With the development of wireless networks, the scale of network optimization problems is growing correspondingly. While algorithms have been designed to reduce complexity in solving these problems under given size, the approach of directly reducing the size of problem has not received much attention. This motivates us to investigate an innovative approach to reduce problem scale while maintaining...
Periodically research focusing on the level of security in home wireless networks, would reveal a considerable percentage of insecure networks. Labeling them as such, could come from either failing to utilise appropriate security standards or by using the obsolete ones. Relevant data specifying the security standards used was collected by performing an act of wardriving. The essential part of it would...
Given the emergence of the wireless technologies in the recent past, their utilities in both home and industrial applications have taken new shapes in various dimensions. Along with this progressive growth is the substantial emergence of the network attackers as they are finding new bases and platforms for launching network attacks. Existing wireless security standards are not persistent enough under...
Multi-radio multi-channel (MR-MC) networks as a promising technique to enhance the capacity of wireless networks have received a lot of attentions recently. While most of the existing studies focus on capacity optimization, energy-efficient resource allocation for MR-MC networks is an emerging area yet to be exploited. In this paper, we develop an optimization framework for energy-aware optimal resource...
In this paper, we analyze and evaluate the cost-delay trade off of opportunistic network coding in a two-way relay network with asymmetric arrival rates. We first formulate the variance of the queue into a Markov chain and derive the transition probability and the stationary distribution. Then we analyze the average power cost and delay, formulate the optimal power-delay trade off, and propose a heuristic...
