Secure ubiquitous connectivity in hybrid multipath wireless ad hoc network

With the increasing demand of ubiquitous computing, the interconnection of mobile ad hoc network (MANET) to internet is also getting attractive, which is so-called hybrid or connected MANET. Further, as the use of multipath ad hoc routing protocols is favorable in many application, hybrid multipath MANET, which is a MANET with multiple routes to the Internet, will also grow. Security issues in hybrid MANET, however, are still a challenging task. This paper addresses security issues related to Internet connectivity and ad hoc routing. In this paper, we present secure architecture framework for ubiquitous connectivity in hybrid multipath MANET that provides secure FA discovery as well as a secure Mobile IP registration for MN. We provide security and performance analysis for the proposed framework, and compare it with the exisitng schemes. It shows that the proposed framework is more effective than the existing schemes in terms of various parameters.
