Sensor Networks
Savo Glisic · 2016
Sensor network applications require wireless ad hoc networking techniques. A sensor network design is influenced by many parameters, which include fault tolerance, scalability, production costs, operating environment, sensor network topology, hardware constraints, transmission media, and power consumption. Data fusion or aggregation is an important concept in sensor networks. The key idea is to combine data from different sensors to eliminate redundant transmissions, and still provide a rich, multi-dimensional view of the environment being monitored. An important problem in sensor networking applications is boundary estimation. The objective is to consider measurements from a collection of sensors and determine the boundary between two fields of relatively homogeneous measurements. This chapter discusses the problem of finding an optimal transmission radius for flooding in sensor networks. It also provides an example of Equivalent Transport Control Protocol (ETCP) is the Event to Sink Reliable Transport (ESRT) protocol for wireless sensor networks (WSN).
