Abstract
The recent trend in wireless communication networks has seen the focus shift from spectrum efficiency to energy efficiency. Use of multi clock-rate sampling devices to provide reduced power idle listening promises to significantly reduce power consumption in wireless devices without affecting throughput or transmission range. However, the use of frequency agnostic preamble to enable multi clock-rate detection causes linear scaling of preamble length, and consequently, the goodput performance of the network suffers. In this paper, we look at a modification of RObust Header Compression (ROHC) as a means to restrict header length scaling and its applicability in networks of multi-frequency sampling wireless devices. We analyze the modified preamble compression scheme deployed on multi clock-rate sampling wireless devices and determine performance metrics such as channel utilization and goodput across different error rates and downclocking factors. The energy efficiency performance of such a network is also studied. The results obtained are validated using extensive simulation.
