Resumo


With the increasing amount of mobile interfaces combining different kinds of access technologies, ranging from Wi-Fi to 3G and LTE, the integration of flexible and mediaindependent link control mechanisms becomes of paramount importance. By employing an abstract way of obtaining access link status information and exercising control over the network interface operations, these control mechanisms become able to optimize device connectivity and network attachment. This paper presents EMICOM, an Enhanced Media Independent COnnection Manager framework where a GNU/Linux Network Manager and Link Service Access Points for the IEEE 802.3 and 802.11technologies were implemented and integrated through crosslayer Media Independent Handover (MIH) mechanisms from the IEEE 802.21 standard. Through an open-source implementation of the framework, the (MIH) command set capabilities are extended, allowing the support of network association and authentication, as well as Layer 3 services such as IP configuration, providing a generic solution for optimal network connectivity management.
