In some restrictive environments, such as sensor networks, each sensor submits the newest information to the server, every message must be authenticated to immune forgery and replay attacks. But the regular signatures need to be saved and verified individually, which will heavily add the costs of the computation, storage and communication
than the plain text mode in the constraint devices. Aggregate signature (AS) makes towards solving the above problem because anyone can aggregate $n$ individual signatures on $n$ distinct messages which are signed by $n$ distinct signers, into a single compact signature $\sigma$.
