S. Jeba Anandh, E. Baburaj . Energy Efficient Routing Strategies for Clustered Wireless Sensor Networks: An Analytical Framework. International Journal of Computer Applications. 74, 8 ( July 2013), 19-27. DOI=10.5120/12905-9808
The efficiency of a wireless sensor network depends on its life time. By conserving the battery power of individual sensor devices, considerable amount of total energy can be saved thereby increasing the total lifetime of the network. The operation phases of a wireless sensor network comprises of sensing the data, aggregating the data in an intermediate node, communicating and forwarding the aggregated data to the sink for further process. Among these, communication or routing process requires more energy than any other operation. Hence a better approach would be allowing only a selected number of nodes to communicate with the sink. This idea led to the construction of the sensor network as a number of clusters with a dynamically elected cluster-head node is only allowed to forward the data to the sink. Various routing techniques for clustered Wireless Sensor Networks has emerged yielding good result in improving the lifetime of the network. Here in this paper, a survey of these routing techniques are presented.
