Roadside infrastructure can be used provide a wide variety of commercial services in vehicular ad hoc networks. One particular challenge is that of providing roadside radio coverage in highway locations where wired electricity is not available. In this case, roadside access points (APs) powered by renewable energy such as solar power, is a viable alternative. The cost of provisioning this type of...
Wireless LAN mesh networks are now being used to deploy Wi-Fi coverage in a wide variety of outdoor applications. In these types of networks, conventional WLAN mesh nodes must be operated using continuous electrical power connections. This requirement may often be very expensive, especially when the network includes expansive outdoor wireless coverage areas. An alternative is to operate some of the...
IEEE 802.11 access point (AP) power saving is an important feature for solar/battery powered ESS mesh networks. In this paper we propose a media access control (MAC) protocol for power-aware multihop infrastructure, based on extensions to IEEE 802.11(e). A power saving mesh AP includes a network allocation map (NAM) in its beacon broadcasts which specifies its temporal operation, and thus coordinates...
