Abstract :
ESS mesh networks will soon provide extensive coverage deployment for outdoor WLAN hotzones. In these types of networks, solar powered mesh access points (MAPs) and mesh points (MPs) can be used to provide tether-less infrastructure extension in an inexpensive and flexible manner. Unlike conventional WLAN networks, power saving on the access points (APs) is an important feature which can result in significantly reduced solar-powered AP node costs. Unfortunately, when infrastructure nodes conserve power, they become less responsive and this can significantly lengthen the hand off process. In this paper we propose and analyze different algorithms for mitigating these effects, so that real-time handoff can occur as fast as possible. Three different algorithms are proposed for dynamically activating the power saving infrastructure. The proposed algorithms are tested and compared to conventional handoff algorithms via simulation and analysis
