Classification of wireless networks ● Cellular Networks Organized base stations that are regularly placed Mobiles communicate only with base stations Wireless lans Less organized access points with which mobile nodes communicate Ad hoc/Multi-hop networks No infrastructure; nodes potentially move and network dynamically changes Sensor networks application specific; mobility is limited (perhaps to selected subset of nodes); tiny nodes that are resource and energy constrainedClassification of Wireless Networks • Cellular Networks – Organized, base stations that are regularly placed. Mobiles communicate only with base stations • Wireless LANs – Less organized; access points with which mobile nodes communicate • Ad hoc/Multi-hop networks – No infrastructure; nodes potentially move and network dynamically changes • Sensor Networks – application specific; mobility is limited (perhaps to selected subset of nodes); tiny nodes that are resource and energy constrained
