The most-frequently used radio in wireless mesh networks, i.e., 802.11, has short transmission range. Consequently, it mostly imposes multi-hop transmission and thus limits the utilization of radio bandwidth. Emerging radio technologies under the umbrella of 4G, having long transmission range, are capable of enhancing the bandwidth utilization through single-hop transmission at the expense of limiting spatial reuse over the network. Both of these excellences, i.e., the efficient bandwidth utilization and the spatial reuse, are required in case of a concurrent presence of two types of flows-base station oriented and random flows. Therefore, it is necessary to efficiently use both types of radios, i.e., 802.11 and 4G, in next-generation wireless mesh networks, as they are going to experience a mix of the two types of flows. We propose an architecture to guarantee the efficient usage of both the radios through their symbiotic coexistence. Extensive evaluation through analytical modeling, ns-2 simulation, and real testbed experiments reveals that our proposed architecture achieves up to approximately 6Â network throughput, 95 % decreased end-to-end delay, and 98 % decreased number of base stations compared to other radio alternatives.

“…Since, we did not make any changes of TCP, it reacts to losses the same way as the other flows and hence bandwidth aggregation does not interfere with other flows. On the contrary, approaches based on opening multiple TCP sockets as in [19,30] may be too aggressive in face of losses.…”

“…The Reliable Multiplexing Transport Protocol (RMTP) [24] is a rate-based transport protocol that multiplexes application data onto different channels. Parallel TCP (pTCP) [19] is another transport layer approach that opens multiple TCP connections one for each interface in use. Another reliable transport protocol proposed for use in message-based signaling in IP networks is the Stream Control Transmission Protocol (SCTP) [33].…”

“…Though many link layer solutions [3,16,31] exist, they are infeasible in our setup, as networks span different domains. While application and transport layer solutions as proposed in [19,24,26,30] can be used, they are cumbersome to implement as they involve many changes in the infrastructure-applications and/or server software have to be changed. Network layer solutions, on the other hand have the advantage of being totally transparent to applications and involve only minimal changes.…”

A Network Layer Approach to Enable TCP over Multiple Interfaces

The mobile Internet is set to become ubiquitous with the deployment of various wireless technologies. When heterogeneous wireless networks overlap in coverage, a mobile terminal can potentially use multiple wireless interfaces simultaneously. In this paper, we motivate the advantages of simultaneous use of multiple interfaces and present a network layer architecture that supports diverse multiaccess services. Our main focus is on one such service provided by the architecture: Bandwidth Aggregation (BAG), specifically for TCP applications.While aggregating bandwidth across multiple interfaces can improve raw throughput, it introduces challenges in the form of packet reordering for TCP applications. When packets are reordered, TCP misinterprets the duplicate ACKS received as indicative of packet loss and invokes congestion control. This can significantly lower TCP throughput and counter any gains that can be had through bandwidth aggregation. To improve overall performance of TCP, we take a two-pronged approach: (1) We propose a scheduling algorithm that partitions traffic onto the different paths (corresponding to each interface) such that reordering is minimized. The algorithm estimates available bandwidth and thereby minimizes reordering by sending packet pairs on the path that introduces the least amount of delay. (2) A buffer management policy is introduced at the client to hide any residual reordering from TCP. We show through simulations that our network-layer approach can achieve good bandwidth aggregation under a variety of network conditions.

Device‐centric communications will constitute a key technology in the fifth‐generation (5G) networks, where mobile devices in near proximity participate in direct communications among each other bypassing the cellular base station. Such communication schemes are known as device‐to‐device (D2D) communications, which are anticipated to improve energy efficiency, decrease latency, improve spectrum utilization, and many other benefits. With the technological advancement in smartphones, multiple radio interfaces can be supported within the same mobile device. When these multi‐radio access technologies (RATs) are efficiently exploited, they give rise to a new emerging feature in device‐centric systems, such as devices‐to‐device (Ds2D) and devices‐to‐devices (Ds2Ds) communication modes. In this chapter, we highlight the different multi‐RAT D2D architectures, where we discuss the different criteria for switching between multi‐RAT D2D and cellular operation modes. The radio channel model and the different spectrum access techniques are also discussed. Then, the major benefits of multi‐RAT D2D such as energy efficiency and low latency are highlighted. Challenging issues that arise at different layers of the network protocol stack are discussed, with an emphasis on the medium access control, network, and transport layers. Finally, open research issues that require further investigations to get the most out of multi‐RAT D2D communications are discussed.
