Abstract: At present,the placement of edge servers has become a key step in the development of edge computing.Existing edge server placement methods are optimized by combining placement cost,network latency and system energy consumption,but most work ignores load balancing among edge servers.The goal of this paper is to minimize the service delay and load balancing of edge servers,and an optimization model of edge computing server placement is established.According to the optimization model,the optimal placement location is selected,and an edge server placement scheme based on an improved meta-heuristic algorithm,MIWOA-ESP,is proposed.It completes the multi-objective optimization and determines the distribution relationship between the base station and the edge server,and gives the optimal placement and distribution scheme.Finally,experiments are carried out using the Shanghai Telecom base station dataset.The results show that compared with other benchmark schemes,the MIWOA-ESP placement strategy has better performance in terms of network latency and server load balancing.

Key words: Edge computing, Server placement, Latency awareness, Load balancing
