To provide a communication terminal and a communication network for stabilizing communication, avoiding radio interference, and effectively using network resources.
The communication terminal is configured with a plurality of communication terminals each provided with: a communication section 1 for transmitting/receiving packets; a number of hop storage section 4 for storing the number of hops between each of other terminals and its own terminal; a packet analyzer section 2A that sets a number of the number of hops n or over corresponding to the shortest path to be a hop range number n+a between both the terminals on the basis of the number of hops between the destination terminal (terminal D) and its own terminal stored in the number of hop storage section 4 when its own terminal is the source terminal (terminal S) and analyzes the terminals S, D and the n+a on the basis of the received packet when its own terminal is a relay terminal, sums both the number of hops between the terminal S and its own terminal and between the terminal D and its own terminal in the number of hop storage section 4 to obtain the number of hops h, and relays and transmits the packet only in the case of h≤n+a; and a packet generating section 3 for adding the set n+a to the packet to generate a transmission packet when its own terminal is the terminal S.
