| Abstract(in English) | In the wireless sensor networks, wireless sensor nodes are placed the observation area, and transmit data to an observer by using the multi-hop communication between those nodes. Because wireless sensor nodes are small and have limited power supply, it is important to save power consumption on sensor nodes for prolonging the network lifetime. In our previous work, we proposed HGAF (Hierarchical Geographic Adaptive Fidelity) which introduces layerd structure into GAF (Geographic Adaptive Fidelity), a power saving technique using location information in sensor networks. Because HGAF limits the place of active nodes, the connectivity between nodes strongly depends on the layered grid layout and the density of nodes. In this paper, we theorically examine the network connectivity between nodes with the density of nodes in HGAF. Adding to this we evaluated the conectivity by simulation. We confirmed that many nodes are required to take the advantage of HGAF for prolonging the network lifetime. |
