摘要:This paper addresses the problem of delivering data packets for highly dynamic mobile ad hoc networks in areliable and timely manner. Most existing ad hoc routing protocols are susceptible to node mobility, especially forlarge-scale networks. Driven by this issue, we propose an efficient Position-based Opportunistic Routing (POR)protocol which takes advantage of the stateless property of geographic routing and the broadcast nature of wirelessmedium. When a data packet is sent out, some of the neighbour nodes that have overheard the transmission will serveas forwarding candidates, and take turn to forward the packet if it is not relayed by the specific best forwarder within acertain period of time. By utilizing such in-the-air backup, communication is maintained without being interrupted.This intentional interference with wireless transmissions can be used as a launch pad for mounting Denial-of-Serviceattacks on wireless networks. Typically, jamming has been addressed under an external threat model. However,adversaries with internal knowledge of protocol specifications and network secrets can launch low-effort jammingattacks that are difficult to detect and counter. In this work, we address the problem of selective jamming attacks inwireless networks.
