This paper presents a quorum sensing algorithm to coordinate nanorobots and avoid congestion in blood vessels. In the algorithm, nanorobots use a chemical signal like autoinducer of bacteria to estimate the number of nanorobots in target site. And a method to determine the maximum value of nanorobots number in different vessels depending on vessel diameter is proposed. Simulations have been conducted to evaluate the effectiveness of the algorithm in a local field of blood vessels.
