Abstract

Pseudomonas fluorescens native isolate and Pseudomonas fluorescens strains of pf 1, pf 27 effectively inhibited the growth or Rhizoctonia solani. Seed treatment with Pseudomonas fluorescens native isolate and Pseudomonas fluorescens strains of pf1 (4 x 10⁹cfu/ml) recorded the maximum germination (98.66% and 86.66%), shoot length (20 and 18cm), ischolar_main length (15 and 13 cm), dry matter production (60 mg and 57 mg) and vigor index (1973.2 and 1618) compared to control.

Abstract

Ad-hoc networks are a collection of mobile hosts that communicate with each other without any infrastructure. These networks are vulnerable against many types of insider attacks including black hole attacks and selective data forwarding. Even if many previous works focused on authentication and cryptography techniques, nevertheless these techniques suffer from some weakness. We propose a novel secure multicast routing protocol designed to withstand insider attacks from colluding adversaries. Our protocol is a software-based solution and does not require additional or specialized hardware. We present simulation results that demonstrate that the proposed protocol effectively mitigates the identified insider attacks.
