چکیده
|
Many existing medium access control protocols for cognitive radio wireless sensor networks waste bandwidth and suffer from delay because of the fixed channel negotiation period in the common control channel. in this paper,we propose a medium access control protocol for cognitive radio wireless sensor networks that adjusts the channel negotiation period based on network density. we simulate the proposed approach and compare it to the performance of the fixed channel negotiation period based approaches. the results show that the proposed approach efficiently utilizes white spaces and increases the aggregated goodput. copyright © 2016 gyanendra prasad joshi et al.
