Embodiment Construction

[0041] Hereinafter, the present invention will be described more fully by referring to the accompanying drawings that show preferred embodiments of the invention. 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.

[0042] For ease of discussion, like numbers refer to like parts throughout. In addition, particular reference is made herein to Figures 1-10, wherein in alternate embodiments different reference numerals are used to designate like parts. For example, the mobile ad hoc network (MANET) nodes 11, 21, 31, 41, 51, 61, 71, 81, 91 and 101 depicted in Figures 1-10 are all identical components, and so on. Also, to avoid undue repetition, a component is only described in detail the first time it appears, however sub...

Abstract

A mobile ad-hoc network (MANET) (60) may include a plurality of nodes (61, 62) for transmitting data therebetween and a policing node (63). The policing node (63) may detect intrusions (64) into the MANET (60) by monitoring transmissions among the plurality of nodes (61, 62) to detect transmissions during an unauthorized period and generate an intrusion alert based thereon. The policing node (63) may also detect intrusions (64) 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.

Description

technical field [0001] The present invention relates to a mobile ad hoc network with intrusion detection features and related methods. Background technique [0002] Wireless networking has evolved over the past decade. One of the rapidly growing areas of wireless networking is the mobile ad hoc network, or "MANET" for short. Physically, a mobile ad hoc network consists of many mobile nodes that are geographically dispersed and share a common radio channel. Compared with other types of networks such as cellular networks or satellite networks, the most distinguishing feature of mobile ad hoc networks is that they do not have a fixed architecture. The network consists only of mobile nodes, and the network is established "on the fly" when the nodes are close enough to each other and perform a send or receive operation. This network does not depend on specific nodes and will be dynamically adjusted when some nodes join or other nodes leave the network. [0003] Because of the...
