This paper presents a method for design of two dimensional (2-D) recursive filters using bacteria foraging optimization (BFO) technique. The design of 2-D recursive filter is considered as a constrained optimization problem. The solution is obtained through the convergence of a biased random search using BFO. With the help of numerical illustrations, we(More)
This paper presents a new algorithm for LDA-based face recognition with selection of optimal principal components using E-coli Bacterial Foraging Strategy (EBFS). A GA-PCA algorithm has been reported to find optimal eigenvalues and corresponding eigenvectors in LDA. In their paper, a fitness function has been proposed to find the optimal eigenvectors to be(More)
In Wireless Sensor Networks (WSNs), sensor nodes are organized in a random manner. These sensor nodes are mainly deployed in physical environment to gather data and deliver the data to the destination wherever requires. Sensor nodes have limited computational capability, limited bandwidth, energy source and memory. The main challenge in data gathering is to(More)
Design a WiFi network infrastructure untrusted third parties (intruders and malicious internal nodes) control over routing is a challenging task to research directions for achieving security, scalability, flexibility and efficient communication over WiFi network communication. However, the flexibility control plane can be exploited to launch many types of(More)
Brain computer interfacing (BCI) plays an important role as an assistive device for various neural disorder people. In this paper, attempts have been made to interface thought process generated in photoplethysmography (PPG) with machine / computer. PPGs were collected by using PPG electrodes on fingertips corresponding to two types of brain activities,(More)
