Table 1

Two-dimensional table of probability maintained by nodes.

Current node	Destination node	Probability value of historical message delivery	Node's historical encounter duration	Node's historical disconnection duration
A	B	P(A,B)old	T(A,B)old	TU(A,B)old
A	C	P(A,C)old	T(A,C)old	TU(A,C)old
A	D	P(A,D)old	T(A,D)old	TU(A,D)old
