This paper explores the methods of the transmit power allocation of a multi-hop cognitive radio networks (CRM) with linear topology. Was investigated a scenario in which CRM operates in parallel with the primary network (tenant of the current licensed frequency band), with condition of limited to a certain threshold level the interference that causing the CRN for the primary network. In multi-hop CRM a information sent by the source node on the path to the destination node takes several hops from node to node. During each retransmission the information is decoded and sent to the next node. It is assumed that the transmitted signals may also reach the neighboring node, thereby creating interference for them. In this paper we show that for linear CRM optimal power allocation is achieved when equality of capacities of all intermediate channels and restrictions on interference most noisy member of the primary system, performed by with equality. |
