Evaluating TCP and Alternative Protocols for Enhanced Efficiency and Reliability in Wireless Sensor Network for Congestion Avoidance

---

Abstract

TCP is a protocol which is connection oriented that build a bridge between receiver and sender nodes before the initial packet transmission fire. If executed for WSN, where exact facts might be in order of small bytes, then a three-way complete activity will be become a difficult for a low volume of facts or data. Furthermore, in previous earlier attempt, a WSN is visualizing as framework of multi-hop where every intermediate hop connection is identified by its wasted and inaccurate vulnerable radio medium. As, TCP is protocol with end-to-end feature, schedule to structure TCP connectivity among two nodes end, that are notable number of hops separating each other which may be very large. Thus, for sensor nodes it is quite difficult for those nodes that are long way from sink to set sufficient round to help WSN applications that needed transmission of data continuously. In addition, the end-to-end technique become responsible for longer response in scenario of traffic or congestion and the result would give a larger number of portion drops. These portion drops mean there is unnecessarily power utilization or consumption. So, to ensure reliability, TCP follow end-to-end acknowledgment strategy, which low down the network throughput and increase the transmission time. In this paper, we have considered two protocols for the analysis of different parameters under different scenario, and this will help to measure the level of congestion and may help in increasing trustability for WSN. Delivery ratio of AODV is 83% and 78% of DSR is achieved with 25% load fraction of AODV and 23% for DSR.
