Embodiment Construction

[0025] This embodiment provides a QoS-driven mobile edge network resource allocation method, wherein, as figure 2 As shown, the mobile edge network system consists of N users, an auctioneer and an edge server. Assume that users in the mobile edge network are divided into P classes and for each user i there is only one computing task k i Needs to be offloaded to the edge server. At the beginning of each auction round, each user i submits a bid vector to the auctioneer where s i means k i The start time of τ i means k i The delay requirement, d i means k i The computing resources required, c i means k i required communication resources, and Respectively represent user i’s bid for unit computing resource and unit communication resource, λ i means k i the size of z i means k i strength, p i Indicates the level of the user. The execution time of the defined task is divided into three parts: upload, execution, and download. Since the amount of tasks in the downl...

Abstract

The invention discloses a QoS-driven mobile edge network resource allocation method, which comprises the following steps of: S1, judging whether a calculation task meets a constraint condition or notfor any user, if so, submitting a bidding vector to an auctioneer by the user, otherwise, giving up the calculation task by the user; s2, acquiring an emergency degree of the calculation task, and calculating a normalized emergency degree; s3, calculating a unit calculation resource bid and a unit communication resource bid of the user according to the emergency degree; s4, the auctioneer collecting bid vectors submitted by the users of all levels and calculates the number of resource blocks obtained by the users of all levels; s5, allocating resources to the users of each level and determining winners and payment fees of the winners; and S6, sequentially judging whether tasks with grades are rejected or not, and if so, extracting resources from other resource blocks with spare resources.According to the method, differentiated services are provided for users by utilizing an auction theory according to QoS requirements of the users of different levels, so that the income of operators is maximized.

Description

technical field [0001] The invention belongs to the field of mobile edge technology, and in particular relates to a QoS-driven mobile edge network resource allocation method. Background technique [0002] Explosive traffic growth in recent years has forced changes in the mobile network architecture. Traditional cloud computing centers can no longer meet the requirements of new applications such as virtual reality and real-time holographic projection. Computing sinking has become a trend. As a new computing mode, mobile edge computing can reduce transmission delay and network congestion because it is at the edge of the network on the one hand; Provide users with convenient cloud services. However, due to the large number of users and the different QoS of different users, how to allocate the resources of the edge server is particularly important. [0003] Auctions are widely used in theoretical economics as an effective means of allocating resources. In recent years, with t...
