Efficient MAC Protocol for Heterogeneous Cellular Networks ( HC - MAC )
This papers details the efficient MAC protocol for heterogeneous Cellular network. Present 3G-cellular radio access network cannot support many concurrent high data rate unicast (or) flows due to limited radio resources. We proposed Mac protocol for heterogeneous cellular network (HC-MAC). The heterogeneous network uses a proprietary protocol for communication within the network and TCP/IP for ...
متن کاملAdaptive power-controlled MAC protocols for improved throughput in hardware-constrained cognitive radio networks
Cognitive radios (CRs) are emerging as a promising technology to enhance spectrum utilization through opportunistic on-demand access. Many MAC protocols for cognitive radio networks (CRNs) have been designed assuming multiple transceivers per CR user. However, in practice, such an assumption comes at the cost of extra hardware. In this paper, we address the problem of assigning channels to CR t...
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 کاملHardware Implementation of MAC Unit
Digital signal processing (DSP) applications, the critical operations usually involve many multiplications and/or accumulations. So, for real time signal processing applications, high throughput multiplier–accumulator (MAC) is always a key element to achieve a high-performance digital signal processing application. This is because speed and throughput rate are always the concerns of digital sig...
متن کاملA Cooperative MAC with Efficient Spectrum Sensing Algorithm for Distributed Opportunistic Spectrum Networks
The spectrum scarcity has led to rethink in the current frequency spectrum usage and develop a new concept of wireless networking. Opportunistic Spectrum Networks (OSNs) have been considered as a promising solution to the problem of spectrum shortage. In this paper, in order to compensate for the need of complex hardware, a novel and efficient Medium Access Control (MAC) framework that integrat...
