Data-Centric Routing in a Wireless Sensor Network
Wireless Sensor Networks (WSNs) is a class of wireless ad hoc networks in which sensor nodes collect, process, and communicate data acquired from the physical environment to an external Base-Station (BS). But the fundamental challenge in the design of Wireless Sensor Networks (WSNs) is to maximize their lifetimes especially when they have a limited and non-replenishable energy supply. To increase the lifetime of the sensor network, power management and energy-efficient communication techniques at all layers become necessary. In this paper, the authors present solutions for the data gathering and routing problem with in network aggregation in WSNs. Their objective is to maximize the network lifetime by utilizing data aggregation and in network processing techniques.
