Self-organizing sensor networks hold the potential to revolutionize many segments of public security, environmental monitoring, and manufacturing. Sensors can be connected to form a network to enhance sensing capability. Like a computer network, a sensor network has a packet with a header flowing in a network of nodes (sensor nodes). This chapter presents the architectures and protocols of such networks, discussing the following topics:
• Sensor networks and protocol structures
• Communication energy model
• Clustering protocols
• Routing protocols
• Case study: simulation of a sensor network
• Other related technologies
We begin with an overview of sensor networks and explain some popular applications. We ...
