چکیده
Wireless Sensor Network (WSN) consists of large number of sensor nodes capable of forming instantaneous network with dynamic topology. Each node simultaneously as both router and host. Number of nodes in a WSN can vary either due to the mobility or death of nodes due to drained conditions. Low Energy Aware Cluster Hierarchy (LEACH) is a most popular dynamic clustering protocol for WSN. Deployment in unattended environment, limited memory, limited power and low computational power of a sensor node make these networks susceptible to attacks launched by malicious nodes. This paper provides an overview of LEACH protocol and how LEACH can be compromised by malicious nodes. We propose a attack on LEACH – Snooze attack. This paper we present a way to simulate this attack on NS-2 which is demonstrative on throughput. We observe that during simulation throughput drops as an effect of attack. It is observed that the effect of the attack gets aggregated as we increase the number of attackers.

Flavonoid Constituents in Some Species of Salvia L. (Lamiaceae) in Iran
Eight Salvia L. species including S. spinosa L., S. reuterana Boiss., S. macrosiphon Boiss., S. syriaca L., S. nemorosa L., S. virgata Jacq., S. sharifii Rech. f. & Esfand. and S. mirzayanii Rech. f. & Esfand. were studied for flavonoid compounds. These constituents were analyzed using two-dimensional maps on silica gel 60F thin layer chromatography. The flavonoid compounds of each species were...

متن کاملSome numerical results on two classes of finite groups
In this paper, we consider the finitely presented groups $G_{m}$ and $K(s,l)$ as follows;$$G_{m}=langle a,b| a^m=b^m=1,~[a,b]^a=[a,b],~[a,b]^b=[a,b]rangle $$$$K(s,l)=langle a,b|ab^s=b^la,~ba^s=a^lbrangle;$$and find the $n^{th}$-commutativity degree for each of them. Also we study the concept of $n$-abelianity on these groups, where $m,n,s$ and $l$ are positive integers, $m,ngeq 2$ and $g.c.d(s,...
متن کاملThe Diversity of Woody Species in the Ecosystems of Sweet Chestnut, Hazel, (Corylus avellana L.) and Italian Cypress Trees in Guilan Forests, Iran
The purpose of this study is to determine the woody species diversity in Sweet chestnut tree, Hazel-tree and Italian cypress ecosystems in the Guilan forests. A lozeng 0.5 ha sample plot was selectively established on each site. In the Sweet chestnut ecosystems , 4 sites were classified, whereas 10 sites of Hazel tree and Italian cypress ecosystems were classified based on species composition. ...
