- Heuristic-based link quality preservation for reliable data delivery
Gokila K. and Vennila Ila.
Version of Record online: 24 FEB 2017 | DOI: 10.1002/dac.3304
This paper proposes the solution to maximum data forwarding time, connectivity disruption during the topological changes and the interference existence among the nodes. Based on the received signal strength indicator (RSSI), bandwidth, node mobility, and the number of connections, the weight assignment to the path is the major process in proposed work. With RSSI measure, the quality factor is estimated. The integration of taboo list with the heuristic approaches provides the support to the link preservation and the update of link failures to alternate the path among the nodes.
- Levenberg-Marquardt optimization method for coverage and connectivity control in backbone-based wireless networks
Khalid Khan and D. K. Lobiyal
Version of Record online: 22 FEB 2017 | DOI: 10.1002/dac.3296
In this paper, we propose the use of Levenberg-Marquardt optimization algorithm to achieve assured coverage and connectivity control in backbone-based wireless networks. Simulation is performed to demonstrate the effectiveness in terms of the number of iterations, elapsed time, and power requirement. The performance is compared with Cauchy steepest descent method as well as Newton-Raphson method.
- An energy-efficient algorithm based on sleep-scheduling in IP backbone networks
Fahimeh Dabaghi-Zarandi and Zeinab Movahedi
Version of Record online: 21 FEB 2017 | DOI: 10.1002/dac.3276
In this paper, we propose a new Distributed Green Algorithm based on Sleep-scheduling (DGAS) to save energy in Internet backbone networks. The DGAS switches off some low-occurrent network links and nodes in 2 consecutive decremental and incremental phases. Our solution does not depend on any centralized controller and any knowledge of traffic matrix.
- Performance comparison of dual-hop hybrid decode-or-amplify-forward relay schemes for M-ary quadrature amplitude modulation burst transmission over Rayleigh fading channels
Choongchae Woo, Sungmook Lim and Kyunbyoung Ko
Version of Record online: 20 FEB 2017 | DOI: 10.1002/dac.3295
This paper shows the analytical performance expressions of M-ary quadrature amplitude modulation (M-QAM) burst symbol transmission for hybrid decode-or-amplify-forward (HDAF) relay schemes over quasi-static Rayleigh fading channels. The analysis shows the superiority of HDAF scheme to ADF scheme, especially in higher order modulation and more numbers of relays. Comparison with simulations confirms that the derived analytical expressions are accurate over all SNR regions and for different numbers of relays and modulation orders.
- Cluster based resource allocation in two-tier HetNets with hierarchical throughput constraints
Li Li and Zhaorong Zhou
Version of Record online: 20 FEB 2017 | DOI: 10.1002/dac.3292
In this paper, we investigate the resource allocation and interference mitigation problem in cluster based OFDMA two-tier HetNets. To compensate hybrid access small cells for their resources loss, we impose hierarchical user throughput constraints on the optimization problem, which guarantee these small cells more resources than closed access ones. Based on the subgradient iteration, a joint subchannel and power allocation algorithm is proposed.
