Furthermore, the prototype includes the design and implementation of the stages needed to inject the signal into the power-line and to recover the same signal in other point of the PLC network.

The aim is to evaluate the impact that the interference resulting from a realistic UWB hot spot scenario may have on the performance of a Wi-Max/IEEE-802.16 receiver. A mathematical model is developed through which the performance of the interference power produced by the UWB hot spot can be calculated. We use a pulse waveform represented as a generalized form of Gaussian pulse family that can be used in Ultra Wide Band (UWB) impulse radio systems. This pulse waveform ensures that the UWB spectrum mask established by the Federal Communications Commission (FCC) is met. The results against which the UWB interference is assessed are also developed using the specifications of Wi-Max/IEEE-802.16 systems. Several simulations have been done to both validate the analytical results and calculate the UWB interference.","PeriodicalId":292855,"journal":{"name":"2009 International Conference on Electrical, Communications, and Computers","volume":"40 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114027858","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}

For this purpose, metro lines are modelled using a nonlinear real time discrete space state representation and then the Lyapunov-based stability analysis is applied considering time delays of trains as disturbances. As a result a new set of indexes which relate time delays with the validity of the actual time schedule when falling inside a particular ‘stability area’ are defined. Results obtained in a simulated environment show that the new stability indexes are able to evaluate quantitatively and qualitatively the effects of saturation in metro lines as well as predict the need for rescheduling","PeriodicalId":292855,"journal":{"name":"2009 International Conference on Electrical, Communications, and Computers","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122672940","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}

Node authenticity in WSN is a commodity service that allows verifying that the message source is a node belonging to the sensor network, providing a countermeasure against node impersonation and message’s injection. However, such service is considered too expensive when public key cryptography is involved.
