DRANs: Resilient Disaster Recovery Access Networks

Wireless access network is an appropriate solution to provide Internet connection to users in disasters where communication infrastructures might completely be damaged. However, existing researches commonly focus on separate issues, given strong requisite assumptions. Basically, those assumptions could not be satisfied in harsh environments like in disasters. In addition, a combination of those separate research aspects into an integrated system has not been discussed. This paper thoroughly analyzes current states of existing wireless access network technologies by which suitable solutions for resilient disaster recovery access networks (DRANs) are proposed. Moreover, a novel wireless multihop access network virtualization (WMANV) approach to resilient DRANs is proposed. The feasibility of the proposed approach is verified using experimental evaluations.
