Area Throughput for Multi-Sink Wireless Sensor Networks
In this chapter, the models for the evaluation of connectivity properties in multi-sink Wireless Sensor Networks (WSNs) and of the IEEE 802.15.4 Medium Access Control (MAC) protocol, described in Chaps. 4 and 5 respectively, have been integrated in a unique framework. The concept of area throughput, that is the amount of data per second successfully transmitted to the sinks from a given area, is introduced. This performance metric is strictly related to both connectivity and MAC issues: it depends, in fact, on the probability that a given sensor node is not isolated and that it succeeds in transmitting its packet (i.e., without collisions).
