RDA: Reliable Data Aggregation Protocol for WSNs
Data aggregation in wireless sensor networks is widely accepted as an essential paradigm for energy efficient routing but with low reliability under node and link failures. In this paper, we propose a protocol called RDA which associates packet’s reliability in data transmission with the amount of information it contains and gives higher reliability to the packet which has more information by adjusting the degree of redundancy. Therefore, RDA can jointly optimize both information reliability and energy efficiency in sensor networks with data aggregation. Especially, RDA is not banded with special routing schemes; hence it can be used with any kinds of routing schemes supporting data aggregation in wireless sensor networks.
