Abstract

Wireless sensor networks are often designed to operate on remote areas. Thus, sensor devices need to operate for years and have to save energy by switching their radio component off as often as possible. IEEE 802.15.4 is a standard that induces a low energy consumption. It divides time into an active period, where devices communicate, and an inactive period, where devices sleep. Many research has been done on how to optimize the medium access delay during the active period. Surprisingly, few studies take into account the inactive periods when analyzing the delay.
