ABSTRACT
Wireless networks are characterized by the broadcast nature of the wireless channel, strong path loss, time varying fading and shadowing, and limited battery and processing power of the devices. These properties of the wireless physical layer interact in a complex manner with the higher layers of the protocol stack (MAC and routing), and present several interesting challenges when analyzing, dimensioning and designing wireless networks. The focus of this presentation is on discussing these cross-layer interactions, and the design of schemes which take advantage of these interactions.We will draw examples from different scenarios including wireless sensor networks, ad hoc networks and cellular networks.Joint work with Vivek Mhatre, Sunil Kulkarni, and Aravind Iyer.
