TCP Protocol base on multiplicative Decrease modification in Wireless Sensor Networks

Protocols efficiency is exactly in extensive spaces, since these spaces have less wind width, more delay and more emission time related to local spaces. Also lost package in these spaces are natural.But this ratio is very high in extensive space. In UDP Congestion space reach to 261% and this protocol don’t improve .Since these protocol set window size, decrease this size and increase this value .Weapply changes and α-β value are not fixed. One of major causes of this MTCP is all protocols repeated for package resend or awaiting for confirmation message, but they have not good efficiency in wirelessnetworks since they designed for wired networks .results approved MTCP is protocol can act in wired and wireless network. So they don’t need changes in application programs and medium nodes andTCP protocol should change .Also this protocol have good performance in random lost situation.
