A cross layer approach for energy Efficient secured data transmission In wireless sesnor network

Abstract

Wireless sensor network is a network with a collection of wireless newlinesensor nodes used to observe the physical or environmental conditions newlineSensor network gains popularity by changing the way of living with wide newlinespectrum of real world data collection and event detection applications The newlinesupremacy of wireless sensor networks lies in the ability to deploy large newlinenumbers of tiny sensor nodes that assemble configure themselves to exploit newlineany possible communication path by hopping data from node to node in newlinesearch of its destination newlineThe key challenge in wireless sensor network is to prolong the lifetime newlineof sensor nodes due to the fact that it is not feasible to reinstate the newlinebatteries of numerous sensor nodes Therefore energy efficient newlinecomputational transmission protocols must be proposed Also in wireless newlinesensor networks security of the data to be transmitted is a vital issue newlinedepending on the applications as they are deployed in hostile areas newline newline
