Synergic prime number based asymmetric low duty period neighbor discovery method

Abstract

The invention discloses a synergic prime number based asymmetric low duty period neighbor discovery method. The method comprises the steps of selecting a corresponding duty period according to an energy requirement and a delay requirement of a mobile node; according to the duty period, selecting different parameters to arrange positions of an anchor time slot, a probe time slot and a prime number time slot and establishing a neighbor discovery scheduling table; and finishing neighbor discovery by the mobile node according to the neighbor discovery scheduling table. According to the method, a single synergic prime number is used, so that the quick asynchronous neighbor discovery can be finished within a bounded discovery delay, the number of optional duty periods is increased, and energy distribution is flexible. On the asymmetric low duty period condition, the low energy cost of the mobile node can be guaranteed, and the worst discovery delay can be shortened.

Description

technical field [0001] The invention relates to the technical field of mobile social networks, in particular to an asymmetric low-rotation cycle neighbor discovery method based on cooperative prime numbers. Background technique [0002] In recent years, mobile devices such as mobile sensors and smartphones have been widely and deeply used in various aspects. Most application-based mobile devices have the opportunity to meet each other. For example, two mobile devices meet by chance and communicate with each other; a certain mobile device needs to enter an established group and a plurality of mobile devices form a group. In these application scenarios, mobile devices are required to quickly discover neighboring users within their own communication range. [0003] In the emerging Internet of Things and mobile social networks, mobile devices face three challenges in completing neighbor discovery. 1. The energy of the mobile device is limited. In order to prolong the continu...

Problems solved by technology

2. The work of mobile devices is not synchronized, which will lead to greater discovery delays in networks with low duty cycles

3. Most applications running on mobile devices are very sensitive to latency, and require a smaller discovery latency during the neighbor discovery process

, the above three protocols show their superiority in coping with the challenges brought by energy efficiency and discovery delay, however, in the case of asymmetric low duty cycle, the performance is relatively poor
