A Dynamic 6LoWPAN Context Table Maintaining algorithm

6LoWPAN protocol has been introduced to connect Wireless Sensor Network with the Internet. LoWPAN_IPHC is an up-to-date IPv6 packet header compression method. But there has been little consideration on the maintenance of IPHC CONTEXT TABLE. This paper analyzes this situation and presents a Dynamic 6LowPAN Context Table Maintaining algorithm to solve this problem. In our algorithm, we present the packets dealing process and introduce the age mechanism and the Context Table update mechanism. Experimental results verify the performance of our algorithm.
