Problems solved by technology

However, the above-mentioned research results mainly focus on the selection and allocation of network channels, and only consider the limited measurement of routing, without comprehensively considering the network spectrum sensing conditions, the activity model of authorized users, the heterogeneous characteristics of channels, and the influence of radio frequency environment. It also does not consider the application of cooperative spectrum sensing technology in routing strategy

Embodiment Construction

[0028] A method for implementing an opportunistic routing protocol in a cognitive wireless network based on spectrum sensing, comprising the following steps:

[0029] Step 1. Each cognitive node adopts the spread spectrum sensing algorithm and realizes the fusion of detection information with each cognitive neighbor node through iteration to obtain the final detection judgment and determine whether the authorized user exists. If it is judged that the perceived channel is in an idle state, then Record this channel information in its own free channel set, including channel bandwidth, channel signal-to-noise ratio and channel availability probability, and then perceive the next channel until the state information of all channels is obtained;

[0030] Step 2. Route discovery process: Each cognitive node finds a possible suitable path and saves the suitable next-hop routing information, which forms the initial competitive node set;

[0031] Step 3: The cognitive node optimizes the ...

Abstract

The invention discloses a realization method for a cognitive radio network opportunistic routing protocol based on spectrum sensing. Idle available channels are rapidly discovered through adoption of a spread spectrum sensing algorithm; an initial competition node set is discovered through routing and priority sorting is carried out on the initial competition node set; the optimum relay node is selected for transmission of a data packet; and when the competition node set is optimized, delivery rates of nodes, residual energy and the distance between two nodes are taken into consideration, so an efficient, stable and reliable routing strategy is established, and a spectrum utilization rate is improved. The method has the beneficial effect that compared with an existing cognitive radio network routing protocol, the method has clear advantages over the average time delay, average energy consumption and average throughput.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for realizing a spectrum sensing-based cognitive wireless network opportunistic routing protocol. Background technique [0002] In recent decades, wireless communication technology has been greatly developed, from broadcasting, radio, television to mobile phones, and now wireless communication applications can be seen everywhere, making people's demand for wireless spectrum resources increasing day by day. Moreover, wireless spectrum resources are non-renewable resources like land, mineral deposits, grasslands, water and other physical resources. Therefore, how to improve the utilization rate of spectrum under the condition of effective wireless spectrum resources, so as to alleviate the current gradually intensified demand for radio services and scarce spectrum The contradiction between the two resources is the core technology of today's radio research. A brand-...
