Abstract: As for energy hole issue in Wireless Sensor Network (WSN), an energy-balanced dynamic hierarchical data forwarding strategy is proposed. According to the node usable energy, relative position and the energy consumption of cluster head in different area, the unequal hierarchical model is constructed. Furthermore, in order to realize energy efficiency of inter-cluster multi-hop communication, both node energy cost in the phase of inner-cluster communication and node relationship are considered for relay node selection, then the packet compression algorithm, a way to further reduce the forwarding packet, is performed during the process of multi-hop inner-cluster packet forwarding. The numerical results demonstrate that the proposed mechanism can balance the network load effectively, prolong the network lifetime, and improve the performance of network packet forwarding.
