摘要： Wireless Mesh Network (WMN) is a new- type wireless network. Its core idea is that any of its wireless equipment can act as both an Access Point (AP ) and a router. Each node in the network can s end and receive signals as well as directly communicate with one or several peer nodes . One important issue to be considered in wireless Mesh networks is how to secure reliable data transmission in multi- hop links . To solve the problem, the 3GPP system architecture proposes two functionalities : ARQ and HARQ . This paper presents two HARQ s chemes , namely hop - by- hop and edge - to - edge , and three ARQ schemes : hop - by- hop , edge - to - edge , and last- hop . Moreover, it proposes three solutions for WMNs from the perspective of protocol stock design : layered cooperative mechanism, relay ARQ mechanism and multi- hop mechanism.
