A key feature of such networks is that their nodes are untethered and unattended. Distributed techniques are expected in WSNs. Computing Connected Dominating Sets (CDSs) have been widely used for virtual backbone construction in WSNs to control topology, facilitate routing, and extend network lifetime. This paper proposes a new distributed algorithm for CDS construction in WSNs. The algorithm is intended to construct a CDS with the smallest ratio when compared to its centralized version. Moreover, this paper proposes a localized algorithm that efficiently maintains the backbone when some backbone nodes decide to enter the energy saving sleep mode. We attempt to prolong the lifetime of the constructed CDS by allowing nodes with higher residual energy to have more chances to be part of the constructed and maintained backbone. Simulation shows that our distributed approach has a maximum ratio of 1.53 to the centralized approach, and it satisfies all of the geometrical properties of its canalized version. Based on this ratio, this distributed algorithm has an approximation factor of 7.65 to the optimal CDS. To the best of our knowledge, this approximation is the smallest among all existing distributed CDS construction algorithms.","PeriodicalId":127644,"journal":{"name":"IEEE International Conference on Wireless for Space and Extreme Environments","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127833625","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}

Unfortunately, the accuracy of the ranging techniques such as time of arrival (TOA), time difference of arrival (TDOA) and angle of arrival (AOA) can be significantly degraded by LOS instabilities in the underwater medium due to increased multipath effects. This paper proposes a novel underwater signal reflection-enabled acoustic-based localization scheme (UNREAL) that employs both LOS and surface-reflected non-line-of-sight (NLOS) ranging information to locate a node that has drifted away. The LOS and NLOS links are classified by incorporating a surface-based recovery mechanism, which recovers the channel impulse response information through homomorphic deconvolution. A closed-form least square method is developed to use such classification to locate the node by either using the LOS AOA measurements and/or the NLOS AOA from the estimated water surface reflection point. Every node in the network can be used as a reference point to locate the lost node when LOS AOAs are available. In this context, AOAs are a collection of elevation and azimuth angles for each reference nodes in the 3D underwater environment. Simulation results are carried out by using the projected view of a 3D camera unto the water tank to create a 3D underwater cubic environment used in validating the approach.","PeriodicalId":127644,"journal":{"name":"IEEE International Conference on Wireless for Space and Extreme Environments","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130734801","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 the industrial environments, link reliability is vulnerable to various interferences. Therefore, many schemes have been employed for reliability improvements, e.g. frequency diversity, path diversity etc., which put forward the demand on link reliability model. However, there has been little work modeling the temporal and frequency variations of the link reliability. The contributions of this paper are modeling the link characteristics of IEEE802.15.4 radio transceiver on all 16 channels based on Packet Drop Rate (PDR) data sets collected in typical factories and a link layer reliability model (LLSM), which focuses on the quantitative relationships among link reliability, time and frequency. It is found that the PDR in a certain range follows logistic or log-logistic distribution, and the interval of two sequential failed in Packet Drop Sequence (PDS) follows log-normal distribution. The model is implemented as simulation framework component and used to evaluate the influence on frequency diversity design by the simulation of two proposals of IEEE 802.15.4e.","PeriodicalId":127644,"journal":{"name":"IEEE International Conference on Wireless for Space and Extreme Environments","volume":"185 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114936277","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, wireless sensor networks require scalable time synchronization for implementing distributed tasks on multiple sensor nodes. This paper proposes an energy efficient Coefficient Exchange Synchronization Protocol (CESP) based on a receiver-receiver synchronization scheme that minimizes the impact of access-time delays. Most of the existing synchronization protocols focus on improving the synchronization accuracy while neglecting energy consumption. The proposed time synchronization protocol achieves a synchronization accuracy as good as the classic Reference Broadcast Synchronization (RBS) protocol but resulting in a dramatic reduction on communication overhead to achieve a low energy consumption. CESP works in a fundamentally different way from RBS: in order to synchronize two receivers, RBS exchanges all beacon packets between the two receivers, while CESP receivers first process a large number of received beacon packets and only exchange the minimum amount of information between the two receivers, i.e., synchronization coefficients. The synchronization performance is evaluated and compared with that of other well-known synchronization protocols.","PeriodicalId":127644,"journal":{"name":"IEEE International Conference on Wireless for Space and Extreme Environments","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127360667","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}
