Background & Objective: Underwater acoustic channels suffer from multipath, attenuation, noise, frequency selectivity and Doppler effect. Finding efficient methods to communicate over such very poor quality and high latency channels has been a challenge. A multipath underwater acoustic channel can be seen as a sparse system, whose impulse response contains many zeroes and very few large coefficients. The underwate Read More

Background & Objective: Present wireless generation i.e. 4G is facing challenges like interference management, load sharing and increased capacity demands. Researchers all over the globe are working on to overcome these challenges by introducing 5G in the market. The introduction of relays in Device to Device (D2D) communication and small cell access point (SCA) has fulfilled the issues of interference management Read More

Background & Objective: The presented design attempt of building an advanced prosthetic lower limb has a vast requirement in these days to connect paralytic patients and elderly people with the external environment for a better lifestyle. The Recordings of Electromyography (EMG) patterns and other data analysis of the muscle signals has lightened the path of technology to a wide range of studies and experiments i Read More

Background & Objective: Several studies have revealed that mobile sinks help in extending the lifetime of Wireless Sensor Networks (WSNs) by minimizing multihop transmissions. However, prolonging lifetime of WSNs that require all sensed information to be collected within a time limit involves considerable challenges. A proposed framework to gather data in such WSNs is to combine multihop transmissions with a mobil Read More

Background & Objective: With the rapid improvement in mobile communication technology, the query processing has gained a huge interest from the mobile users. But the requirement of high efficiency and high quality service in query processing is still increasing. A query processing scheme in hybrid wireless network is proposed in the present work. Method: In the proposed query processing scheme, normal nodes generate Read More

Background & Objective: Vanet is ad-hoc or temporary network that supports vehicle to vehicle or vehicle to infrastructure communication. Nowadays due to the exponential rise in road traffic and accidents, it is necessary to have information about vehicle position, speed, direction, lane etc. that aware us from traffic, road condition etc. to avoid accidents. Research has been going on in the field of traffic congestion probl Read More
