A wireless sensor network is a network of miniature sensor nodes. These nodes can sense environmental parameters, execute simple instructions, and communicate with neighboring nodes within their radio range. They can be used for collecting sensory information, such as temperature measurements, from an extended geographic area.

A wireless sensor network is a network of miniature sensor nodes. These nodes can sense environmental parameters, execute simple instructions, and communicate with neighboring nodes within their radio range. They can be used for collecting sensory information, such as temperature measurements, from an extended geographic area. Operating a sensor network poses algorithmic challenges due to the limited capabilities of the sensor devices. In data gathering problems the focus is in maximizing the amount of data gathered from the sensors to a base station using direct or multi-hop radio transmission, under one or more limiting factors. We have studied data gathering in energy-constrained sensor networks. Each sensor operates on battery energy, and the battery is not replenished during the operation. Energy is consumed both in radio transmission and reception. This imposes a number of energy constraints, one for each sensor.
