      11.1 Introduction One of the most important functions provided by wireless sensor networks (WSNs) is directly gathering data from the physical world. Generally, data gathering can be categorized as data collection [1][171][10], which gathers all the data from a network without any data aggregation or merging, and data aggregation [17]- [18], which obtains some aggregation values, e.g., MAX, MIN, SUM, etc. To evaluate network performance, network capacity, which reflects the data transmission/collection/broadcast rate, is usually used, e.g., multicast capacity [173], unicast capacity [175][176], broadcast capacity [177], and data collection capacity [1][171][10]. For data collection capacity, it is defined as the average data receiving rate at the sink, i.e., data collection capacity reflects how fast data been collected by the sink. We use data collection capacity and network capacity interchangeably throughout this chapter.
