Implementing IEEE 802.11b/g wireless Local Area Networks
... Two types or modes of WLANs exist; the technology that provides connectivity to the infrastructure network and the technology that provides the connectivity of one device to another or an adhoc network. This is also depicted in Figure 1.1 [3-5]. IEEE 802.11-based WLANs work in both modes. WLANs do n ...

Security Signaling During Handovers
