Power Efficient and Secure IPV6 Robust Header Compression Technique for Low Power Wireless Personal Area NetworksPower Efficient and Secure IPV6 Robust Header Compression Technique for Low Power Wireless Personal Area Networks

A power efficient & secure ROHC scheme has been presented in this paper. This scheme is designed to work efficiently for IPV6 based low power wireless personal area networks. The proposed scheme first implements ROHC followed by a suitable encryption scheme. ROHC can greatly reduce the size without adding too much complexity to the system. This in result improves the data rate without costing too much power. IPV6 lowpans have a number of applications in military and emergency scenarios. Therefore providing high data rate with security is the prime requirement especially for military applications. For our design we have tested three different encryption schemes. DES gives the best power efficiency as compared to TDES but it is less secure and information can be cracked. TDES is three times computationally more expensive but gives more secure option. Kasumi gives a middle solution. A computer simulation for the whole system has been tested to verify the data rate & power efficiency. The result clearly suggest that proposed system gives a higher data rate with better security and power efficiency.
