A Node Authentication Model in Wireless Sensor Networks With Locked Cluster Generation

In wireless sensor networks (WSN), the majority of the inquiries are issued at the base station. WSN applications frequently require collaboration among countless sensor nodes in a network. One precedent is to persistently screen a region and report occasions. A sensor node in a WSN is initially allocated with an energy level, and based on the tasks of that sensor node, energy will be reduced. In this chapter, two proposed methods for secure network cluster formation and authentication are discussed. When a network is established then all the nodes in it must register with cluster head and then authentication is performed. The selection of cluster head is done using a novel selection algorithm and for authenticating the nodes. Also, a novel algorithm for authentication is used in this chapter. The validation and authorization of nodes are carried over by managing the keys in WSN. The results have been analyzed using NS2 simulator with an aid of list of relevant parameters.

TRAITS INHERITANCE AND CLUSTER ANALYSIS OF F1 PLANTS OBTAINED ON THE BASIS OF HYBRIDIZATION OF G.BARBADENSE L.VARIETIES AND LINES

This article outlines the results of analysis of farm-valuable traits inheritance of F1 plants obtained on the basis of hybridization of varieties and lines belong to G.barbadense L.cotton plant species. Dominating level and its inheritance was determined to be under positive and medium negative, dominant and super dominant forms according to the studied cotton weight, fiber length and yield, weight of 1000 cotton seeds in one cotton boll. It is required to continue genetic-breeding research work on next generations for maintaining positive heterosis status achieved at F1 generation. In order to identify the interrelation of varieties by their farm-valuable traits through analyzing group division of clusters in which varieties are combined, a four-cluster type analysis was found to be the most favorable for an effective work. KEY WORDS: species, variety, line, hybridization,inheritance, cluster,generation, cotton weight, fiber length and yield, weight of 1000 cotton seeds in one cotton boll, dominating level, super dominant, heterosis, negative heterosis.
