An Optimization Framework for IEEE 802.11s Based Wireless Mesh Network

Wireless mesh network (WMN) is a promising area of research. Energy efficiency in WMN can play vital role in achieving green wireless communication. This research work considers IEEE 802.11s link based power saving modes. Energy aware joint optimization of routing, link scheduling under wireless interference and delay constraint has been considered. For given traffic load a model has been formulated to minimize network energy consumption by choosing optimum power saving mode for peer links. It is stressed that redundant links and nodes can be turned in low power state for energy savings
