In-sequence molecule delivery over an aqueous medium

Molecular communication takes place in a challenging environment that is characterized by large latency and jitter. In its basic form, a molecule transmitted by a sender is affected by thermal noise and walks randomly in an aqueous medium. Because of the random nature, the transmitted molecule may not reach the receiver, or arrive at the receiver in random order in cases where multiple molecules are transmitted by the sender. In this paper, we discuss approaches for increasing the chance of in-sequence molecule delivery in aqueous environments. Three classes of approaches (sender, receiver, and environment-oriented approaches) are designed and the probability of in-sequence molecule delivery is investigated.
