Infrastructured network consists of fixed base stations while communications take place using technique handoff. It connects with new base station and start communication when mobile goes out of range of one base station. Advantages over ad-hoc networks are efficiently utilized network resources and single-hop routes, results in: lower delay and loss and higher data rates examples: wireless LANs, paging systems, and cellular phone systems. Base station coordination in infrastructure-based networks provides a centralized control mechanism for transmission scheduling, dynamic resource allocation, power control, and handoff .Wireless networks are an emerging new technology that allow user to access information and services electronically, regardless of their geographic position.
