Most studies on TCP over multi-hop wireless ad hoc networks have only addressed the issue of performance degradation due to temporarily broken routes, which results in TCP inability to distinguish between losses due to link failures or congestion. This problem tends to become more serious as network mobility increases. We tackle the equally important capture problem to which there has been little or no solution, and is present mostly in static and low mobility multihop wireless networks. This… CONTINUE READING

Key Quantitative Results

  • Through extensive simulation, COPAS is shown to improve TCP throughput by up to 90% while keeping routing overhead low.
  • Through extensive simulations, we have demonstrated that COPAS provides up to 90% improvement in TCP throughput than baseline DSR.
