A Concurrent Multi-path Transfer Mechanism Used in Ad Hoc Networks

Many works have examined the problem of receive buffer blocking which is brought by traditional concurrent multi-path transfer protocol. A new concurrent Multi-path transport mechanism named Wireless concurrent multi-path transfer SCTP protocol (WCMT-SCTP) is proposed in this paper. WCMT-SCTP is designed for solving the receive buffer blocking problem. It can bind the certain data streams to certain paths and use multiple active paths to transfer data simultaneously. An analysis is given to demonstrate the performance of WCMT-SCTP, and simulations are conducted to show the performance improvement of WCMT-SCTP in terms of throughput and the independence of data streams. It is also shown that analysis results are fitting well with the simulation results.
