Leveraging a power save protocol to improve performance in ad hoc networks
Laura Marie Feeney, Christian Rohner, Bengt Ahlgren · ACM SIGMOBILE Mobile Computing and Communications Review · 2007
Power save protocols reduce energy consumption in ad hoc and sensor networks by allowing nodes to put their network interface into a low power consumption sleep state. The power save protocol must allow neighboring nodes to establish intervals during which they are mutually awake and available to exchange traffic. Many such protocols are based on a coordinated election of a covering set that is responsible for buffering traffic for sleeping nodes, but uncoordinated (i.e. asynchronous) protocols have also proven an attractive option.
