Abstract
With the large scale deployment of multihomed mobile computing devices in today’s Internet, the Multipath TCP (MPTCP) is being considered as a preferred data transmission technology in the future Internet due to its promising features of bandwidth aggregation and multipath transmission. However, MPTCP is more likely to be vulnerable to the transmission quality differences of multiple paths, which cause a “hot-potato” out-of-order arrival of packets at the receiver side, and in the absence of a related approach to fix this issue, serious application level performance degradations will occur. In this paper, we proposes MPTCP-LM 3 , a Lightweight path Management Mechanism to aid Multihomed MPTCP based mobile computing devices towards efficient multipath data transmission. The goals of MPTCP-LM 3 are: (i) to offer MPTCP a promising path management mechanism, (ii) to reduce out-of-order data reception and protect against receiver buffer blocking, and (iii) to increase the throughput of mobile computing devices in a multihomed wireless environment. Simulations show that MPTCP-LM 3 outperforms the current MPTCP schemes in terms of performance and quality of service.
Highlights
In the past several years, wireless communications systems and networks have experienced a dramatic development [1]
We here compare the performance of our Multipath TCP (MPTCP)-LM3 with the baseline MPTCP [7] and our previous work (PU)2 M2 [14]
We can observe that between 30 and 50 s of simulation time, MPTCP-LM3 and MPTCP + (PU)2 M2 performed at a lower level of data sending and receiving times than the baseline MPTCP
Summary
In the past several years, wireless communications systems and networks have experienced a dramatic development [1] These dramatic advances in wireless communications and networking technologies provide ubiquitous Internet connectivity to a mobile user [2]. The Apple iOS based products (i.e., iPhone and iPad) [5] and Samsung Galaxy mobile phones (i.e., S9 and S9 Plus) [6] can use both the Wi-Fi and cellular network links to download large files. Such multihomed devices can speed up the transmission
