LTE in Unlicensed band (LTE-U) has gained intensive attention recently due to its capability to offload mobile data to unlicensed bands. In order to use unlicensed band, LTE-U has to coexist with WiFi - another wireless technology that operates in unlicensed bands. This coexistence is riddled with several challenges as these technologies use different core networks, backhauls and deployment plans...
LTE-A as a cellular technology has gained tremendous importance in recent years due to its high data-rates and improved data access for mobile devices. Recently, utilizing the unlicensed band as a supplementary band for LTE-A is being considered to expand the capacity of mobile systems. License-assisted access using LTE (LAA-LTE) will thus operate in the unlicensed band, and will operate in a spectrum...
In this paper, we introduce the concept of "route robustness" for path selection in multi-hop cognitive radio networks. We demonstrate that the aggregate throughput and the robustness of routes determined by the proposed route selection strategy are superior to existing rate-based selection strategies. The rationale behind our approach is to guarantee a basic level of robustness for a set...
In this paper, we introduce the concept of "route robustness" for path selection in multi-hop cognitive radio networks. We demonstrate that the aggregate throughput and robustness for routes determined by the introduced route robustness selection strategy are much better than those determined by other selection strategies as proposed in existing work. The rationale behind our approach is...
