What does wireless sensor network study and what is the relationship with ZigBee? About wireless sensor networks, there are researches on routing calculation and topology control.

Wireless sensor network refers to the network based on wireless transmission, so there are many ways to realize wireless transmission, including zigbee and WiFi. Among them, zigbee is the most widely used in wireless sensor networks, and its biggest characteristics are low power consumption, long transmission distance and high security (128-bit encryption).

CC2530 is just a chip that can realize zigbee transmission. It's a chip of TI (Texas Instruments). Other chip companies also have zigbee-based chips, such as Freescale.

At present, zigbee-based wireless sensors are widely used in networks, such as cc 2530/cc 2430 chip of TI company. The chip is just a carrier to study wireless sensors.
