what is channel assignment in wireless communication

Gateway to the 21st Century (Cat. The design of a wireless local area network (WLAN) has an important issue of determining the optimal placement of access points (AP) and assignment of channels to them. : Large-Scale Real-World Telecommunication Problems Using a Grid-Based Genetic Algorithm. 2848–2851 (2009), Parsapoor, M., Bilstrup, U.: Ant colony optimization for channel assignment problem in a clustered mobile ad hoc network. • Dynamic channel assignment (DCA): no pre-allocation.

Communications, Network and System Sciences. WLAN services in the outdoor as well as indoor environments should be designed in order to achieve the maximum coverage and throughput. Channel assignment is a challenging issue for multi-radio multi-channel wireless networks, especially in a competing environment. This paper investigates channel assignment for selfish nodes in a heterogeneous scenario, in which nodes may have different QoS requirements and thus compete for different channels with unequal bandwidth.

Based on some observations on the radio number distribution of NE, we propose a two-stage optimization algorithm to achieve an optimal channel assignment. Engineering Optimization.

Since multiple NEs may exist in this game, it is natural to choose the NE that maximizes the network utility, i.e., the sum of node utilities. The design of a wireless local area network (WLAN) has an important issue of determining the optimal placement of access points (AP) and assignment of channels to them.

IEEE Trans. : FAsoft: A system for discrete channel frequency assignment. To provide the maximum coverage for WLAN service areas, AP should be installed … The interaction among nodes is formulated as a non-cooperative Multi-radio Channel Assignment Game (MCAG), where Nash Equilibrium (NE) corresponds to a stable channel assignment outcome from which no individual node has the incentive to deviate.
