To facilitate handover procedures in these scenarios, the 802.21 standard has been specified, providing Media Independent Handover (MIH) services allowing control and information gathering from different access interfaces. However, accessing these procedures requires the discovery of supporting nodes and their capabilities. This paper provides a description and performance comparison of different available MIH discovery schemes and proposes a novel local discovery procedure for automatically detecting link interfaces in MIH-enabled entities, showing by evaluation that its deployment increases performance and requires less information exchange.</p> 802.21 DHCP Discovery DNS IEEE 802.21 Wed, 08 Feb 2012 10:53:22 +0000 dcorujo 433 at https://atnog.av.it.pt
