A reliable and security method for data aggregation in WSNs

Abstract Data aggregation in wireless sensor networks (WSNs) eliminates the data redundancy and is widely accepted as an essential paradigm for energy efficient routing in sensor networks. In this paper, we describe a protocol called RDA which associates a packet's reliability in data transmission with the amount of information it contains and gives the packet containing more information higher reliability in data transmission by adjust the degree of redundancy. Our algorithm is not associated with some special routing schemes, hence it can be used in any kinds of routing schemes for wireless sensor networks especially where data aggregation takes place and ensure a data packet with more information be transmitted more reliably and in that way reliability per energy could be improved.
