This paper describes a cooperative MANET protocol dedicated to intelligent transport systems, named CIVIC (Communication Inter Véhicule Intelligente et Coopérative). The CIVIC protocol is an auto-configuration inter-vehicle communication protocol, which supports adhoc and infrastructure networks, contains reactive and proactive routing components, and adapts different wireless standards. It is ...

A new bound is proposed relating the average cost sub-optimality of a myopic policy to its differential cost error. The bound is an expectation over the stationary distribution for this policy. For small queueing networks, we compute or approximate the distribution using the matrix analytic method and numerically test the bound. Product form approximations to the stationary distribution are als...

The paper deals with the ergodicity of deterministic zero-sum differential games with longtime-average cost. Some new sufficient conditions are given, as well as a class of games that are not ergodic. In particular, we settle the issue of ergodicity for the simple games whose associated Isaacs equation is a convex-concave eikonal equation. Introduction We consider a nonlinear system in R contro...

Cloud computing as a developing technology trend is estimated to reshape the advances in info technology. In a cost-efficient cloud infrastructure, a user can tolerate a certain degree of interval while retrieving info from the cloud to decrease costs. In this paper, we address two major issues in such an environment: secrecy and efficiency. We first review a secretive keyword based file recove...

This paper shows that partial differential equations may be a possible area of application of mathematical programming. The solution of Laplace's equation with Neumann's condition is shown to be a minimum cost network flow problem with cost proportional to the arc flow. An algorithm of solving minimum quadratic cost network flow is given.
