PETAL: A fully distributed location service for wireless ad hoc networks [PDF]
Journal of Network and Computer Applications, 2017 Abstract Location service is an essential prerequisite for mobile wireless ad hoc networks (MANETs) in which the underlying routing protocol leverages physical location information of sender and receiver nodes. Fulfillment of this requirement is challenging partly due to the mobility and unpredictability of nodes in MANETs.

International Journal of Satellite Communications and Networking, EarlyView., 2023 The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

Distributed wireless network resource optimisation method based on mobile edge computing
IET Networks, EarlyView., 2022 This paper mainly compares the network ranking leader, consumption amount and network signal reception of the three algorithms. The study found that in terms of network sort captain, there are significant differences between the CPLEX algorithm, the CCST algorithm, and edge computing methods. The CCST algorithm and edge computing have little difference

Robust and low‐communication geographic routing for wireless ad hoc networks [PDF]
Wireless Communications and Mobile Computing, 2008 AbstractA novel beacon‐less algorithm called Blind Geographic Routing (BGR) is presented, which comes with an effective and robust recovery strategy to circumvent voids, and a new technique to avoid simultaneous forwarding by more than one node, features not included in other beacon‐less algorithms.

IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Low hitting time random walks in wireless networks [PDF]
Wireless Communications and Mobile Computing, 2008 AbstractRandom walks can be conveniently exploited for implementing probabilistic algorithms to solve many searching problems arised by distributed applications, for example, service discovery, p2p file sharing, etc. In this paper we consider random walks executed on uniform wireless networks and study how to reduce the expected number of walk steps ...

A formalized approach for designing a P2P‐based dynamic load balancing scheme [PDF]
Concurrency and Computation: Practice and Experience, 2009 AbstractQuality of service (QoS) is attracting more and more attention in many areas, including entertainment, emergency services, transaction services, and so on. Therefore, the study of QoS‐aware systems is becoming an important research topic in the area of distributed systems.

MAC protocols using directional antennas in IEEE 802.11 based ad hoc networks [PDF]
Wireless Communications and Mobile Computing, 2007 AbstractUsing directional antennas can be beneficial for wireless ad hoc networks consisting of a collection of wireless hosts. The most important benefit includes a reduction of the radio interference. Thus, it can significantly increase the spatial reuse, thereby improving the network throughput.

The capability of the EDCA mechanism to support voice traffic in a mixed voice/data transmission over 802.11e WLANs - an experimental investigation [PDF]
32nd IEEE Conference on Local Computer Networks (LCN 2007), 2007 —We analyze IEEE 802.16e medium access control (MAC) sublayer and provides a simple analytical model to compute the 802.16e MAC throughput. Our approach is to begin with a key approximation made by [1] in IEEE 802.11. This study leads to a fixed point equation, which characterizes the operating point of system.

N-Best Optimal Path Ant Routing Algorithm for State-Dependent N Best Quality of service Routes in IP Networks [PDF]
32nd IEEE Conference on Local Computer Networks (LCN 2007), 2007 For over a decade researchers have been reporting the impact of self-similar long-range dependent network traffic. Long-range dependence (LRD) is of great significance in traffic engineering problems such as measurement, queuing strategy, buffer sizing and admission and congestion control.
