New adaptation method based on cross layer and TCP over protocols to improve QoS in mobile ad hoc network

Due to rapid growth of multimedia traffic used over the mobile ad-hoc networks (MANETs), keep up with progress this constraints MANETs protocols becoming increasingly concerned quality service. In view random mobility nodes in MANET, TCP becomes more unreliability case higher energy consumption and packet loss. paper we proposed a new optimization approach enhance decision making based on some changes IEEE 802.11 MAC uses cross layer approach. The aim is minimize impact retransmissions lost order analysed chose appropriate routing protocol for that can be QoS MANET. Our simulation results study using NS3 show that, our achieves better performance significantly, also improved throughput, facilitates transmission protocol.
