简介
Resource control is a method for congestion control and avoidance in Wireless Sensor Networks (WSNs) that has attracted a lot of attention lately. Employing a resource control method implies that in case of congestion, instead of controlling the data rate of the sources (traffic control method), the network takes advantage of the redundant deployment of the wireless sensor nodes and employs a number of them, in order to create alternative paths from the congested area to the sink. A critical decision that must be taken by resource control algorithms, is which node is the most appropriate to become the root of the alternative path and what route the alternative path will follow. A wrong decision is possible to lead to congestion in an after point of the network. In this study we investigate whether the adoption of an aerodynamic flow model could provide an efficient solution to this critical routing issue. In particular, we study the spiral downwards movement of the vortex elements below the rotor plane of a helicopter during forward flight, and employ it in order to study the possible routing attitude in congested WSNs.
