Benefits of technology

This patent describes a system that uses multiple layers for sending data between devices. Each device has its own unique identifier called a MAC address or sequence number. When two devices want to communicate over this network they use these identifiers to determine if another device can join in communication without interfering with their original purpose. If any other devices are able to join it, they will generate an alarm when they see something like a certain number of them.

Problems solved by technology

This patent describes two technical problem addressed in the patent text: The first issue is how to identify and prevent intruder attacks in mobile ad hoc networks while also ensuring reliable communication between nodes in the network despite changing conditions like weather.

Embodiment Construction

[0039]The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0040]For purposes of the foregoing discussion, like numbers refer to like elements throughout. Moreover, referring particularly to FIGS. 1–10, reference numerals differing by decades are used to indicate similar elements in alternate embodiments. For example, the mobile ad-hoc network (MANET) nodes 11, 21, 31, 41, 51, 61, 71, 81, 91, and 101 illustrated in FIGS. 1–10 are all similar elements, and so on. As such, these elements may only be described in detail upon their first occurrence to avoid undue repe

Abstract

A mobile ad-hoc network (MANET) may include a plurality of nodes for transmitting data therebetween and a policing node. The policing node may detect intrusions into the MANET by monitoring transmissions among the plurality of nodes to detect transmissions during an unauthorized period and generate an intrusion alert based thereon. The policing node may also detect intrusions based upon one or more of integrity check values which do not correspond with respective data packets, usage of non-consecutive media access control (MAC) sequence numbers by a node, and collisions of packet types and/or MAC addresses.
