Aims

This course will cover topics in the area of mobile systems and communications as well as sensor systems and networking and the mixture of the two. It aims to help students develop and understand the additional complexity introduced by mobility and by energy constraints of modern systems.

Lectures

  • Wireless propagation and MAC Layer. Differences in transmission in wired and wireless medium. Introduction to MAC layer protocols of wireless and mobile systems.

  • Mobile phones architectures and communication. Introduction to existing mobile phones and operating systems for mobiles.

  • Mobile Infrastructure communication and opportunistic networking protocol. Description of common communication architectures and protocols for mobile phones and introduction to models of opportunistic networking.

  • Introduction to sensor systems architecture. sensor systems challenges and applications.

  • Sensor systems MAC layer protocols. Introduction to concepts related to duty cycling and energy preservation protocols.

  • Sensor systems routing protocols. Communication protocols, data aggregation and dissemination in sensor networks.

  • Sensor systems programming and reprogramming. Motivation of sensor reprogramming and approaches to sensor network management and update.

  • Mobile sensing and participatory sensing. Mobile sensor networks and use of mobile phones as sensors.

Objectives

On completing the course, students should be able to

  • describe similarities and differences between standard distributed systems and mobile and sensor systems;

  • explain the fundamental tradeoffs related to energy limitations and communication needs in these systems;

  • argue for and against different mobile and sensor systems architectures and protocols.
