Dynamic Spectrum Access Strategy for Multi-Channel Cognitive Radio Networks
In this paper, we present a dynamic spectrum access strategy to reduce the average overall system time of secondary users (SUs) in multi-channel cognitive radio networks. Before transmitting a packet, SU senses the spectrum environment. If there are free channels in the system, SU randomly selects one for transmitting. If all the channels are busy, we consider a probability-based spectrum selec...
متن کاملOpportunistic Spectrum Access in Cognitive Radio Ad Hoc Networks
Cognitive Radio (CR) technology is envisaged to solve the problems in wireless networks resulting from the limited available spectrum and the inefficiency in the spectrum usage by exploiting the existing wireless spectrum opportunistically. CR networks, equipped with the intrinsic capabilities of the cognitive radio, will provide an ultimate spectrum aware communication paradigm in wireless com...
متن کاملDistributed dynamic channel access scheduling for ad hoc networks
Three types of collision-free channel access protocols for ad hoc networks are presented. These protocols are derived from a novel approach to contention resolution that allows contending entities to elect one or multiple winners for channel access in any given contention context (e.g., a time slot) in a distributed fashion. In multihop wireless networks, the only required information for each ...
متن کاملThe Cognitive Ad-hoc Network Spectrum - Routing Selection Method
Based on cognitive self-organizing network transmission delay larger and larger interference to primary user receiver problem, put forward a method of spectrum joint routing selection, this method is effective to consider the transmission delay and the main user interference at the receiving end, mainly from < 1 > bandwidth available probability; < 2 > sent via link the number of bits of varian...
متن کاملA Sensing Contribution-based Two-layer Game for Channel Selection and Spectrum Access in Cognitive Radio Ad-hoc Networks
In cognitive radio (CR) networks, the secondary users (SUs) sense the spectrum licensed to the primary users (PUs) to identify and possibly transmit over temporarily unoccupied channels. Cooperative sensing was proposed to improve the sensing accuracy, but in heterogeneous scenarios SUs do not contribute equally to the cooperative sensing result because they experience different received PU sig...
