Center node: "threshold phenomena for interference with randomly placed sensors"
  Abstract: Assume $n$ sensors are initially placed on the half-infinite interval $[0,\infty)$ according to Poisson process with arrival rate $n.$ Let $s \ge 0$ be a given real number. We are allowed to move the sensors on the line, so as that no two sensors are placed at distance less than $s.$ When a sensor is displaced a distance equal to $|m(i)|$ the cost of movement is proportional to some (fixed) power $a>0$ of the $|m(i)|$ distance traveled. As cost measure for the displacement of the team of sensors we consider the $a$-total movement defined as the sum $M_a:=\sum_{i=1}^n |m(i)|^a,$ for some constans $a>0.$ In this paper we study tradeoffs between interference value $s$ and the expected minum $a$-total movement.
