A reliable routing protocol for Wireless Sensor Networks (WSN) should be capable of adjusting to constantly varying network conditions while conserving maximum power. Existing Routing protocols provide reliability at the cost of high energy consumption. In this paper, the authors propose to develop an Adaptive Energy Efficient Reliable Routing Protocol (AEERRP) with the aim of keeping the energy consumption low while achieving high reliability. In their proposed protocol, the data forwarding probability is adaptively adjusted based on the measured loss conditions at the sink. So only for high loss rates, a node makes use of high transmission power to arrive at the sink. Whenever the loss rate is low, it adaptively lessens the transmission power.
