Accurate location of target node is highly desirable in a Wireless Sensor Network (WSN) as it has strong impact on overall performance of the WSN. This paper proposes the application of different migration variants of Biogeography-Based Optimization (BBO) algorithms and Particle Swarm Optimization (PSO) for distributed optimal localization of randomly(More)
This paper models a complex system to analyse its reliability characteristics. The system has two possible modes-normal and failed with two types of repair facilities-major and minor. The system can fail due to failure of any units which can fail in n-mutually exclusive ways or common cause failure. Each component of the system has a constant failure rate.(More)
Biogeography-Based Optimization (BBO) is one of the recently developed population based algorithms which has shown impressive performance over other Evolutionary Algorithms (EAs). BBO is based on the study of geographical distribution of biological organism over space and time. The solutions for problem under consideration are named as habitats whereas(More)
Biogeography-Based Optimization (BBO) is one of the recently developed population based algorithms which has shown impressive performance over other Evolutionary Algorithms (EAs). BBO is based on the study of geographical distribution of biological organisms over space and time. Yagi-Uda antenna design is most widely used antenna at VHF and UHF frequencies(More)
This paper develops a new mathematical model of a system with a novel approach, which consists of two independent repairable subsystems. The model is analyzed under " Head-of-Line " repair policy considering two types of repair between two successive transitions at a stage contrast to the normal practice of assuming single type of transition in all states.(More)
Particle Swarm Optimization (PSO) and Biogeography Based Optimization (BBO) are most popular swarm based optimization algorithms those have shown impressive performance over other Evolutionary Algorithms (EAs). Yagi-Uda is one of most widely antenna designs used at High Frequency (HF) and Ultra High Frequency (UHF) due its high gain, low cost and(More)
Mobile Ad-hoc network is a decentralized, self-organizing network. At present trend the MANET become one of the most important wireless communication mechanisms among all other. Unlike traditional network, MANET does not have any fixed infrastructure. Every single node in the network work as both a receiver as well as transmitter and node can communicate(More)
