Load Balanced Coding Aware Multipath Routing for Wireless Mesh networks

Chinese Journal of Electronics 2015年第1期24卷 8-12页

The growth of network coding opportunities is considered the unique optimization goal by most current network coding based routing algorithms for wireless mesh networks. This usually results in flows aggregation problem in areas with coding opportunities, and degrades the network performance. This paper proposes a Load balanced coding aware multipath routing(LCMR)for wireless mesh networks. To facilitate the evaluation of discovered multiple paths and the tradeoffs between coding opportunity and load balancing, a novel routing metric, Load balanced coding aware routing metric(LCRM) is presented, which considers the load degree of nodes when detects coding opportunities. LCMR could spread traffic over multipath to further balance load. Simulation results demonstrate that LCMR could evenly spread the traffic over the network with increasing network throughput in a heavy load at the expense of some coding opportunities.

This paper proposed a multi-domain virtual network embedding algorithm based on multi-controller SDN architecture. The local controller first selects candidate substrate nodes for each virtual node in the domain. Then the global controller abstracts substrate network topology based on the candidate nodes and boundary nodes of each domain, and applies Particle Swarm Optimization Algorithm on it to divide virtual network requests. Each local controller then embeds the virtual nodes of the divided single-domain virtual network requests in the domain, and cooperates with other local controllers to embed the inter-domain virtual links. Simulation experimental results show that the proposed algorithm has good performance in reducing embedding cost with good stability and scalability.

Mutual transfer learning aims to improve prediction with knowledge from related domains. Recently, federated learning is applied in this field to address the communication and privacy concerns. However, previous clustered federated learning (CFL) solutions lack theoretical guarantee of learnability recovery and require time-consuming hyper-parameter tuning, while centralized mutual transfer learning methods lack adaptability to concept drifts. In this paper, we propose the Adaptive Group Personalization method (AdaGrP) to overcome these challenges. We adaptively decide the recovery threshold with a nonparametric method, adaptive threshold correction, for tuning-free solution with relaxed condition. Theoretical results guarantee the perfect learnability recovery with the corrected threshold. Empirical results show AdaGrP achieves 16.9% average improvement in learnability structure recovery compared with state-of-the-art CFL baselines. Copyright 2024 by the author(s)

Game theory is applied to studying the P2P resource allocation technologies further in this paper. The mechanism of P2P resource pricing, which shows the relation of supply and demand, was presented based on bidding. Subsequently, we designed the utility function of end system and proved the existence and uniqueness of Nash Equilibrium in P2P resource allocation game. At last, we present a P2P resource allocation algorithm (PRANG) based on the resource allocation game model. The results of experiment and simulation show that PRANG algorithm can provide references for the quantity of resource that users demand and regularize the users' bids. Consequently, the allocation of the whole P2P resource tends to be more reasonable.

in high-voltage substations, poor contacts at the junctions of contacts can generate heat leading to high temperature, arc and fire disaster in serious condition. In this paper, we present a remote temperature monitor system to monitor and alarm when temperature of the contacts increases. The system measures temperature by sensor node based on low power consuming temperature sensor and Zigbee communication because power consuming becomes a critical fact constrained by long term running and inconvenient maintenance of high-voltage substations. In the system, sensor nodes are deployed on the contacts to be measured, cluster headers in charge of collecting data from sensor nodes are deployed on each distributor and cluster headers are connected with mast monitor computer via RS485 network. This paper presents design, implementation and test of sensor nodes, cluster headers and the master monitor software. © 2012 IEEE.

recently, intelligent home instruments developed fast and have been deployed widely while a crucial problem of how dealing the left devices and properties come up to the top of the water. This paper presents a remote gas meter reading system based on multimedia Zigbee networks and digital image recognition technologies to alleviate difficulties existing in traditional gas meter reading work while keeping existing gas meters unchanged. In the system, sensor nodes take picture of gas meter by a CMOS camera and send it to the sink node over multi-Zigbee-hop in a residential quarter. Then the gas providing company can access gas meter pictures through the Internet and recognize the data automatically by computer vision technology. Making up the gap between the high bandwidth consuming, high reliable requiring picture transport and the bandwidth constrained, error-prone Zigbee networks, this paper also proposes an opportunistic routing with network coding method to improve end-to-end throughput of the whole network. © 2012 IEEE.
