Sector coded transmission protocol for Cognitive Radio Networks
Vinayak Abrol, Pulkit Sharma · 2012
In practical Cognitive Radio Networks for Mobile Communication cluster based topology is used to increase spectrum detection performance. The energy of Head Node depletes faster than the member nodes and thus rotation of cluster head is needed for the energy efficiency of Cognitive Radio Networks. The level of hierarchy is increased in this approach by introducing a Super Node which communicates between the Head Nodes and the BTS. In this paper, a new scheme called Sector Coded Transmission (SCT) is proposed in which the Head Nodes are rotating with a two level hierarchy.
