Convergecast Tree Construction in Wireless Sensor Networks
Original language description
Data gathering is important research topic in the area of wireless sensor networks. The basic operation is collecting data from sensor nodes and their transfer to sink for further processing. Sensors are often powered by batteries with limited amount ofenergy. Therefore wireless sensor networks are able to work only for a limited amount of time. Network lifetime is defined as a time until the first sensor node depletes its energy. Main challenge in data gathering algorithms is to extend a network lifetime. In this paper we study a scenario where the sink needs to collect data that is sensed in a distant disc target area (surroundings of a specified geographical position) of a network. The sink is located away from the target area. Main aim is to construct convergecast tree that connects sink with target area and allows data collection from it. Particularly we are interested in maximizing network lifetime through careful construction of this tree.
