Multicast Authentication Scheme for Energy Conservation

Conventional methods used in batch signature verification not distinguished between static node signature verification and mobile node signature verification. Static nodes rarely faces energy expenditure problem but energy conservation is given a critical importance in mobile nodes. In this thesis we propose a new scheme for energy conservation at mobile receiver. Mobile receiver request sender to modify the batch size based on the available energy at the receiver, when energy at the mobile receiver has reached to particular threshold1 than sender is informed to reduce the batch size to half of the original bath size, which decreases the energy utilized by the mobile receiver for batch signature verification. When the energy at the mobile receiver has reached to threshold2 then sender is informed to stop batch transmission till further request from mobile receiver for batch transmission of new batch size, this reduces packet loss occurs when batches are not reached to mobile receiver.
