Wireless Sensor Networks (WSNs) when combined with various energy harvesting solutions managing to prolong the overall lifetime of the system and enhanced capabilities of the communication protocols used by modern sensor nodes are efficiently used in are efficiently used in Smart Grid (SG), an evolutionary system for the modernization of existing power grids. However, wireless communication technology brings various types of security threats. In this study, firstly the use of WSNs for SG applications is presented. Second, the security related issues and challenges as well as the security threats are presented. In addition, proposed security mechanisms for WSN-based SG applications are discussed. Finally, an easy- to-implement and simple attack detection framework to prevent attacks directed to sink and gateway nodes with web interfaces is proposed and its efficiency is proved using a case study.

The k -tuple domination problem, for a fixed positive integer k , is to find a minimum size vertex subset such that every vertex in the graph is dominated by at least k vertices in this set. The case when k = 2 is called 2-tuple domination problem or double domination problem. In this paper, the 2-tuple domination problem is studied on interval graphs from an algorithmic point of view, which takes O ( n 2 ) time, n is the total number of vertices of the interval graph.

Total plant leaf area of individual maize plants ( Zea mays L.) at anthesis was estimated by multiplying the area of leaf number seven, the best estimator in these studies based on correlation analyses, by an appropriate “leaf area factor.” This factor was determined by dividing total plant leaf area by the area of leaf seven, which was the largest or nearly the largest leaf for the 23 genotypes studied. For precise estimation, a factor should be determined for the largest leaf of each genotype or treatment in each population and each year. A very close correlation between estimated and actual leaf areas was observed when the leaf area factor was used. To minimize the error incurred by plant-to-plant variation, at least five plants should be completely measured to determine the leaf area factor for a given genotype. This method of estimation could be applied widely to leaf area measurements in maize and should make it possible to determine leaf areas in yield trials, breeding nurseries, and extensive field tests.
