Combined Sector and Channel Hopping Schemes for Efficient Rendezvous in Directional Antenna Cognitive Radio Networks

Algorithm 6

IPES-SCH generation algorithm.
Input: , Extended-ID , .
(1) Construct an IPES-SH sequence as explained in
Section 4.1.2.
(2) period = length(a).
(3)
(4) while  (not rendezvous)  do
(5) Current-sector = mod period.
(6) Steer the antenna to (Current-sector).
(7) BCL = [1 : n][Current-sector].
(8) if  (Current-sector is a P-sector)  then
(9) Construct a GCQ-CH sequence based on BCL.
(10) for () do
(11) Attempt rendezvous on channel .
(12) end for
(13) else
(14) Construct a GRQ-CH sequence based on BCL.
(15) for () do
(16) Attempt rendezvous on channel .
(17) end for
(18) end if
(19) .
