Ccef to Extend Network Lifetime in Wsns

The pervasive application of wireless sensor networks (WNSs) is challenged by the scarce energy constraints of sensor nodes. En-route filtering schemes, especially commutative cipher based en-route filtering (CCEF) can saves energy with better filtering capacity. However, this approach suffer from fixed paths and inefficient underlying routing designed for ad-hoc networks. Moreover, with decrea...

α-Coverage to extend network lifetime on wireless sensor networks

An important problem in the context of wireless sensor networks is the Maximum Network Lifetime Problem (MLP): find a collection of subset of sensors (cover) each covering the whole set of targets and assign them an activation time so that network lifetime is maximized. In this paper we consider a variant of MLP, where we allow each cover to neglect a certain fraction (1−α) of the targets. We a...

Ion-Trap Quantum Computation

Quantum computation requires a very special physical environment. Numerous operations must be performed on the quantum states of the qubits (or quantum bits) before those states decohere, or lose the interlocking phase relationships that give quantum computation its power. Thought to be an unavoidable outcome of the interaction between the quantum state and the environment, decoherence threaten...
