Having an effective method for frequency assignment is very important in mobile communications. Artificial Immune Systems, a relatively new methodology for solving optimizationrelated problems, is investigated in this study to design a cellular frequency assignment model. In this framework, mobile hosts are allowed to continue interacting with the cells that they are currently in, even when the number of frequencies is insufficient. When the number of users increases, it is almost impossible to foresee future frequency demands in a cell. Often cellular networks are faced with insufficient frequencies in cells, whilst other cells have more frequencies available than they need. Our model works by allocating the unused frequencies from the cells with less demand to the overloaded cells. The model demonstrates that it manages to reuse the available free-conflict frequencies efficiently.

“…In [15], the authors proposed a hybrid channel allocation technique that incorporated channel borrowing technique, and queues are maintained during handoff strategy. The advantages of FCA in low traffic conditions and DCA in high traffic conditions are utilised, and a scheme is proposed in [16] which switches between FCA and DCA based on the traffic conditions. This process of switching is done using the concept of fuzzy logic.…”

Channel allocation plays an important role in next generation of wireless networks that require huge bandwidth support for various applications. It became very interesting and important research area in vehicular ad hoc network (VANET) as the channel allocation procedure needs to be efficient as the frequency of handoff is high because of the high mobility of the nodes. So, the authors propose a channel allocation algorithm that utilises channel reuse technique, channel borrowing process and the speed of the vehicle to reserve the channel for handoff calls to improve quality of service (QoS) in VANET. The calls are categorised as real-time originating calls, real-time handoff calls, non-real-time originating calls, non-real-time handoff calls and non-real-time transfer calls, and queue is maintained for non-real-time originating calls, which leads to nonreal-time transfer calls. The channel borrowing process is incorporated only for real-time originating calls and real-time handoff calls. The proposed system is modelled using two-dimensional Markov model. The proposed algorithm is simulated and evaluated in terms of QoS parameters as blocking probability, dropping probability and handoff latency. The performance is tested with varying system load, varying number of channels and is compared with legacy systems like cooperative reservation of service channels, CRaSCH, and a new dynamic channel allocation strategy which combines channel reservation with new call queuing, RQS.
