Wireless sensor network clustering collaborative routing algorithm based on cooperative game

Abstract

The invention provides an uneven clustering collaborative routing algorithm based on the cooperative game, and aims at the hotspot problem caused by uneven energy consumption in a wireless sensor network. According to the algorithm, factors of the positions, residual energy and communication cost of nodes are comprehensively considered in clustering, a campaign function is constructed according to the factors, the weight of each factor is weighed by utilizing the cooperative game to search the optimal node to act as a cluster head, and common nodes joins corresponding clusters according to the distance between the common nodes and the cluster head and the distance between the cluster head and aggregation nodes. Besides, a collaborative forwarding node is selected in each cluster according to information of the node residual energy and position in the routing phase further, and the collaborative forwarding node is utilized to forward data transmitted by the cluster head so as to avoid excessively fast energy consumption of the cluster head. The simulation result indicates that energy consumption of the network can be effectively equalized and the hotspot problem of the network can be alleviated by the algorithm so that the life cycle of the network can be prolonged.

Description

technical field [0001] The invention relates to a cooperative game-based wireless sensor network clustering cooperative routing algorithm, which belongs to the technical field of wireless communication. Background technique [0002] Wireless Sensor Network (Wireless Sensor Network, WSN) is a wireless network formed by a large number of static or mobile micro-sensor nodes through high-density deployment in a self-organizing and multi-hop manner, which has the characteristics of flexibility and low power consumption. After the nodes are deployed in the target monitoring area, they can perceive and detect multi-dimensional information of the target object, such as sound, object health status, temperature, intrusion objects and their movement status, etc., through mutual cooperation among nodes, and process and send the monitored data through Network transmissions provide information to decision makers. [0003] Since the energy carried by wireless sensor nodes is limited, and ...
