%X Wireless Sensor Networks (WSNs) are resource constraint, and header compression can significantly reduce the amount of data transferred and improve channel utilization efficiency. The header characteristics and compressibility of the active message layer and communication layer in the protocol stack of the TinyOS were analyzed, then a header compression scheme for TinyOS was proposed, which could reduce the length of header significantly. First, communication components of TinyOS were modified and a new compression layer was inserted in the protocol stack to make the TinyOS support header compression. Then, based on a network composed of Micaz nodes, a header compression prototype system was designed and developed to implement the header compression scheme. The results of comparison experiments show that the prototype system can effectively reduce energy consumption and packet loss rate of the network.
