Mechanism for Packet Reordering in MANET
Quan Guo · 2009
The standard implementation of TCP experiences heavy throughput degradation when packets are reordered.This paper presented a new version of the TCP protocol,called TCP_D,which improves its performance to mobile-induced reordering packets in mobile ad hoc network(MANET).In TCP_D,the response to the receipt of duplicate acknowledgement is delayed by a short period to allow the receiver to receive the packets that travel in different path.We analyzed TCP_D to show that its steady state throughput is similar to the native implementations of TCP when packet reordering does not occur.The simulation results show that TCP_D performs consistently better than standard implementations of TCP under persistent packets reordering.In the case that packets are not reordered TCP_D maintains the same throughput as typical implementation of TCP(TCP-NewReno) and shares network resource fairly.
