Design and Analysis of an OSA-BR MAC protocol for Cognitive Radio Ad Hoc Networks
Cognitive Radio (CR) is a new communication network paradigm introduced to solve the problems of spectrum scarcity and inefficient spectrum usage. Basically, it allows the Secondary Users (SUs) to utilize the Licensed Channels (LCs) of the Primary Users (PUs) in an opportunistic manner without causing any harmful interference to the PUs. However, there are many challenges associated with cognit...
متن کاملAn Efficient MAC Protocol for Cognitive Radio Networks
Energy efficiency Abstract: At present cognitive radio networks allow moderate sharing of the radio spectrum without causing any harmful interference to licensed users. In this paper, we propose a new efficient medium access control (MAC) protocol that aims at improving the coexistence of licensed primary users (PU’s) & unlicensed secondary users (SU’s) in cognitive radio networks. However, the...
متن کاملA Hybrid MAC Protocol for Cognitive Radio Ad Hoc Networks
In cognitive radio networks, secondary users exchange control information to utilize the available channels efficiently, to maintain connectivity, to negotiate for data communication such as sender-receiver handshakes, for neighbor discovery etc. This task is not trivial in cognitive radio networks due to the dynamic nature of network environment. Generally, this problem is tackled by using two...
متن کاملMultichannel MAC Protocol with Discontiguous-OFDM for Cognitive Radio Networks
Medium access control (MAC) protocols in a cognitive radio network (CRN) are required to increase spectral efficiency and achieve high data rate for secondary users (SUs). Many MAC protocols use a single control channel with a bottleneck problem. In this paper, we propose a multichannel MAC protocol using dicontiguous orthogonal frequency division multiplexing (D-OFDM) in a CRN. Since D-OFDM te...
متن کاملA Sensing Error Aware MAC Protocol for Cognitive Radio Networks
Cognitive radios (CR) are intelligent radio devices that can sense the radio environment and adapt to changes in the radio environment. Spectrum sensing and spectrum access are the two key CR functions. In this paper, we present a spectrum sensing error aware MAC protocol for a CR network collocated with multiple primary networks. We explicitly consider both types of sensing errors in the CR MA...
