Wireless packet header compression techniques for Ship Area Sensor Network(SASN)

There is deep consideration of the proposed SASN(Ship Area Sensor Network) model in last year´s paper. For higher QoS of wireless sensor network part in the bulkhead of ship area, packet header compression techniques are considered as a method in this paper. Due to characteristic of SASN that wireless sensor nodes are almost fixed at specific position in initial installation because of that, sensor nodes transmit consecutive data with small difference compared to previous packet. Therefore it is useful to use packet header compression techniques to SASN. We introduce trend of packet header compression techniques and describe the characteristics of some well-known compression techniques which are Payload Header Suppression(PHS), Robust Header Compression(ROHC) and IPv6 over Low power Wireless Personal Area Network Header Compression(6LoWPAN HC). Also there is simulation showing throughput performance comparison of PHC, ROHC and 6LoWPAN HC in two different BER(Bit Error Rate) for consideration of suspicious circumstance. From the simulation result, we consider suitable packet header compression techniques for SASN.
