Relaying is a major technique to increase network lifetime in Wireless Sensor Networks (WSNs) and Body Area Networks (BANs). The results of relaying studies highly depend on power consumption model of relay's transmitter and receiver radio, channel and mobility models. In this paper, the authors study the effect of relaying with 2.4GHz IEEE802.15.4 modules on network lifetime. They analytically derive the energy expenditure of relays in which they use the path loss Probability Distribution Function (PDF) over links, which is derived from their link characterization using micaZ motes, and the existing power consumption models.
