An optimized model for interference and traffic aware topology control in WSNs

Energy conservation and interference reduction are the two important goals of any topology control algorithm in wireless multi-hop sensor networks, but impacts of traffic on interference have been largely ignored in mostly all previous works on topology control. Inspired by this challenge, we set out to investigate the impact of traffic load on nodes´ energy consumption and having demonstrated its significance. Also, a relation between traffic and interference was established by using collision numbers. We then went on to formulate an optimization method for our topology control with the goal of minimizing the maximum power consumption among network´s nodes.
