ICTP: An improved data collection protocol based OnCTP

Data collection is one of the basic tasks of WSN, and data collection protocol occupies a pivotal position in WSN. Data collection protocol in TinyOS 2.0 is implemented in the form of Collection Tree Protocol (CTP). However, CTP have proved to be extremely efficient, in practical applications, CTP also have some disadvantages. The paper presents an improved data collection protocol ICTP based on the analysis of CTP. The protocol introduces the concept of load balance into CTP. Finally, with the simulation results, we have proved that our improvement improves the efficiency and performance of the data collection task in WSN. There is something noteworthy that ICPT doesn´t have additional energy as a result of not selecting the optimal path.
