In wireless networks, continuous connectivity which allows user mobility and maintains the secured network utilization is one of the most important requirements. WLANS are widely used in business, governments, education and public. In order to establish wireless LAN with continuous connectivity, the authors need to employ additional mechanisms like IAPP, LBAC etc. In this paper, they used the concept of proactive context caching for LBAC-IAPP WLAN to provide continuous connectivity to secure wireless systems. In PCC the selected neighbouring base stations exchange link quality information of the mobile node through distributed system and the information stored in to the cache memory of mobile stations.
