Energy Consumption of TCP in Ad Hoc Networks

K.Bhavana, M.Himaja

Volume 14 Issue 8

Global Journal of Computer Science and Technology

In this paper we study the energy cost (protocol processing and communication cost) and goodput of different flavors of TCP (Transmission Control Protocol) in ad hoc networks.We implemented a tes tbed and measured the actual energy cost as well as goodput of running TCP Reno, Newreno, SACK (Selective ACKnowledgement) and a version that combines Explicit Link Failure Noti_cation (ELFN)and Explicit Congestion Noti_cation (ECN) in Newreno. We see that the use of ECN & ELFN does yield higher good put 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.
