An Extensive Evaluation of Transport Protocols Under Highly Congested Sensor Network

Free registration required

Executive Summary

In general, the performance of the congestion control algorithms of the presently available internet transport protocols for wired, wireless and mobile ad hoc networks, are highly reliable under the scenario for which they are meant for. However, their performance is not satisfactory under a high density sensor network application since, they are not designed for sensor network in mind. In this paper the performance of some of the standard transport protocols such as TCP, UDP, SCTP, DCCP-TCP-Like and DCCP-TFRC on a congested sensor network environment, based on certain suitable metrics, are evaluated using the package Network Simulator (NS2).
