The objective of this proposal is to select and develop header compression techniques suitable for ad-hoc networks, and demonstrate their viability by analysis and simulation.. Recent header compression technology has been shown to be able to reduce overall packet sizes substantially, e.g., from 76 bytes (IPv6/UDP/RTP/payload) down to around 17 bytes (1 byte/payload). This reduction of 78 per cent has been achieved for voice traffic over mobile phone links. If similar gains can be realized across ad-hoc networks, a significant increase in available bandwidth, a reduction of packet loss rates, and a reduction of delay variance would follow. This will make voice and video transmission more efficient across wireless ad-hoc networks. The developed techniques will be applicable to any tunnels across the Internet, including encrypted tunnels for businesses

We propose to implement and standardize header compression protocols for ad-hoc networks. In Phase I, we have demonstrated that header compression can increase the amount of available network bandwidth, reduce network delay, and reduce network delay variance in an ad-hoc network. This is beneficial for applications such as voice and video. Now we propose to realize the protocols designed in Phase I and Phase I Bridge. Phase II will complete with real-world demonstrations of the viability of a two-level header comression architecture using laptops and voice and video applications running over an AODV network.

Benefits:
This will make voice and video transmission more efficient across wireless ad-hoc networks. The developed techniques will be applicable to any tunnels across the Internet, including encrypted tunnels for businesses.
