Transmission control protocol (TCP) performance under multi-hop wireless network heavily depends on retransmission timeout (RTO) estimation algorithm. The existing Jacobson RTO estimation algorithm implemented in the TCP's retransmission (RT) timer collapses under multi-hop wireless environment due to sudden round trip time (RTT) delay spike, leads to the spurious timeout. This paper proposes an enhanced...
In this paper, a new queuing mechanism called proactive agile response (PAR) Queue proposed for the multi-hop wireless node that regulates the queue buildup and stabilizes the traffic flows under heavy traffic condition. The PAR uses multilevel packet marking with no additional computational complexity that notifies and controls congestion at its incipient stage. The PAR queuing algorithm supports...
Congestion occurs in the multi-hop wireless relay routers as the packet arrival rate outpaces traffic handling capacity. Congestion introduces packet loss, queuing delay and restraint formation of new connections in the networks. An intelligent queue management needed in the wireless relay routers that effectively regulate the queue accumulation and avoid network congestion. In this paper, an experimental...
Multi-hop technologies are recently gaining momentum due to its integration with wireless internet, Transmission Control Protocol (TCP), a consistent self clocking transport protocol plays a decisive role in an Internet's performance as it carries huge quantum of internet data traffic globally. TCP's performance over multi-hop wireless networks remains a challenging concern because of its characteristics,...
