Secure Routing in Integrated Mobile Ad hoc Network (MANET)-Internet

This paper proposes a light weight solution for secure routing in integrated mobile ad hoc network (MANET)- Internet. The proposed framework addresses the following: i) application of IBC to ad hoc networks for efficient key management and for the distribution of pair-wise shared keys among the authenticated nodes; ii) providing secure Internet connectivity while the mobile node(MN) roams across different wireless domains operated by different agents and operators; and, Hi) design of a light weight secure ad hoc on-demand distance vector routing protocol for intra-MANET routing which protects all the fields of the routing packet including hop count. Security and performance analysis show that our proposed framework achieves good security while keeping the overhead and latency minimal.
