Prolonging the lifetime of a sensor node powered by battery in both homogeneous and heterogeneous wireless sensor networks is a massive challenging area of research now-a-days. To achieve this target many research works including low energy adaptive clustering hierarchy (LEACH) and its variants use clustering techniques to reduce energy spent by keeping most of the nodes in sleeping mode whenever...
Pilot wire differential protection is one of the most common methods for protecting short transmission lines. The conventional protection scheme has drawbacks, such as malfunction due to line disconnection and limited line length. A laboratory investigation of transmission line protection using Wireless Fidelity (Wi-Fi) communication protocol for data sharing between the relays located at the two...
A protection scheme for parallel transmission lines protection using wireless fidelity (Wi-Fi) protocol is introduced in this paper. The measured data at both ends can be exchanged through Wi-Fi protocol. In such a case, the onsite measured data and the transmitted data from remote end will be available for each relay. A protection technique is used for manipulating the data. Then a final decision...
