Wireless sensor networks WSNs, are fastest growing ubiquitous networking used for monitoring and managing remote habitats. IEEE 802.15.4 standard was introduced for optimizing power consumption. For improving connectivity and enabling efficient data transfer with minimum modifications of the existing Internet stack, an adaptation layer, 6loWPAN, was introduced by IETF. This paper presents a novel header compression algorithm to combat with the reduction in the Maximum Transmission Unit of 6LoWPAN with respect to Internet. This improves the Quality of Service parameters such as throughput, delay and jitter variations. The size of fragmentation header is reduced by eliding the datagram_size field in in the in between fragments. the first and the last fragment and removing it This results in the reduction of fragment header size by 8 bytes, thereby yielding a reduction of 2.9ms in the transmission time for each IPv6 packet of nominal 1000 bytes payload. Contiki OS was used to record results to validate the effectiveness of the proposed algorithm.
