Interference with Overhearing for Secure Ad-Hoc Networks
Shimada Isamu, Hiroaki Higaki · DEStech Transactions on Computer Science and Engineering · 2017
In ad-hoc networks, data messages are transmitted from a source wireless node to a destination one along a wireless multihop transmission route consisting of a sequence of intermediate wireless nodes. Each intermediate wireless node forwards data messages to its nexthop wireless node. Here, a wireless signal carrying the data message is broadcasted by using an omni antenna and it is not difficult for a eavesdropper wireless node to overhear the wireless signal to get the data message.
