In this paper we propose an online, reward-based routing and spectrum assignment (RSA) method for multirate flex-grid optical networks. The method, denoted as MDP-RSA, is derived from a flex-grid optical link model based on the theory of Markov decision processes. Assuming that connections arrive randomly offering a reward to the system, the objective is to take the best decision on admission, routing...
In order to provide communication service in the Intermittently Connected Mobile Networks (ICMN) where there is only intermittent connectivity between mobile nodes, a variety of epidemic-style routing algorithms have been proposed to achieve high message delivery probability. However, current works do not address the realistic environment that a message is split into multi frames to be transmitted...
We derive the Neyman-Pearson error exponent for the detection of Gauss-Markov signals using randomly spaced sensors. We assume that the sensor spacings, d1,d2,..., are drawn independently from a common density fd(.), and we treat both stationary and nonstationary Markov models. Error exponents are evaluated using specialized forms of the strong law of large numbers, and are seen to take on algebraically...
