Accurate Energy Consumption Evaluation of Preamble Sampling MAC Protocols for WSN

Inhalt:
In this paper we present an accurate energy consumption evaluation of preamble sampling based MAC protocols for wireless sensor networks (WSN). The evaluation of software and hardware power consumptions is based on real-time measurements which explore the details of the current level drawn during all possible scenarios that can occur during the communication between sensor nodes. In typical asynchronous wireless sensor network applications, there are two types of collisions (control and data packets) that can occur during the communication between sensor nodes. Depending on the application and the network topology, these collisions can drastically increase the energy waste. The energy consumption is detailed for different application scenarios and some extensions of this accurate analysis are proposed to design energy-efficient networks.
