A Probabilistic Spray-and-Wait Routing Algorithm Based on Node Interest Preference in Delay Tolerant Networks

Algorithm 1

Pseudocode for buffer management.

Input:

  the node that is ready to receive the message

 , number of copies of that need to forward to

 , set of messages need to forward to

1: ifthen

2:  

3:  for each message in do

4:   if

5:   then

6:    delete the messages with smallest in

     until has enough buffer size to receive

7:   end if

8:    forward to

9:  end for

10: end if
