Abstract

The invention discloses a routing method in a wireless sensor network, the wireless sensor network and node equipment based on the method. The routing method comprises the following steps: each node selects the nodes closer to the gateway than self from own neighbor nodes to form a candidate forward set; the node computes the payment equation value corresponding to each node in own candidate forward set; the neighbor node maximizing the payment equation value is selected as the next hop node; and after all the involved nodes select strategies, the route is established and data transmission is started. Based on the balance mechanism in the game theory, the invention can jointly optimize transmission reliability, network energy consumption and lifetime in the routing process and farthest save network energy consumption.

Description

technical field

[0001] The invention relates to the technical field of wireless self-organization and sensor network, in particular to a routing selection method in a wireless sensor network, and a wireless sensor network and node equipment based on the method. Background technique

[0002] With the development of sensor technology, embedded chip technology, distributed information processing technology and wireless network technology, Wireless Sensor Network (WSN) has emerged as a ubiquitous computing platform. WSN is composed of a large number of ubiquitous tiny sensor nodes with communication and computing capabilities densely arranged in unattended monitoring areas. It is an "intelligent" autonomous measurement and control network system that can independently complete specified tasks according to the environment. It is a network composed of tiny nodes integrating sensors, data processing units and wireless communication modules through self-organization and random distr...
