Conventional methods used in batch signature verification do not distinguish between static node signature verification and mobile node signature verification. Static nodes rarely face energy expenditure problem, but energy conservation is given a critical importance in mobile nodes. In this paper, we propose a new scheme for energy conservation at mobile receiver. Mobile receiver requests sender to modify the batch size based on the available energy at the receiver; when energy at the mobile receiver has reached particular threshold1, then sender is informed to reduce the batch size to half of the original batch size, which decreases the energy utilized by the mobile receiver for batch signature verification. When the energy at the mobile receiver has reached 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 which occurs when batches do not reach mobile receiver.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
