Abstract: The present invention provides a method of managing a context table for compressing a header based on a context to efficiently manage the context table and to increase a rate of a compressed packet in a low-power and Lossy networks (LLN) by applying a score to the context by taking a distance of a destination node and multi-casting transmission into consideration upon mutual communication between an external network and the LLN in a 6LoWPAN and registering the context in the table according to the highest order of the score. To this end, the present invention provides a method including the steps of determining a size of a score by taking into consideration traffic information of a packet transmitted from an external host by a boundary router connecting the LLN to an external network; assigning a context ID to a prefix of the transmitted packet by the boundary router based on the determined size of the score to register the context in the context table; and transmitting a packet of the context registered in the context table to all nodes of the LLN.
