Channel allocation strategies for hybrid DCNs In [11] , the authors propose a Genetic-based approach that tackles the channel allocation problem while involving traffic demands. This paper presents a hybrid channel allocation notification to the central pool on each channel request that cannot be satisfied locally at the base … HDCN enables high throughput wireless (IEEE 802.11ad) and wired (IEEE 802.3) transmissions. endobj In this paper attempts are made to reduce call-blocking probability by designing hybrid channel allocation (HCA) which is the combination of fixed channel allocation (FCA) and dynamic channel allocation (DCA). A simulation result shows that HCA scheme significantly reduces call-blocking probability in hotspot scenario and compared with cold-spot cell. radio spectrum 404 - 410, telecommunication traffic : +1 419 530 6002; fax: +1 419 530 8146. fixed channel allocation The use of available channels has been shown to improve the system capacity. When a user make a call then first fixed set of channels are utilized but if all the fixed sets are busy then dynamic sets are used. The numerical results show that the proposed hybrid algorithm is more efficient than other approaches, specifically, in comparison with methods without a borrowing capability for new calls and those without a reserved buffer priority for handoff calls. When a User makes a call request then Base Station(BS) send that request to the Mobile Station Center(MSC) for the allocation of channels or voice channels.
