With the development of 5G network and big data and the popularity of mobile intelligent devices, the opportunistic social network has been further developed. At present, several existing routing algorithms based on node similarity use the context information of the node to select the best relay node. However, most opportunistic social algorithms only consider the social properties of nodes and ignore the importance of the similarity of the moving trajectories of the nodes. The transmission opportunity of messages in the opportunity social network is generated by the movement of the nodes, so this feature must betaken into account in the designing of the routing algorithm. Therefore, this study proposes a routing algorithm based on the triangular fuzzy layer model and multi-layer clustering for the opportunistic social network. In this study, the authors use the fuzzy analytic hierarchy process model to analyse the social similarity and trajectory similarity to determine the best message transmission node. This study compares the other four opportunistic social network routing algorithms in the simulation environment. In general, among the five routing algorithms, the transmission rate of the TFMC algorithm is the best. The average end-to-end delay and average network overhead are also the lowest.

Most of the existing routing protocols from those in the terrestrial networks can not be directly applied in Deep Space Information Networks (DSINs), because of its inherent outstanding characteristics, such as bandwidth constraints, high latency, asymmetric data rates, and heterogeneous network architectures. Therefore, designing an optimal routing algorithm that is suitable for DSINs becomes a challenging and interesting problem. In this paper, a bandwidth allocation scheme based on non-cooperative differential game is proposed. Our scheme takes the selfness of nodes into consideration. It is shown that our proposed scheme can effectively allocate bandwidth with bandwidth constraints, and is more feasible and adaptive to DSINs with bandwidth constraints.

Divisor-Skip Wavelength Division Multiplexing (DS-WDM) ring is an optical interconnection network for workstation clusters or parallel machines which can connect various number of nodes easily using wavelength division multiplexing techniques. However, the wavelength-ordered routine algorithm proposed for the DS-WDM ring requires complicated processes in each router. Here, a new routing algorithm called the comparing dimensional number routing algorithm for the DS-WDM ring is proposed and evaluated. Although the diameter and average distance are almost same as traditional wavelength-ordered routing, the cost and latency are much reduced.

A search method based on Particle Swarm Optimisation to search simutaneously the energy function coefficients and the parameters of the Hopfield Neural Network (HNN) algorithm is proposed. Experiments using three differents communication networks are presented. The results show that the proposed approach achieves better results than existing algorithms that employ the HNN for routing. Some results show that the algorithm tends to be quicker than Dijkstra for larger communication networks.

routing algorithm that broadcasts bitmap with random waiting for wireless sensor networks

This paper describes a routing algorithm that broadcasts a bitmap with random waiting to reduce the number of messages transferred when establishing routing paths. Existing routing algorithms do not include routing tables for determining a path, as this would increase the cost, since sensor nodes are invariably mobile and have a limited capacity and restricted resources. However, this study proposes a sensor node that includes a routing table in the form of a bitmap, thereby reducing the size of the routing table. A bitmap is formed with a two-dimensional array, where each row and column are represented by one bit. Plus, when a node transfers routing information, it must wait randomly before transmitting to its neighbors, allowing redundant paths to open up when the bitmap is broadcast. After broadcasting, if a node then receives a bitmap from other adjacent nodes, it only updates its own bitmap. Thus, each node has a bitmap with partial link information on the network, rather than total link information. As a result, the proposed routing algorithm effectively reduces the number of messages involved in routing establishment when compared to existing algorithms.

An agent-assisted QoS-based routing algorithm for wireless sensor networks

Existing routing algorithms are not effective in supporting the dynamic characteristics of wireless sensor networks (WSNs) and cannot ensure sufficient quality of service in WSN applications. This paper proposes a novel agent-assisted QoS-based routing algorithm for wireless sensor networks. In the proposed algorithm, the synthetic QoS of WSNs is chosen as the adaptive value of a Particle Swarm Optimization algorithm to improve the overall performance of network. Intelligent software agents are used to monitor changes in network topology, network communication flow, and each node's routing state. These agents can then participate in network routing and network maintenance. Experiment results show that the proposed algorithm can ensure better quality of service in wireless sensor networks compared with traditional algorithms.

Simplified Energy-Balanced Alternative-Aware routing algorithm for Wireless Body Area Networks

Nowadays, the needs of healthcare for the elderly are growing rapidly. To provide continuous all-day medical monitoring and diagnoses at low cost, wireless body area networks (WBANs) have become a forward-looking technology since it is regarded as a potential solution for the remote collecting of physical and symptoms information. Because of its application characteristics, reliability and delay are the most important, as the energy consumption also needs to be considered. However, due to the limitation of the large propagation loss and the complicated channel conditions, the existing routing algorithms cannot completely address the above problems. To balance the node energy consumption and reduce the transmission delay, a simplified energy-balanced alternative-aware routing algorithm (SEAR) for WBANs is proposed in this paper. The residual energy and the current load of a candidate of the next hop destination are considered during the routing request forwarding procedures. The required information is exchanged during the improved routing request and routing request response procedures, and the routing cost is modified accordingly. To improve the compatibility and robustness, the added path is introduced as an alternative path in our algorithm. The simulation results show that SEAR achieves significantly higher network residual energy and network throughput, and end-to-end delay is also reduced. Therefore, the lifetime of the network is extended effectively.

Based on the study on communication situation of mobile ad hoc network (MANET) accessing Internet and taking the gateway important function of accessing network into account, a MANET accessing Internet routing algorithm based on dynamic gateway adaptive selection (MRBDAS) is presented. It considers candidate gateways’ connecting degree, load degree, residual energy, and movement rate synthetically and uses the idea of group decision-making method for reference. The algorithm employs the methods of multipaths and query localization technique based on old path information to maintain routing adaptively. Compared with the existing accessing routing algorithm based on dynamic gateway, the algorithm demonstrates in its simulations that by bringing dynamic gateways colony function, the MRBDAS can improve network throughput, reduce average transmission delay of data packets and routing overhead, and prolong accessing network life. The validity of MRBDAS has been proven. Keywords routing algorithm - gateway selection - dynamic gateway - mobile ad hoc network (MANET) accessing
