LEACH (aW. Heinzelman et al., 2000) (aW. Heinzelman et al., 2000) is an elegant energy efficient protocol where clusters are formed to fuse data before transmission to base station. By randomizing the cluster heads chosen to transmit to the base station, LEACH achieves a factor of 8 improvements over direct transmission, as measured in terms of nodes longevity. PEGASIS (aS. Lindsey and C. Raghavendra, 2001, 2002) is a chain based protocol that is an improvement over LEACH. In PEGASIS, each node communicates only with a close neighbor and takes turns in transmitting to the base station, thus reducing the amount of energy spent per round. It performs better than LEACH by about 100 - 300% for different network sizes and topologies. In this paper, we propose TREEPSI (tree based energy efficient protocol for sensor information) which gives up to 30% better performance (in terms of energy efficiency) than PEGASIS","PeriodicalId":275012,"journal":{"name":"2006 IFIP International Conference on Wireless and Optical Communications Networks","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116976280","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}

A good analysis of the limitations of the top ranking median filters, the progressive switching median filter, PSMF and the rank-order based adaptive median filter, RAMF is made and are overcome very effectively by the proposed filter which cleans the impulse corruptions of a digital image in two distinct phases of impulse detection and impulse correction. The detection phase identifies the corrupted pixels into a flag image by a spatial rank ordered approach and the correction phase modifies the corrupted pixels identified in the flag image by a more suitable rank ordered value by considering the neighboring features. The filter shows better performance than most other impulse filters, and in particular, that of the top ranking RAMF and PSMF in terms of computational aspect and objectively. The filtering technique gives good results with less patchy effects from images corrupted at higher noise levels and the results are more appealing with good fidelity at lower noise levels","PeriodicalId":275012,"journal":{"name":"2006 IFIP International Conference on Wireless and Optical Communications Networks","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126532656","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}
