A Review on Wireless Mesh Networks

Wireless mesh networks (WMNs) are new kind of networking technology which facilitate the extension of wireless local area networks into wide areas and have emerged as a key technology for next-generation wireless networking.Due to the advantages of WMNs over other wireless networks,they are now a promising approach for future network access.Typical applications range from home broadband Internet access and community networking to wireless metropolitan area networks.Meanwhile,the considerable efforts in academic range from network architecture,network capacity,layered communication protocols,security,cross-layer design,etc.Still many technical challenges exist in designing affordable,reliable,and sustainable WMNs infrastructures.In order to provide a better understanding of these challenges,this paper presents a detailed investigation of current technologies for WMNs,and it will help to guide and refocus future works in this area.
