Abstract: The present invention relates to the supervision of transactions in peer-to-peer (P2P) overlay networks. A P2P overlay network often consists of peers interconnected via different access technologies having significantly different round-trip time (RTT) delays. Current time supervisions of retransmissions and transactions in P2P networks have fixed values. This has the disadvantages that if the timer values are too short, unnecessary retransmissions are performed although a response would be on its way. If the timer values are too long it results in unnecessarily long messaging delays. These disadvantages have been overcome by a method and a peer for adapting the timer values to the conditions in the P2P overlay network.

Abstract: All wireless devices must comply with the local radio regulations which are set by international and national regulatory bodies such as the European Telecommunication Standardization Institute (ETSI) for Europe and the Federal Commission for Communication (FCC) for US. A new firmware module is proposed, that will ensure that devices, in all circumstances will comply with the ETSI regulations for single channel emissions in the 868 MHz ISM band. Namely, assuring compliance with the duty-cycle limit, the maximum TX time and minimum TX-off time limit. Such a solution has not been researched mostly due to the popularity of the virtually worldwide 2.4 GHz ISM band which does not have duty-cycle limitations. The wireless sensor networks (WSN) operating in the 868 MHz band have their own niche applications that benefit from the increased signal range. The development and the acceptance of such applications will benefit from the existence of the proposed module implemented in firmware/software.

Abstract: A control network communication arrangement includes a second protocol embedded into a first protocol in a way that modules supporting the second protocol may be aware of and utilize the first protocol whereas modules supporting only the first protocol may not be aware of the second protocol. Operation of modules using the second protocol does not disturb operation of the modules not configured to use or understand the second protocol. By one approach, the messages sent using the second protocol will be seen as messages sent using the first protocol but not having a message necessary to understand or as needing a particular response. In another approach, modules using the second protocol can be configured to send messages within a CAN message frame without being compatible with CAN.
