JWCN_V3_N1_RevP1 A Review on Optimal Node Placement Methods in Wireless Mesh Network Planning G. Merlin Sheeba Alamelu Nachiappan Journal On Wireless Communication Networks 2320 - 2351 3 1 35 40 Gateway Placement, Access Points, Optimization, Constraints Wireless Local Area Network (WLAN) technology has matured to provide more efficient and flexible solution, through the wireless network anywhere on campus for internet access with less investment. WLAN mesh networks consist of Mesh Routers, Mesh Access Points (MAP), Mesh Gateways/Mesh Point Portal. Planning a network by minimizing the number of devices with better connectivity and coverage for cost effectiveness is a challenging issue. The gateway nodes in WMNs operate as integration points between the multi-hop wireless network and the wired network. Appropriate placement of such integration points is a critical factor in achievable system capacity. April - June 2014 Copyright © 2014 i-manager publications.
