Background:
In traditional networks, nodes drop messages in order to free up enough space for buffer
optimization. However, keeping messages alive until it reaches its destination is crucial in Opportunistic Networks.
Therefore, this paper proposes an Acumen Message Drop scheme (AMD) that consider the impact of the message drop
decision on data dissemination performance.
Methods:
In order to achieve this goal, AMD drops the message based on the following considerations: the estimated time
of message's arrival to its destination, message time to live, message transmission time, and the waiting time of the
message in the queue. AMD scheme works as a plug-in in any routing protocol.
Results:
Performance evaluation shows that the integration of the proposed scheme with the PRoPHET routing protocol
may increase efficiency by up to 80%, while if integrated with Epidemic routing protocol, efficiency increases by up to
35%. Moreover, the proposed system significantly increases performance in the case of networks with limited resources.
Conclusion:
To the best of our knowledge, most of the previous works did not address the issue of formulating the
message drop decision in the non-social stateless opportunistic networks without affecting performance.
