Efficient Data Aggregation in Multi-Hop WSNs

Wireless Sensor Networks (WSNs) have drawn considerable amount of research interests for their omnipresent applications such as environmental monitoring, spatial exploration and battlefield surveillance. To design and deploy successful wireless sensor networks, many issues need to be resolved such as deployment strategies, energy conservation, routing in dynamic environment, localization and so on. All the issues essentially correlate to collecting data from a set of targeted wireless sensors to some sink node(s) and then performing some further analysis at sink node(s) which can be termed as many-to-one communication.
