A method and system for identifying harmful airborne biota, particularly insects, and including plant material, such as mold spores and pollen, and flying insects and birds and either killing ordisabling the harmful airborne biota is disclosed. Lasers, radar, and other types of radiation may be used to illuminate at least a perimeter around assets to be protected, with radiation returns detected and applied to a pattern classifier to determine whether the detected insects of interests are harmful, benign or beneficial. In the event the insects are determined to be harmful, a variety of measures responsive to the radiation returns may be taken to eliminate the harmful insects, these measures including firing pulses of beamed energy or radiation of a sufficient intensity to at least incapacitate them, or mechanical measures such as controlled drone aircraft to track and kill the pests.

A wire-less / Wired mesh network is described, using a multi-slot modular mesh node to house diverse transceiver elements (e.g. IR, Wi-Fi, Powerline). A radio agnostic tree based mesh network is formed, based on what type of wire-less links are formed on the uplink and downlink of the backhaul and what type of radios etc are used for the Access Points AP, see FIG. 17,23.In addition to servicing IP based clients (e.g. Wi-Fi, WiMax, Bluetooth), the modular mesh nodes APs may also serve as receivers / collectors for low cost chirp devices. These devices are not “agile” and therefore contentious. APs, servicing these devices, alleviate potential contention by multiple means including: sending out a “incoming” CTS, efficient delivery through container based schedulable bus deliveries, and its reverse (moving chirp transmission times to be sequential).Multiple approaches for “pollen” to reach the intended “flower” in a timely manner are described. The method of transport is standard IP based packets yet security is inherent in this pollen-flower based system: only mesh nodes are privy to the routing tables that indicate that packet addresses are not IP. Multiple options to further obfuscate packet flow are presented.A multi-agent based approach driving business process flow is described. Such agents can also provide specialized mesh network routing e.g. navigation agents for chirp devices.Tree based routing and logical radio abstractions are revisited.An organic approach to providing category / class based form of data type identification is proposed, to efficiently match publishers and subscribers, based on the type of data being sought. A private, secure and natively Publish / Subscribe M2M community is engendered at the edge. It has loosely, dynamic and ad hoc couplings to big data servers, also operating on their own private exchange / market place, using a real time publish / subscribe infrastructure with content categories used as part of pollen identification.
