Most of the existing routing algorithms are based on two dimension, and the results can't be directly applied to the three dimensional wireless sensor networks, the Space Angle Based Energy-Aware routing algorithm in three dimensional wireless sensor networks is designed in this paper. Firstly, the Iterative Split Clustering algorithm for dividing the network nodes is proposed. Secondly, we design the Space Angel Energy routing algorithm to transfer data within the clusters and between the clusters respectively, achieving the goal of less energy consumption and extending the network lifetime. We simulate and implement the algorithm and evaluate the performance based on topologies with different scales, and get a conclusion that by comparing with the typical algorithm, the routing algorithms proposed in this paper are able to reduce the network energy consumption effectively and extend the network lifetime.

Aiming at the problem that routing nodes in Lora wireless network are no longer fixed like traditional wireless network, but can change dynamically with the increase and failure of nodes, a routing protocol based on Dijkstra algorithm is proposed. This routing protocol introduces the weight function with node energy into Dijkstra algorithm. The Matlab simulation results show that compared with the traditional Dijkstra algorithm, Floyd algorithm and ant colony algorithm, this algorithm has good performance in network life cycle and load balancing.

The IEEE 802.16 mesh network, which is self-organized and self-configured with multi-hop, is deployed to providing an effective solution for broadband wireless access system. The standard defines the basic scheduling scheme, but doesn't specify the resource allocation and routing scheme in the protocol. Therefore, designing a reasonable scheduling and routing algorithm to enhance the capability is very important for the system. In this paper, we propose an efficient and practical routing algorithm which takes the channel condition and modulation mode into consideration in an IEEE 802.16 mesh network. Furthermore, our algorithm enables direct communications between subscriber stations without referring to the base station. Simulation results show that our algorithm effectively improved the scheduling length, delay and system throughput.

To address the problems of large transmission delay and low success rate in DBGRS (Direction Based Geographic routing Scheme), we propose an novel routing algorithm which optimizes the process of data forwarding and makes full use of the information in the neighbor table to achieve the goal of reducing the transmission delay and increasing the success rate. Theoretical analysis and simulation results show that our proposed algorithm outperforms DBGRS in terms of average delay, number of packets transmission, and the success rate of packets transmission.

Vehicular Ad-hoc Network (VANET) is one of potential candidate to application of Intelligent Transport System in a city. This VANET technology allows any vehicle using this modem may be functioned as a repeater for other VANET members. In order to support emergency response to the public health facilities, use of VANET technology in the medical vehicles will improve punctual response in responding accidents or event natural disasters. This paper proposes a model and an application using clustering method for maintaining optimum and reliable communication among medical vehicles. This model applies in the urban environment (part of Surabaya City). Main tools are including the SUMO and the OMNet++ simulators are applied to simulate the scenario of the medical vehicle operation. The simulation combines the capability of SUMO in providing map of operation environment, delivery performance, routing algorithm of data transmission. Evaluation of the VANET communication performance is then applied to the packet delivery ratio (PDR), end-to-end delay and routing overhead. The simulation results show that the PDR, delay and the overhead is correlate linearly to the number of vehicles.

The relevancy of VANET has increased enormously in the last decade. This field of intelligent transport system has to deal with dynamic vehicular traffic with high mobility that makes multi-hop communication links more vulnerable and unreliable. To encounter the matters like delay, packet dropping, this research work proposes a novel routing algorithm named as Reduced routing Overhead using Ant Colony Optimization (RRO-ACO) with ACK packet broadcasting. Using Ant Colony Optimization (ACO) vehicular nodes can forward packet in more educated manner and use of ACK packets reduce redundant packet transmission. Traffic simulator SUMO and network simulator NS 2.34 are used to compare proposed algorithm with existing (Route Discovery-ACO) RDACO and RAGR (Road Aware Geographical routing). Results show that proposed method (RRO-ACO) outperforms the existing algorithms in terms of the Qos parameters like throughput, packet delivery ratio and network latency.

An efficient and low-cost communication system has great significance in the field of maritime communication, but it faces great challenges because of high communication cost, incomplete communication infrastructure, and inefficient data delivery algorithms. In this paper, we develop a long-term accurate trajectory prediction model by Bidirectional Long-Short Term Memory (Bi-LSTM) model. Based on predicted trajectories, we propose a data delivery algorithm based on predicted results to achieve efficient communication performance. Finally, we carry out simulation experiments with extensive real data. Compared with existing algorithms, the simulation results show that our algorithm can achieve higher delivery ratio with lower transmission delay.

In this work, we present an efficient fully adaptive fault-tolerant routing algorithm for 3D Network-on-Chip (3D NoC). The crucial algorithm for path routing is firstly routing the packet to the destination layer by using an adaptive vertical node assignment scheme in the NoC architecture with a limited quantity of TSVs and then routing to the destination node within the 2D layer through a fully adaptive routing algorithm. Instead of rerouting packets around the fault regions when fault occurs, our proposed algorithm applies a fault detection scheme which can get the fault information one hop away in advance, and it combines the fault information when doing the path computation. This algorithm can deal with multi faults in the 3D NoC architecture. Simulation results show that our proposed routing algorithm can achieve lower latency, energy consumption and higher packet arrival rate compared with other traditional routing algorithms in various network applications.

In order to solve the stability problem of communication network, network traffic instability is prevented, which is caused by local node or link failure. First, based on Lyapunov theory, a random queue model is established for communication network nodes to clear the traffic. Then, the factors are analyzed, which affects the network traffic stability. Finally, it proposes a dynamic scheduling multipath routing transmission algorithm to clear the network traffic steadily. Simulation and experimental results under the most unfavorable conditions of network stability, the performance of dynamic scheduling multipath route is verified to clear the traffic algorithm, which indicates that it is superior to traditional shortest path route dredging algorithm in ensuring network stability. It is proved that the dynamic scheduling multipath routing transmission algorithm can well suppress network turbulence by Lyapunov theory in the case of local network element failure, which ensures communication network stability.

This paper describes Optical Virtual Private Network (OVPN). The features and benefits of optical VPN are considered. Consider the OVPN model with a limited network resource on each section of the optical network. The optical network is described using the undirected graph with the set of nodes (correspond to the core optical nodes) and the set of edges (correspond to the link of the optical network connecting adjacent core nodes). Accepting the request for the implementation of OVPN, the service provider must, using the appropriate analysis algorithm, check whether the implementation of the corresponding virtual network is possible. To do this, the algorithm, firstly, selects a path between each pair of OVPN endpoints and, secondly, distributes the available bandwidth on each link in the selected path. If there is not enough bandwidth on the link, the received request for OVPN implementation will be rejected. Various algorithms for implementing the OVPN model: provider channels, individual flows and all flows OVPN are considered. This article discusses a possible approach to solving the problem of the distribution of optical network resources across several OVPN.
