The concept of applying Alien Wave-lengths (AWs) for network expansion was successfully illustrated via deployment of multi-domain/multi-vendor end-to-end OTN services. We evaluate the impact of AW service establishment on both native and other alien services. Our experience confirms the technical feasibility of the concept in the context of transparent network-to-network interconnection at the optical layer. Furthermore, main operational challenges are discussed.","PeriodicalId":229123,"journal":{"name":"2013 International Conference on Computing, Networking and Communications (ICNC)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126256007","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}

The energy sources, whom we call actors, are mobile and move along pre-decided patterns while radiating an appropriate level of energy, sufficient enough to charge the sensors at an acceptable rate. This is the first work that investigates the impact of energy transfer, especially concerning the energy gain in the sensors, the energy spent by the actors, and the overall lifetime in the resulting mobile sensor-actor networks. We propose two event-specific mobility models, where the events occur at the centers of a Voronoi tessellation, and the actors move along either (i) the edges of the Voronoi cells, or (ii) directly from one event center to another. We undertake a comprehensive simulation based study using traces obtained from our experimental energy harvesting circuits powering Mica2 motes. Our results reveal several non-intuitive outcomes, and provide guidelines on which mobility model may be adopted based on the distribution of the events and actors.","PeriodicalId":229123,"journal":{"name":"2013 International Conference on Computing, Networking and Communications (ICNC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123344392","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}

The wavelet transform, being a multiresolution analysis tool, has been proposed to process the target spectrum to achieve both speed and accuracy. In this paper, we propose an improved algorithm, based on the characterization of spectrum singularities from their wavelet transform multiscale information for wideband spectrum sensing. The proposed algorithm performs better than the existing ones at medium-to-high noise power. In addition, modifications are introduced to the wavelet transform multiscale sum algorithm to improve its performance. We also show that the Gaussian wavelet is the best wavelet basis function for this spectrum sensing approach. Finally, new performance measures are introduced and evaluated to provide accurate assessment of wideband spectrum sensing techniques.","PeriodicalId":229123,"journal":{"name":"2013 International Conference on Computing, Networking and Communications (ICNC)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132641402","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 provide available data storage and sharing service, we propose a mobile storage architecture in MANET called LCS-MANET, in which the key algorithm is Location Centric Storage (LCS) algorithm. In LCS-MANET, the nodes are classified into two types: storage nodes and common nodes. We implement location centric data storage algorithm on storage nodes and also design the data replication algorithm upon them. In the evaluation, when nodes move slowly, the query success rate can reach 80% in LCS, and even when moving at the speed of 15m/s, the query success rate of LCS achieves over 30%. Evaluation results show good performance in the scenario of mobile networks and data availability.","PeriodicalId":229123,"journal":{"name":"2013 International Conference on Computing, Networking and Communications (ICNC)","volume":"78 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133391705","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}

This model imposes significant constraints on the ability of the Internet to satisfy the quality-of-service requirements of network applications, and results in significant inefficiencies in the use of network resources that are manifested as congestion. The result has been the need to over-provision Internet-based systems to meet the basic needs of modern communications. With the adoption of the Internet as the converged communication infrastructure for the 21st century, this is clearly not an acceptable long-term solution. One approach that has been identified to address these limitations is to enhance the Internet routing architecture to support multiple paths between a given source and destination. Significant research has been done into multi-path solutions for QoS and congestion, however a comprehensive solution for both QoS and congestion that is compatible with the Internet's datagram, hop-by-hop model of communication is still elusive. This paper reviews a solution presented in previous work, called Dominant Set Multipath Routing (DSMR), that addresses these requirements. The DSMR algorithm computes the best set of routes between each source and destination that provides the full range of performance available from the network. This set is used to route flows over paths that both meet the QoS requirements of the flow and minimize congestion in the network. Simulations are then presented which show the effectiveness of DSMR to provide 3 to 11 times the capacity of single-path routing while meeting QoS requirements and minimizing congestion.","PeriodicalId":229123,"journal":{"name":"2013 International Conference on Computing, Networking and Communications (ICNC)","volume":"2017 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132834132","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}

We propose to use LDPC codes with short codeword lengths, with the reliability-based min-sum (RB-MS) algorithm for decoding.

A system model is constructed for two collocated macro LTE networks. The developed model takes into consideration the RF propagation environment, power control scheme, and adjacent channel interference. Coexistence study is performed for a different combination of time/frequency division duplex (TDD/FDD) systems under three different guard-bands of OMHz, 5MHZ, and 10MHz. Numerical results are presented to advice the minimum frequency guard band, BS coupling loss, and UE antenna isolation required for a healthy system operation.","PeriodicalId":229123,"journal":{"name":"2013 International Conference on Computing, Networking and Communications (ICNC)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131781778","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}
