Utilizing unmanned aerial vehicles (UAVs) as mobile access points can assist urban communication systems in establishing emergency networks in disaster scenarios. However, in large-scale dynamic environments, the extensive exploration space makes ...

LoRa is a low-power long-range Internet of Things (IoT) standard that offers remarkable performance, especially in remote rural areas. However the single-hop nature of current LoRa networks, poses significant challenges for urban setups and complex ...

It has been shown that it is impossible to achieve both stringent end-to-end deadline and reliability guarantees in a large network without having complete information of all future packet arrivals. In order to maintain desirable performance in the ...

The satellite network has the advantages of wide coverage, convenient access, and the influence of the natural environment. Wireless multi-hop network is suitable for the occasion that cannot be easily or inconvenient to lay network facilities and the ...

Recently, researches on resource allocation algorithms operating

in a distributed way are widely conducted because

of the increasing number of network nodes and the rapidly

changing the network environment. In this paper, we propose

new biologically ...

We present a communication protocol called Choco, which efficiently supports various traffic demands with end-to-end reliability in multi-hop Wireless Sensor Networks (WSNs). To achieve this, Choco uses fine-grained scheduling based on the insight that ...

A fundamental issue of underwater acoustic (UWA) communications is large propagation delays due to water medium. A new direction to address this issue is to take advantage of large propagation delays rather than enduring them as a disadvantage. Recent ...

As networks for providing wireless access easily and inexpensively with high robustness against network node failures, wireless mesh networks have been expected in recent years. However, wireless mesh networks consume numerous control packets to ...

This paper presents a new approach for the channel capacity calculation of a multi-relay multi-hop communication system. For the channel model based on Markov chains theory, the exact formula for the channel capacity, which is expressed as a function of ...

In most application scenarios of wireless sensor networks (WSN), sensor nodes are usually deployed randomly and do not have any knowledge about the network environment or even their ID's at the initial stage of their operations. In this paper, we ...

In this paper, we study the performance of IEEE 802.11a/b in a large-scale mobile railway networks and introduce our developed passive measurement approach. To provide a comprehensive evaluation, we built an outdoor multi-hop multi-interface railroad ...

Abnormal traffic detection is important to network management. This paper aims at the characteristic of multi-hop network, and defines abnormity that traffic-burst after failure. Then the paper presents a fast auto-adaptive traffic-aware abnormal ...

IEEE 802.15.4 is a protocol for low-rate wireless personal area networks. It contains two topologies: the star topology and the peer-to-peer topology. It has good performances for the star topology. However, the beacon collisions with other beacons, ...

A framework for advanced data processing in a multi-hop network is proposed and implemented in this paper. In the case of a distributed mobile DB, SQL queries are issued to multiple relational tables held by mobile nodes in MANET. Instead of collecting ...

This paper proposes a MAC protocol for efficient broadcasting in wireless ad hoc networks. Pure flooding leads to serious redundant broadcasts, packet contention and packet collisions, known as the broadcast storm problem . This paper focuses on how to ...

Sparse connectivity, limited energy, and restricted memory of Mobile Hosts (MHs) are the main characteristics of today's Mobile Ad hoc NETwork (MANET). Present wireless technology is now enabling MHs not only to have multi-hop communication among ...

A wireless multi-hop virtual cellular network (VCN) was recently proposed to avoid the large peak transmit power, resulting from the high transmission rates expected for future mobile communication systems. In VCN, calls hop through several links to ...

A self-organizing wireless network has to deal with reliability and congestion problems when the network size increases. In order to alleviate such problems, we designed and analyzed protocols and algorithms for a reliable and efficient multiple-layer ...

We propose a rate-controlled service discipline for supporting B-ISDN services. According to our approach, traffic streams from different connections can be well regulated at the output of each node based on their rate requirements. Moreover, the ...
