Dynamic Routing Algorithm for Reliability and Energy Efficiency in Wireless Sensor Networks

초록

What are imporyant in wireless sensor are energy efficiency, reliable data transmission, and topological adaptation to the change of external environment. This study proposes dynamic routing algorithm that satisfies the above-mentioned conditions at the same using a dynamic single path in wireless sensor networks. In our proposed algorithm, each node transmits data through the optional single path using hop count to the sink and node average energy according to the change of external environment. For reliable data transmission, each node monitors its own transmission process. If a node detects a damaged path, it switches from the damaged path to the optional path and, by doing so, enhances network reliability. In case of a topological change, only the changed part is reconstructed instead of the whole network, and this enhances the energy efficiency of the network.
