The present invention relates to a method for routing at least a data packet in a wireless sensor network (10), the wireless sensor network (10) comprising: at least a source node (S) that is configurable to transmit at least a data packet; at least a destination node (D) that is configurable to receive the data packet transmitted by the source node (S), and interconnectable network nodes (si) between the source node (S) and the destination node (D) that are configurable to receive and forward the data packet, the method comprising the steps of: operating the network nodes (si) according to a sleep-active schedule comprising at least a sleep mode and an active mode, and configuring the network nodes (si) to have information on their own geographic location and the geographic location of the destination node (D), the method further comprising the steps of: dividing the wireless sensor network (10) into a plurality of disjoint areas (A0, AM-1, A1, A2) that are separated by boundaries; separating each area (A0, AM-1, A1, A2) into at en least two regions, the regions being an inner boundary region (I), a central region (C) and an outer boundary region (O); selecting forwarding nodes out of the network nodes (si) to route the data packet from the source node (S) to the destination node (D), such forwarding nodes being selected on the basis of their geographic location relative to the destination node (D) and the network nodes being synchronized relative to each other, and configuring the sleep-active schedule such that only those forwarding nodes that are selected to route the data packet in a given time window are operable in the active mode and all the other network nodes (si) are operable in the sleep mode.

Method for routing data in a wireless sensor network

The invention discloses a wireless sensor network cluster routing protocol based on node depth. In a cluster head selection algorithm, residual energy of neighbor nodes are taken into consideration, so that the quantity of the cluster heads is stable, the cluster heads are distributed uniformly, and the problem that the nodes with low residual energy are selected as the cluster heads is avoided. Since the parameter of the node depth is introduced in a clustering process, the quantity of members of the cluster heads close to sink nodes is small, part of energy can be saved for transferring data of the other cluster heads, and the 'hot-spot' effect is relieved. Besides, affections of node depth values, residual energy and the quantity of the members of the cluster heads are taken into consideration fully during the process of selecting the next-hop nodes for the cluster heads, and accordingly energy consumption of the nodes is balanced further and network lifetime is prolonged.

Wireless sensor network cluster routing protocol based on node depth

The invention relates to a construction method of a time-delay-constrained energy consumption balance data acquisition tree in a WSN (Wireless Sensor Network). The construction method comprises the following steps: a data sink node calculates a weight of a node pair subjected to symmetrical network communication according to network topology information; the data sink node calculates shortest weighted paths from all nodes in the network to the data sink node, wherein a set of the shortest weighted paths forms a minimum weighted energy consumption generation tree; finding out the nodes in the minimum weighted energy consumption generation tree, which do not meet network time-delay limit, and calculating a corresponding topology adjusting scheme for each node as a candidate topology adjusting scheme; finding out one scheme with minimum adjustment on node transmission power from all the candidate topology adjusting schemes, and reconstructing the generation tree; and judging whether the nodes which do not meet hop count limit exist in the network, if so, continuously adjusting, and if not, ending the algorithm, wherein the generated generation tree is the final network topology result. According to the construction method disclosed by the invention, data effectiveness requirement is met, and energy consumptions of the nodes in the network are balanced.

Method for clustering hierarchical routing protocols of wireless sensor network

The invention discloses a rapid data aggregation-oriented wireless sensor and actor network clustering method, and belongs to the field of the wireless network. The method comprises the following steps of: judging the topological characteristic of a region of a sensor node by the sensor node; taking the number of transmission hops of the farthest answering sensor node as the farthest transmissiondistance; estimating the total number of sensors at each hop position in a cluster where the actor is positioned; determining a clustering scheme for a nearest region to be clustered; determining thecluster to which the region belongs; counting the actual clustering result of the region by the actor and substituting the result for an original estimated value; and obtaining the final clustering scheme until the clustering of all regions to be allocated in the network is finished. Through the method, the actual clustering condition is estimated by using the topological information of the network, the clustering scheme is designed and the calculation is simplified by using the estimated value, so that the aims of clustering the entire wireless actor and sensor network and distributing a communication task to each actor according to the geographic information in a balanced manner are fulfilled. Therefore,, the time delay for the information acquisition of the entire network is effectively reduced.

Rapid data aggregation-oriented wireless sensor and actor network clustering method

The invention provides a wireless sensor network hierarchical cluster-based routing method. The basic system composition comprises a common node, a relay node, a source node, a convergent node and a cluster head. The method is implemented by combining clustering thought with a multiple-hop mode, and providing a novel hierarchical cluster-based routing algorithm to improve the defects of LEACH protocol. The clustering mode can reduce network delay and is the optimized energy use efficiency mode, and the multiple-hop mode can fully exert the action of data amalgamation to reduce data amount. The nodes in the network are divided into a plurality of levels to be combined with the clustering method, and simultaneously an in-cluster cluster head alternation mechanism is adopted to enhance survival time of the network.
