This paper considers central issues of distributed computing in a mobile environment. Its aim is to light on the first brick of a common view for mobile systems. The authors propose a distributed algorithm for solving the h-out of-k mutual exclusion problem for ad hoc mobile networks. The h-out of-k mutual exclusion problem is also known one the h-out of-k resource allocution problem. The distributed computing area includes henceforth mobile systems (i.e., cellular and ad-hoc networks, peer-to-peer systems, mobile virtual reality and cooperative robotics).
