ABSTRACT
In this paper we study the energy cost (protocol processing and communication cost) and goodput of two different flavors of TCP in ad hoc networks. We implemented a testbed and measured the actual energy cost as well as goodput of running TCP-SACK in ad hoc network scenarios. We also implemented Explicit Link Failure Notification (ELFN)[1] and Explicit Congestion Notification (ECN)[2] in Newreno and measured its performance. We see that the use of ECN & ELFN does yield higher goodput in most cases with a corresponding lower total energy cost. We see an energy savings of between 20% and 500% depending on the network conditions.

Energy consumption of TCP Reno, Newreno, and SACK in multi-hop wireless networks
SIGMETRICS '02: Proceedings of the 2002 ACM SIGMETRICS international conference on Measurement and modeling of computer systemsIn this paper we compare the energy consumption behavior of three versions of TCP --- Reno, Newreno, and SACK. The experiments were performed on a wireless testbed where we measured the energy consumed at the sender node. Our results indicate that, in ...
