A Multisource Situation Information Fusion Method Based on Dynamic Evidence Combination

Algorithm 1

Classification based on spatial features (CSF).

	Input: original alert information
	Output: classification result
(1)	Begin
(2)	n = AlertsNum(alerts); //alert numbers
(3)	q = 0; //set the counter
(4)	While (q < n)
(5)	IP = GetIP(alerts); //get IP in alerts
(6)	If IP in [10.0.0.0 10.255.255.255]
(7)	return class A1;
(8)	Else if IP in [128.0.0.1 191.255.255.254]
(9)	return class A2;
(10)	Else if IP in [192.0.0.1—223.255.255.254]
(11)	return class A3;
(12)	Else if IP in [224.0.0.1—239.255.255.254]
(13)	return class A4;
(14)	Else
(15)	return class A0;
(16)	End if
(17)	q = q + 1;
(18)	End while
(19)	End
