Seleção de Gateways Móveis em Redes Heterogêneas Sem Fio com Múltiplos Saltos

Fabrício LobatoOtávio Rodrigues Jr.Kelvin Lopes Dias

One of the research challenges for 4G wireless is the development of mobile gateway selection mechanisms for Heterogeneous Multi-hop Wireless Networks (HMWN). Currently, there are only fixed gateway selection mechanisms for HMWN. In this paper we proposed an improvement to an existing HMWN architecture by including a new index based on the gateway mobility prediction in order to select the best connectivity. We compare the modified architecture with the original one considering mobile gateways with various velocities. Simulations results demonstrate that our proposal outperforms the original scheme in terms of the evaluated metrics.
