Abstract
The Great East Japan Earthquake caused many casualties and radiation
contamination from the Fukushima nuclear power plant, and many problems still
remain in the disaster area. The communication network was severely affected by
the earthquake. The network disconnection greatly delayed the rescue work and
isolated many residential areas. This lack of robust network connection has
become one of the major topics for any discussion of a Disaster Information
Network System. This paper proposes a Never Die Network (NDN) which will
consist of a Cognitive Wireless Network (CWN) and a Satellite Network. The best
possible wireless links and routes are selected out of multiple wireless
networks. This proposal, first of all, puts forward a cognition cycle which has
a continuous network and user changing environment. Secondly, the optimal link
selection will adapt the extended Analytic Hierarchy Process (AHP) method by a
change of network environment and user policy during a disaster. Then, if the
network environment or user environment can be changed, a proper route
selection method can be conducted by the proposed extended Ad Hoc On-Demand Distance
Vector (AODV) method with Min-Max AHP values. The simulation described in this
paper contains an evaluation of the proposed methods by comparing a single
ordinal wireless network system and a CWN for the disaster situations. The
probable effectiveness of the proposed methods is discussed in this paper.
