In the Wireless sensor network small size based and low power sensor nodes spreads over a complete geographical area which is connected to each other for performing or control the applications. Every application requires a control center which collects the aggregates data from all sensor nodes. Data aggregation is used for compress data and also for power saving which gives time efficient method for...
A critical function of wireless sensor networks (WSNs) is data gathering. One is often only interested in collecting a specific function of the sensor measurements at a sink node, rather than downloading all the raw data from all the sensors. In this paper, we study the capacity of computing and transporting the specific functions of sensor measurements to the sink node, called aggregation capacity,...
In a cluster-based wireless sensor network, to shorten the duration of a data aggregation process, wireless sensor nodes in different clusters may be required to perform concurrent transmissions. Inter-cluster interferences are usually resolved by using different channels among clusters. Since channel resource is limited, for large-scale networks, co-channel interferences are unavoidable. The problem...
