The proposed research had two main purposes. The first was to develop simple, adaptive, and distributed energy control transmission power and transmission rate control algorithms that i control the topology of wireless ad hoc communication networks, subject to traffic with diverse bandwidth and end-to-end quality of service requirements, in a spectrally and energy efficient manner ii control multiple access interference and adapt to time-varying propagation losses and iii combine with transmission scheduling, media access control, and multi-hop routing. The second is to design simple, efficient, and robust mechanisms to improve the performance of Transmission Control Protocol TCP in mixed wiredwireless communication and ad-hoc networks. The basic approach is to study how the soon-to-be-standardized Selective Acknowledgement feature of TCP, together with knowledge of the statistical behavior of wireless links, can be used to decouple the error recovery and flow control functions of TCP by distinguishing between congestion and non-congestion related packet loss.
