In a many-to-one sensor network, all sensor nodes generate CBR data and send them to a single sink via multihop transmissions. Sensor nodes sitting around the sink need to relay more traffic and suffer much faster energy consumption rates (ECR), and thus have much shorter expected lifetime. This may result in severe consequences such as early dysfunction of the entire network. While this phenomenon was reported previously in the existing literature, there is a lack of an analytical model on the… CONTINUE READING
