What is Wireless Battery Charger and its application

Day by day emerging technologies are making are life much easier. Invention of mobile phones has changed the life of the people rapidly. Their are many advancement in the mobile phones are made . Development is Growing , advancement is growing ,technologies are growing but still we do rely on the wired mobile battery charger. Every Companies phone has differently designed mobile charger. Hence we have to carry the battery charger every time with us. So,now the deal with this con of the wired mobile charger we came up with the idea of the wireless automatic mobile battery charger. In this system you just have to place your mobile on a table and your phone gets charged.This circuit mainly works on the principle of the mutual inductance. In this system power is transferred from the transmitter to the receiver wirelessly based on the principle of “inductive coupling”. Here the phenomenon of the mutual inductance is used in the system.i.e. If the current carrying conductor is placed near the other conductor, the current is induced in the other conductor because of the magnetic flux induced in the conductor. This induced magnetic flux induces voltage in the conducter.Hence both the conducters become inductively coupled. Switch on the supply. Connect the battery charger at the output of the circuit. Place the receiver coil near the transmitter coil .we can observe the charging of battery.
In this paper, the propose work use a new intrusion detection system specially designed for mobile ad hoc networks. The proposed scheme introduces a combination of a hybrid acknowledgement scheme as well as digital signature techniques. By adopting such techniques, the goal is to design and implement an efficient and secure intrusion detection system called EAACK (Enhanced Adaptive ACKnowledgement) for mobile ad hoc networks that is capable of detecting misbehaving nodes in mobile ad hoc networks and address many challenges in this area. EAACK is designed based on the Digital signature Algorithm (DSA). This technique has drawback due to the collusions of packets and distribution of keys between nodes becomes overhead. The propose work introduce a new alternate technique by developing a key management scheme and a secure routing protocol.
