The present invention relates to a method for operating a communication apparatus in a network comprising a plurality of communication nodes, upon reception of a message at the communication apparatus, the communication apparatus starting a retransmission delay being selected at random from a retransmission delay interval, said retransmission delay interval being dependent on at least one of a status of the communication apparatus and a property of the received message, the communication apparatus monitors retransmissions of said message by other communication nodes during said retransmission delay and the communication apparatus transmitting a retransmission of said message at the expiry of said retransmission delay if a statistic based on the retransmissions of said message by other communication nodes is below a threshold.

Method for operating a communication apparatus and communication apparatus

The present invention is a method of managing a neighbor table in a communication apparatus. The method includes the steps of the communication apparatus maintaining a neighbor table comprising a plurality of neighboring table entries corresponding to respective neighboring nodes being communication nodes in communication range of the communication apparatus. Upon determination that the neighbor table capacity has reached a threshold, replacing a first neighbor table entry corresponding to a first neighboring node from the neighbor table by a new neighbor table entry corresponding to a new neighboring node based on the determination that the new neighboring node is a communication partner. A communication node is defined as a communication partner if at least one the following conditions is met: a message including the communication partner as source address has been received by the communication apparatus, or a message including the communication partner as destination address has been transmitted by the communication apparatus.
