The advance of wireless communication technology can make the communication between people without the limit of region and distance. One of the most important wireless technologies is Wireless Sensor Network (WSN). WSN is a distributed system that comprises thousands sensors and many sinks. The characteristics of a WSN include small-scale sensor nodes, limited power, mobility, dynamic network topology, wireless communication, etc. However, the sensors will collect the information and deliver it back to the sink node by using multi-hop wireless links from a specific region or nature environment. However, there are some problem in a WSN, suchlike communication jamming, message collision, and each SN has highly mobility in WSN, therefore, the network topology changes frequently and unstable. This study presents a stable protocol; the purposed protocol can improve the WSN to reach a more stable and reliable environment, and provides a high Quality of Service (QoS).
