摘要： In order to minimize the energy consumption in a duty-cycled asynchronous wireless communication network appropriate values of the operation parameters, i.e. the duration of the awake interval and the duration of the sleep interval, of the routing nodes (R1, R2, R3, R4, R5, R6, R7) of the network are determined and set. The energy consumption model takes into account the effect of random access; in order to simplify the model, the network is partitioned into a plurality of clusters (CL1, CL2,...) so that each of said clusters (CL1, CL2,...) comprises one cluster-head node (R3, R4,...). According to this model, the energy consumption of a cluster is a function primarily of the probability of busy channel when the nodes of the cluster attempt transmission, the probability of communication collision during transmission, the duration of the awake interval and the duration of the sleep interval of its cluster-head node. Minimization of the energy consumption is carried out under predetermined values of the probability of busy channel and of the probability of communication collision and under predetermined constraint for the probability of successful transfer of data packets within the cluster and for the average delay of transfer of data packets within the cluster; in this way, optimal values of the duration of the awake interval and the duration of the sleep interval of the cluster-head node are determined.

摘要： According to the present invention, a wireless network comprises permanently powered routing nodes (AOR) and intermittently operating routing nodes (SR); a polling procedure is used for transferring routing and data information packets from a permanently powered routing node (AOR) to an intermittently operating routing node (SR). In particular, when said permanently powered routing node (AOR) has to transmit an information packet to said intermittently operating routing node (SR) it stores said information packet into a memory, it waits until said intermittently operating routing node (SR) is able to receive information packets and then it transmits said information packet to said intermittently operating routing node (SR), and when said intermittently operating routing node (SR) has to transmit an information packet to said permanently powered routing node (AOR) it transmits immediately said information packet to said permanently powered routing node (AOR).

摘要： In wireless communication networks, especially in WPAN/WSN networks, there is a need to limit power consumption of network nodes; in asynchronous duty-cycled networks special MAC protocols are used for this purpose. According to the present invention, a source node (N1) estimates not only the schedule time offset of the destination node (N2) but also the clock drift of the destination node (N2); in this way, the source node (N1) may choose very accurately the transmission start time of an information packet to this destination node (N2) so that typically only one very short preamble needs to be transmitted. The estimation of time offset and clock drift between two nodes (N1, N2) is achieved through one or more previous transmissions between these two nodes (N1, N2); in particular, information relating to these parameters are transmitted from the destination node (N2) to the source node (N1) in reply to a preamble transmitted by the source node (N1) to the destination node (N2).
