Survivability Analysis of VMIMO link in Multi-hop Wireless Network
Résumé
Cooperative diversity or virtual antenna arrays enables transmission range extension and provides performance enhancements in wireless Multi-hop relay networks, when compared with relaying non cooperative diversity based schemes. Moreover Cooperative diversity allows better reliability to link failure and lead to a more efficient transmission that is of particular interest in mobile environment. In this paper we propose a quantitative analysis and survivability evaluation of a virtual antenna array link (VMIMO) subject to failures in a multi-hop wireless network using cooperative diversity and assuming Markovian properties. The analysis is model based and enables to assess and to quantify survivability metrics such as ELF end EDF.
