| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In wireless sensor networks, maximizing the lifetime of the networks is a fundamental problem because of the limited electric power of the battery embedded on sensor nodes. To extend a network lifetime, it is necessary to study power consumption for data transmission in each sensor node. As a routing algorithm has a large affect on the energy consumption in each node, many power-aware routing algorithms have been proposed. However, almost all algorithms have not taken the effect of hotspot problem into account. Hotspot problem is the issue that sensor nodes around a sink node rapidly consume their battery due to heavy traffic from other outside nodes, which causes the isolation of the sensor network and prevents the sink node from gathering data from the sensor nodes. In this paper, we focus on the hotspot problem in wireless sensor networks and propose a routing algorithm to extend the network lifetime. | |
