Optimal Routing Path Selection to Improve Data Transmission and Lifetime of Wireless Sensor Network

Abstract The self-organizational ability of ad-hoc Wireless Sensor Networks (WSN) have led them to be the most popular choice. Despite significant advancements in Wireless Sensor Networks, efficient energy consumption in the network remains one of the most important research challenges. Clustering sensor nodes and organizing them hierarchically have proven to be an effective method to […]

FPAA Based Design of Assistive Listening Device for Hearing Disorders People

Abstract An assistive listening device (ALD) beyond hearing aids can assist individuals with hearing loss. The traditional aid is similar to a radio, which can be adjusted for volume. The hearing loss is not just a technical loss of volume. Hearing disorder looses sensitivity and reduces tolerance to certain sounds while diminishing sensitivity to others. […]
