| Research Abstract |
For sensor networks consisting of battery-powered sensor nodes, power saving is important as well as the miniaturization and lowering the cost. We propose a routing protocol, HVGF (Hop-Vector based Greedy Forwarding), which reduces the amount of communication and doesn't need geographic information. The simulation results show that HVGF works well in the low density network compared to existing method using information of real geographical position.
