For sensor networks consisting of battery-powered sensor nodes, power saving is significant challenge. It is effective to reduce the amount of communication for sensor networks where power resource is scarce, because sensor nodes consume energy most in communication. We propose a routing protocol, HVGF (Hop-Vector based Greedy Forwarding), which reduces the amount of communication and doesn't need geographic information. In this method, we introduce n base points, and assign n-dimensional hop-vector consist of number of hops from each base point to each nodes. Then, each node forwards packets greedily based on distance between hop-vectors of the node and destination. The simulation results show that HVGF works well in the low density network compared to existing greedy forwarding method using information of real geographical position.
