A wireless sensor network (WSN), sometimes referred as WSAN, wireless sensor and actuator network . WSANs are used to monitor environmental or physical parameters like pressure, temperature, sound etc. WSANs are independent sensors allotted spatially and monitors the aforesaid terms ,and transfers datacooperatively through the network to a main gateway. In Wireless Sensor Network, Time Slot to Transmit is an important point for Data in between Different branches of Tree (T). This paper presents a Compressive Improved Aggregation Scheduling algorithm (CIAS) and comparison between CIAS, IAS (Improved Aggregation Scheduling) and DAS (Distributed Aggregation Scheduling) algorithms . The main area of discussion is low TST (Time Slot to Transmit) which provides fast data communication .
