A novel spectrum handoff switching decision scheme for improved performance of secondary users in cognitive radio network

Sudipta Dey, Iti Saha Misra

International Journal of Communication Systems > 36 > 4 > n/a - n/a

Spectrum handoff (SH) in the cognitive radio network (CRN) is considered as a key challenging area to enhance the performance of secondary users (SUs) in CRN. If the primary user is detected, the SU may pause and stay on the same channel or may perform SH to another idle channel. An accurate and precise handoff decision improves the overall throughput and quality of experience of end‐users. In this...

Performance Analysis of a UMTS Cell with Underlying Tunnel-WLANs

Sibaram Khara, Iti Saha Misra, Debashis Saha

Lecture Notes in Computer Science > Distributed Computing and Networking > Wireless Networks > 389-394

Users’ preference of WLAN-access has potential effect on the performance of a UMTS cell with underlying WLANs. In the models with complementary-WLANs, the hybrid users (i.e., UMTS users having WLAN privileges) are permitted to access WLAN only in the event of blocking of their data-requests in UMTS. So, a user sometimes misses the high speed data services of WLAN because he/she does not access WLAN...
