Abstract
- This paper elaborates on the suboptimal greedy algorithm for target channel sequence selection as presented by Wang <bold>et al.</bold> in the paper, “Optimal Target Channel Sequence Design for Multiple Spectrum Handoffs in Cognitive Radio Networks,” <bold>IEEE Transactions on Communications</bold>, vol. 60, no. 9, pp. 2444–2455, September 2012. They claimed that the greedy algorithm requires comparing six target channel sequences. We prove that only five target channel sequences comparisons are sufficient. Hence, we present a modified algorithm and test it with a set of numerical results. It appears that the new algorithm reduces the processing time compared to the original one especially for a network with a large number of candidate channels. [ABSTRACT FROM PUBLISHER]
