Abstract.
We consider a basic problem in the general data streaming model, namely, to estimate
a vector f 2 Zn that is arbitrarily updated (i.e., incremented or decremented) coordinatewise.
The estimate ˆ f 2 Zn must satisfy k ˆ f − fk1 _ _kfk1, that is, 8i (| ˆ fi −fi| _ _kfk1). It is
known to have ˜O(_−1) randomized space upper bound , (_−1 log(_n)) space lower bound
and deterministic space upper bound of ˜(_−2) bits.1 We show that any deterministic
algorithm for this problem requires space (_−2(logkfk1)) ....etc

Abstract

This is paper presents a complete view on working of payment transaction by E-cash. Cryptography used in this process finds the double spending and forgery of E-cash which is nothing but digital information. The digital information specified as E-cash contains the identity of buyer. Bank maintains all information involved in E-cash notes for every user.

The process of transaction involves three participants i.e, bank (who signs E-cash notes),buyer (who uses E-cash),seller(who deposits the notes). The cryptograph ....etc

The transmission energy required for a wireless communication increases superlinearly with the communication distance. In a mobile wireless network, nodal movement can be exploited to greatly reduce the energy required by postponing communication until the sender moves close to a target receiver, subject to application deadline constraints. In this paper, we characterize the fundamental performance limit, namely the lower bound expected communication distance, achievable by any postponement algorithm within given deadline constraints. Our analy ....etc
