Methods and Algorithms of Capacity Calculation and Increase Throughput in Wireless Sensor Networks base of ZigBee: A Survey

Background/Objectives: Wireless sensor networks with IEEE 802.15.4 standard are one of the most important computer networks in information technology today. Wireless sensor networks with powerful base stations and a large number of sensor nodes with limited resources are formed. The network throughput and capacity calculation is very important. Methods/Statistical Analysis: To provide low data rate to cover short and long battery life, ZigBee wireless sensor network node is used and the ZigBee wireless sensor network used as a ZigBee sensor node. ZigBee wireless sensor node system is generally based on the IEEE 802.15.4 standard and protocol, ZigBee protocol stacks that are made. The Methods compared with calculation, capacity and throughput parameters in wireless sensor networks in ZigBee based. Findings: We organize a summary of different challenges that are found in wireless sensor network while working on the performance enhancement of ZigBee protocol. Applications/Improvements: The paper categorized the different techniques of increasing throughput and calculating capacity of wireless sensor network using ZigBee based.
