Tutorial 2: Communication Protocols in Wireless Sensor Networks

"The tutorial addresses communication protocols networking issues in wireless sensor networks. After an introduction to into general features of sensor nodes such as platforms and energy consumption as well as a comparison of wireless sensor networks with mobile ad-hoc networks, we study lower layer communication protocols in wireless sensor networks. In particular, we present medium access control protocols and compare them with protocols used in wireless local area networks. Then, we discuss the issue of topology control and present routing protocols proposed for wireless sensor networks. Reliable transport protocols as required for management and reprogramming of sensor nodes will be compared. Finally, security mechanisms to ensure confidentiality, authentication and network availability will be presented."
