foruse in a multiple accesssecurewirelesssensor network
Abdellah Chehri, Pierre-Martin Tardif · 2006
A wireless sensor networkiscomposedofa set ofsmallsensornodesdeployed inan ad hocfashion that cooperate forsensing aphysical phenomenon (e.g, temperature, humidity, luminosity). Eachsensornodeplaysa dualrole asa dataoriginator anda datarouter. Therefore a nodeis likely tocommunicate witha varying numberofitspeers. Communications receivers in thesepeer-to-peer networks mustoffer robustperformance whenreceiving signals from multiple nodesandmustoffer resistance tohostile jamming andinterferences. Inthispaper, we analyse theperformance offrequency hopping spreadspectrum foruseina multiple access secure wireless sensor networks. We usedifferent typeof detectors. Thefist isbasedontheFuzzyRankOrderDetector (FROD),andtheothers areaconventional detector usingthe MaximumRankSumReceiver (MRSR)andtheHardDecision Majority Vote(HDMV)detector. We make a quantitative comparison betweenthethreedetectors intermsoferror probability forwireless sensor networks.
