<p><b>Abstract</b>—We consider the problem of selecting the <it>K</it>th smallest element of a set distributed among the sites of a communication network when the size of messages is bounded; that is, each message is a packet which contains at most <it>c</it> bits, where <it>c</it>≥ 1 is a constant.</p><p>A general selection algorithm using packets is presented and its packet complexity is analyzed. Its complexity is shown to be a significant improvement for a large range of packet sizes over the existing bounds. The proposed technique is then instanciated for specific classes of network topologies; the resulting bounds either match or improve the ones of existing solutions for a large range of values of the packet size. Furthermore, it is bit optimal in star networks.</p>
