PROBLEM TO BE SOLVED: To provide a network jamming attack detection device capable of achieving a highly reliable sensor information communication.SOLUTION: A PDR calculation section 7 calculates a packet arrival rate of a route between target terminals as well as a packet arrival rate of another route between the target terminals. When the difference between the former packet arrival rate and the latter one of another route between the target terminals exceeds a threshold value, a NJA detection section 8 determines that the route between the target terminals is under influence of a network jamming attack. |
