With MuMHR, robustness is achieved by each node learning multiple paths and election of cluster-head backup node(s). Energy expenditure is reduced by shortening the distance between the node and its cluster-head and by reducing the setup communication overhead. This is done through incorporating the number-of-hops metric in addition to the back-off waiting time. Simulation results show that MuMHR performs better than LEACH, which is the most promising hierarchical routing algorithm to date; MuMHR reduces the total number of set-up messages by up to 65% and enhances the data delivery ratio by up to 0.83.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126545225","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}

To compare different designs and protocols with respect to both energy and delay constraints an energy dissipation model is needed that takes these aspects into account. In this paper we propose a complete energy dissipation model for wireless sensor networks that uses four operation states. These states are based on the basic sensor nodes architecture and actual working conditions of a sensor node. It also takes into account the transition between the operation states, such that a decision to change operation state can be more accurately determined. In this paper we also present measured values for both the power consumed in each operation state and the time it takes to complete a transition between two operation states.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131608784","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 standard performance measure in estimation theory is the Cramer-Rao Lower Bound (CRLB), which describes the lower bound of the variance of unbiased estimators. In the case of passive source localization, this bound depends on the sensor and source positions, as well as on the propagation speed and the assumptions made about the disturbance noise. A procedure for an optimal sensor placement, using this CRLB as the objective function, is described. In order to assure optimal coverage of a surveillance area, the average CRLB of multiple source positions (in this area) is minimized.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131507912","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}

Our paper addresses this problem by presenting a routing scheme that ensures that the monitoring network remains connected and hence the live sensor nodes deliver data for a longer duration. We analyze the role of relay nodes (neighbours of the base-station) in maintaining network connectivity and present a routing strategy that, for a particular class of networks, approaches the optimal as the set of relay nodes becomes larger. We then use these findings to develop an appropriate distributed routing protocol using potential-based routing. The basic idea of potential-based routing is to define a (scalar) potential value at each node in the network and forward data to the neighbor with the highest potential. We propose a potential function and evaluate its performance through simulations. The results show that our approach performs better than the well known lifetime maximization policy proposed by Chang and Tassiulas (2004), as well as AODV [Adhoc on demand distance vector routing] proposed by Perkins (1997).","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131860461","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}

Furthermore, the detector serves as a platform for investigations of the deep sea environment. In this context, acoustic sensors will be integrated into the infrastructure of the experiment. The main goal is to investigate the method of acoustic detection for neutrinos, which utilises the effect that a particle shower evolving from a neutrino interaction in water at very high energies generates a detectable pressure pulse. For these investigations, tests of acoustic particle detection techniques and deep sea acoustic background studies will be performed while the system is also well suited to study marine life in the Mediterranean Sea. The acoustic detection setup will comprise 6 clusters consisting of 6 acoustic sensors each. The clusters are distributed over the ANTARES detector with inter-spacings ranging from about 10 m to roughly 100 m vertically and 200 m horizontally to allow position reconstruction of point sources at different length scales. Working with a standard sampling rate of 250 k SPS, 16- bit digitisation and an optional, stepwise amplification factor from 1 to 562, the system is designed to have a dynamic range of about 3 mPa to 10 Pa (RMS) for a frequency range of about 1 kHz to 100 kHz.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125483313","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}

In particular, a sensor network on the human body or BASN is considered. The energy consumption or network lifetime of a single-hop network and a multi-hop network are compared. We derive a propagation model and a radio model for communication along the human body. Using these models, energy efficiency was studied analytically for a line and a tree topology. Calculations show that single-hop communication is inefficient, especially for nodes far away from the sink. There however, multi-hop proves to be more efficient but closer to the sink hotspots arise. Based on these findings, we propose to exploit the performance difference by either introducing extra nodes in the network, i.e. dedicated relay devices, or by using a cooperative approach or by a combination of both. We show that these solutions increase the network lifetime significantly.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122442342","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}

Therefore, OLAs do a form of cooperative transmission. OLAs, when used for broadcasting, form concentric rings around the source, and have been shown to use less energy than conventional multi-hop protocols. This paper proposes two energy efficient schemes: OLA-T for general OLA transmission and OLACRA for upstream routing in the topology of wireless sensor networks. OLA-T uses a transmission threshold to suppress nodes that would make weak contributions. OLA Concentric Routing Algorithm (OLACRA) exploits the concentric ring shapes of broadcast OLAs to limit flooding on the upstream connection. OLACRA-T is OLACRA with a transmission threshold. OLACRA-T and other variations of OLACRA are evaluated in terms of energy savings relative to a full flooding approach and probability of successful upstream routing. OLA-T and OLACRA-T are shown to save over 50% and 75%, respectively, of the energy relative to OLA flooding.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"366 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124594117","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}
