Abstract:
1. A communication system, comprising: a core node that connects to a backbone network; and a plurality of slave nodes that connect to the core node with wireless communication directly or via another slave node, wherein the core node transmits, to one of the slave nodes, a reset routing packet for instructing the slave node to initialize a communication route from the core node to the slave node itself, and afterwards, a plurality of normal routing packets for instructing the slave node to construct a communication route from the core node to the slave node itself; the slave node includes: the route making processing unit includes: the reception power evaluation unit, if n equals to or is larger than two, calculates a reception power evaluation value which is an evaluation value of a reception power between the slave node itself and the transmission source node, based not only on a reception power of the n-th normal routing packet received but also on a part of or all of reception power of the reset routing packet and/or the normal routing packet separately received.
