Erasure Correction for Noisy Radio Networks [article]

Keren Censor-Hillel and Bernhard Haeupler and D Ellis Hershkowitz and Goran Zuzic
2019 arXiv   pre-print
In this work we quantify the relative computational power of noisy radio networks and classic radio networks.  ...  The recently introduced noisy radio network model relaxes this assumption by dropping messages independently at random.  ...  [33] consider radio networks with possibly correlated faults at nodes.  ...

Evaluation of Channel Assignment Performance Prediction Techniques in Random Wireless Mesh Networks [article]

M Pavan Kumar Reddy, Srikant Manas Kala, Bheemarjuna Reddy Tamma
2015 arXiv   pre-print
We obtain conclusive results to demonstrate the efficacy of proposed schemes in random WMNs as well.  ...  Thus, interference alleviation is a fundamental design concern in multi-radio multi-channel (MRMC) WMNs, and is achieved through a judicious channel assignment (CA) to the radios in a WMN.  ...  We illustrate the expected correlation in Figure 1 . With rise in interference the performance of a wireless network deteriorates.  ...

A Review Study on Analytical Estimation of Optimal Number of Clusters in Wireless Sensor Networks

Vinay Kumar, Sanjay B Dhok, Rajeev Tripathi, Sudarshan Tiwari
2014 Transactions on Networks and Communications  
WSNs are large-scale networks of small embedded devices, each with sensing, computation and communication capabilities and have been widely discussed in [1, 2, 8, 20] .  ...  Selection of optimal number of clusters in WSNs is affected by level at which WSNs is modeled viz. Radio Energy Model Level, Network Model Level and Clustering Level.  ...  It is found that with non-uniform clustering in heterogeneous WSNs, clusters are more energy-efficient in WSNs with spatial data correlation.  ...
